Abstract
A wobble plate compressor which is adapted to vary the angularity of the wobble plate during rotation in response to the difference between the resultant reaction force exerted by the pistons on their compression and suction strokes and the pressure in the crankcase. The compressor has a passage with an orifice communicating a lower pressure space therein with the interior of the crankcase, a communication passage communicating a higher pressure space therein with the interior of the crankcase, and a control valve means for controlling the opening of the communication passage. Preferably, the cross-sectional area of the above orifice passage is set at such a value as to permit blow-by gas leaking from the cylinders into the crankcase to escape from the crankcase into the lower pressure space at a flow rate at least equal to the maximum possible flow rate at which the blow-by gas leaks from the cylinders into the crankcase.
