Blow-by gases from the opposite side of the rotor pass through passages 78, 76 in the eccentric 34 and plate 60 to space 70 to assist the pressurized gas in its sealing function. However, upon braking of the engine, the blow-by gas pressure would not be sufficient, and the pressurized gas source 80 is particularly needed in this situation.

Internal combustion engine with rotary piston

Oil seal for piston of rotary engine - uses oil press. to keep scraper rings on inner ring pressed against rotor

The scraper rings (16) are located in grooves in a ring (14) containing grooves for 0-rings (20) and (24). The annular space (22) communicates with a hole (26) to which high pressure oil is supplied. The oil pressure forces the ring (14) against the scraper rings (16) which prevent oil leaking into the compression chamber. To remove oil which seeps past the 0-rings a hole is bored through the ring (14) and a pipe fitted to lead the oil away through a hole similar to the hole (26) but in a different part of the ring. Sealing load can be increased by compression springs which maintain the load in the event of oil pressure failure.

A rubber ring 17<SP>1</SP> is provided in each sealing ring to effect sealing between the ring and an adjacent flange 19 on the periphery of the associated annular member, the ring being biased in the direction of the piston by a leafspring 17. Each of the annular members has a central tubular hub 22, or 23, in engagement with an aperture in the adjacent side wall 3, or 4, of the engine housing, spiral grooves 23 being formed in said hubs to seal a clearance gap 24. Cooling of the piston is accomplished by circulation of lubricant through passages 30, 31 in the annular members and a cavity 13 in the piston, the lubricant also serving to lubricate gearing 10, 11 for controlling the planetary motion of the pistons, a bearing 9 supporting the piston on the eccentric, and bearings for a power-output shaft 6. Each of the rings 16 may be replaced by a ring 16<SP>1</SP> (Fig. 3, not shown) which is pressed by springs against a ring 25 attached to the piston and having a flange 25 mating with a groove in the associated annular member. An outwardly-inclined gap 27 between each annular member and the corresponding ring 25 serves to return lubricant by centrifugal action to cavity 13. Alternatively, sealing between the annular members and the piston is effected by the provision of a narrow gap between each ring 25 and the associated annular member (Fig. 4, not shown), or each ring 25 has axially-extending flanges mating with grooves in the adjacent annular member to form a labyrinth seal (Fig. 5, not ...

Rotary piston internal combustion engine

A rotary piston internal combustion engine of trochoidal-type of construction with a slidably journalled piston controlled by a synchronous transmission gear drive unit, with which the synchronous transmission gear drive unit is covered coinciding with an insert part threaded with respect to the remaining machine parts adjacent to the eccentric. The insert part has a hollow cylinder covering the hollow gear of the synchronous transmission gear drive unit eccentric to the eccentric shaft, which hollow cylinder is sealed-off with a sealing ring relative to one shoulder of the piston, as well as a further hollow cylinder coaxial to the eccentric shaft surrounding the holding part for the pinion with a gap or space therebetween, which further hollow cylinder projects into a shaft bore in the side part and is sealed-off relative thereto by a sealing ring. Upon another bearing side there is provided an annular chamber sealed-off relative to the remaining machining spaces or chambers and from which annular chamber the oil discharging from the bearing is conveyed through the cooling chambers of the piston to the synchronous transmission gear drive unit. The oil is discharged through a gap space in a discharge passage or channel in the sidewall formed by the coaxial hollow cylinder.
