Variable delivery compressor with eccentrically mounted rotor - has by=pass channel between chambers which is opened and closed by folding bellows.

摘要

Compressor with variable delivery output having a housing (11) with a cavity (12a) containing an eccentrically mounted rotor (16) which determines a compression chamber (22) and a suction chamber (21). A bypass channel (26a) with the shape of a slotted hole produces a fluid connection between the compression chamber and the suction chamber, and a folding bellows opens and closes the bypass in relation to pressure in the suction chamber. USE/ADVANTAGE - Compressor for a vehicle air conditioning system capable of operating at high speed and responsive to demand loads.
