Figure 1 shows a cross-section shown also air compressor, Figure 2 shows a cross-section of the present invention disk brake for car according to major part for the enlargement also are disclosed. Hereinafter with reference to the drawing, according to one embodiment of the present invention detailed to explain a hole of for example for vehicle air compressor. Figure 1 shows a cross-section shown also air compressor are disclosed. As shown in fig. 1, generally air compressor (10) is formed between housing (100) and, housing (100) is coupled to the front of the blowing air impeller (400) receiving the impeller receiving portion (200) and an impeller (300) and, housing (100) coupled to the back of the rear cover (500) on, housing (100) is installed in the up (400) to be rotationally driven a blower motor (600) consists of including. An impeller (300) is provided at the center wrap front of the air inlet (310) is formed, on the front is provided with an air discharge port (330) is formed. Impeller (400) includes an impeller (300) is installed in the of, impeller (400) the hollow the after alcoholic beverage it will do through blower motor (600) the axis of rotation (650) is coupled. I.e., impeller (400) includes a shaft (650) supported by the substrate. Impeller (400) by an air inlet (310) air is drawn through the impeller (400) to compression by type a air conditioner (330) discharged into the other. Rear cover (500) includes a housing (100) of a rear shaft (650) so as to prevent cutting, shaft (650) are retained with the right end of. Blower motor (600) includes a housing (100) inserted inside the motor housing (600a) are associated with them. Blower motor (600) includes a motor housing (600a) is rotatably mounted adjacent the inner peripheral surface of hollow (number american marking) having a stator (630) on, stator (630) provided through the hollow shaft (650) and, rotation (650) an outer peripheral surface of rotor (610) to consists of. Stator (630) to plate (630a) and coil (630b) is disposed at the composed, rotor (610) is an axis of rotation (650) outer circumferential surface of the integrally formed. Rotation (650) comprise longitudinally formed therethrough along hollow hollow shaft among others. Rotation (650) has one end impeller (400) hollow engagement running wheel (400) of a vehicle and which is supported by the thrust bearing (thrust bearing, 700). Thrust bearing (700) axis (650) moving in a direction perpendicular axis (650) support the foot panel 50. Thrust bearing (700) adjacent to the rotating shaft (650) an outer peripheral surface of a front journal bearing (730), rotation (650) rotatably supporting one end of a rear journal bearing (730) and rear bearing (800) is combined with each other (hereinafter the for the sake of convenience motor shaft toward the impeller end forwardly, an opposed rearward as the user-definable). Blower motor receives power from the outside (600) operated, shaft (650) while rotating the impeller (400) and rotationally driving the, air is an air inlet (310) to enter through impeller (400) passing following compression type a air conditioner (330) discharged into the other. Blower motor (600) to cool heat generated during operation of the housing (100) with an coolant jacket (110) is combined with each other. Cooling water jacket (110) comprises a housing (100) within the housing (100) has a form which surrounds, cooling water is supplied therein overnight. Cooling water jacket (110) is blower motor (600) with a cooling water through heat exchange with adjacent to the blower motor (600) for cooling could be bonded each other. Blower motor (600) of cooling water cooling jacket (110) in addition to cooling using air blower motor (600) for cooling air-cooled cooling method is blended with each other. Blower motor (600) (P1) is a cooling passage for cooling air inlet (310) and an impeller (400), type a air conditioner (330) communicating with the air compression passage communicates with a. Cooling passage (P1) the impeller (400) impeller receiving portion (200) from between the front journal bearing (730) and the rotation (650) to the rear journal bearing between (730) and the rotation (650) past between rear cover (500) communicates with a up. Rear cover (500) moves toward the air rear cover (500) and a rotating shaft (650) of between an (650) through a central axis of the hollow along an air inlet (310) communicates with a up. The aforementioned path (P1) and the cooling passage in such, impeller (400) along a portion of the air is compressed by means of the cooling passage in such (P1) thrust bearing rotationally (700) and front journal bearing (730) and cooling blower motor (600) thereafter the rear bearing (800) to a hollow cooling air through the inlet (310) towards the exhaust therefrom. Placed between the impeller (400) exit temperature of the air if 110 Celsius e.g. also as a, front journal bearing (700) after cooling temperature of the air is about 130 also about Celsius. Blower motor (600) past the rear journal bearing (730) inlet inlet temperature Celsius degree and also about 140, rear bearing (800) also decreased the temperature of the air is under or over 190 degree Celsius. The impeller (400) advance order receipt number from air hole axis (650) one or rear thrust bearing (800) outputs sufficiently cool, additional cooling flow path the spirit. Figure 2 shows a cross-section of the present invention disk brake for car according to major part for the enlargement also are disclosed. As shown in fig. 2, according to one embodiment of the present invention example additional cooling passage for vehicle air compressor housing (100) on the circulation passage for circulating air outside (P2), circulation passage (P2) communicates with cooling water jacket (110) including a bypass passage (P3) which circumvent around consists of. Circulation passage (P2) the impeller housing (100) of type a air conditioner (330) operating on a side of the sheet (rotating together in the activatable 160 static recovery to enhance, the publicly known techniques described as the V-shaped) (P3) compressed air that is discharged from the bypass flow path enters the reaction chamber. The circulation passage (P2) end type a air conditioner (330) and joined to the operating, bypass passage (P3) while the other end is connected thereto. Circulation passage (P2) includes a housing (100) with considering the pinion is in engagement with the periphery outside of the housing (100) preferably is integrally formed with an external force acts. To this end, housing circulation passage (P2) (100) may be detachably coupling outside, with separate attachment can be. Bypass passage (P3) (P2) circulation passage is connected with one end, the other end housing (100) connected to the inside of the impeller (400) on bearing casing (750) communicates with a between. In addition, bypass passage (P3) is a coolant jacket (110) adjacent to the housing (100) through to the inside of the formed along the longitudinal direction. Bypass passage (P3) is compressed air and cooling water jacket (110) while cooling with a cooling water temperature exchange moves along and n is an integer. (P2) (P3) compressed air temperature entering the circulation passage or bypass passage are cooled cold through the vehicle from the outside. As it passes through a bypass passage (P3) cooled air is a housing (100) flowing in with each other. On the other hand, bearing casing (750) is a communication hole (752) is formed through an ornamental portion, a communication hole (752) is thrust bearing (700) with motor housing (600a) into the interior of the communicates with a. Housing (100) of cooling air into a rotation (650) on bearing casing (750) enters between the thrust bearing (700) and the bearing casing (750) move along between, journal bearing (730) and the rotation (650) of from between other. Some of the cooling air communication hole (752) through thrust bearing (700) supplied directly towards a wiring cool, journal bearing (730) and the rotation (650) moves to between. Thrust bearing (700) and journal bearing (730) cooling air cooled shaft (650) moving along the outer circumference of the rotary (650) and rotor (610) is a method for, rear journal bearing (730) and rear bearing (800) sequentially after cooling shaft (650) along cavity formed in the upper air inlet (310) towards the discharge therefrom. The circulation passage (P2) and (P3) bypass passage and the coolant is fed with cooling air using the, rear bearing (800) thereafter degrees or greater can be produced from the house to drop. The circulation passage (P2) and (P3) before bypass flow with increases cooling efficiency than can be. The bearing and rotor of efficient cooling effects with the first air compressor, air compressor into communication with separate cooling passage of air leakage to the outside and is bent by the pin is.
