<p>Compressor (1) having a region of pressure intermediate between discharge pressure and suction pressure (especially crank compartment (10)), characterized by being equipped with valve means (21) for introducing any discharge gas in the region of intermediate pressure so as to render constant the difference between intermediate pressure and suction pressure. Accordingly, there can be provided a compressor structure that without the use of depressurization means, such as aperture, stably introduces a mixture of discharge gas and refrigerant oil in the crank compartment in a method ensuring easy formation of pathway to thereby enhance the lubrication of rolling part and slide part within the crank compartment.</p> |
