ABSTRACT:
A piston-type compressor includes a cylinder having a liner sleeve in which is mounted a reciprocating piston driven by a crankshaft through a connecting rod. The piston forms a dynamic seal with the sleeve with the volume above the piston head defining a first, or compression chamber. Connected between the piston and the compressor cylinder is a flexible sealing element such as a bellows which defines a second, isolating chamber between the bellows and the dynamic seal and which further defines a third, or crankcase chamber between the bellows and the region of the compressor which includes the crankcase. The volumes in the second and third chambers are chosen so that the pressures therein are generally equal. A bypass filter assists in eliminating the pressure differential across the bellows during startup by maintaining the pressure within the intermediate and crankcase chambers substantially equal. The bellows and bypass filter cooperate to prevent contamination from the crankcase from reaching the isolating chamber or the compression chamber.
