Valve

The invention relates to a valve (10) which is essentially composed of a flap (13), a flap frame (12) and a unitary housing (11). Said flap (13) is rotatably received in the flap frame (12) and it is arranged in said flap frame (12) so that, in a closed position, it allows only minimal leakage which is of no significance to the operation thereof. The flap frame (12) has a precision region (21) for preventing an abrupt flow change. The unitary housing (11) is cast in a tool wherein the pre-mounted valve parts (12, 13) are arranged. Direct casting of the housing (11) around the valve parts (12, 13), enables the production of several housing parts, mounting and sealing to be dispensed with. Said housing (11) can be connected to adjacent components in a leakproof manner and in addition, connecting sleeves for crankcase ventilation or tank ventilation etc.can be integrated to said housing (11). Said valve (10) can be used as a butterfly valve for a combustion engine.
