Abstract
A swash plate type compressor for use in air conditioning systems operating with a refrigerant gas in which lubricating oil is previously mixed, comprises a plurality of cylinder bores and pistons, a swash plate chamber wherein a swash plate for reciprocating the pistons within the cylinder bores, is accomodated, a plurality of suction passages communicated with the swash plate chamber, suction chambers and exhaust chambers communicated with the cylinder bores, respectively and at least one sub-suction chamber communicated with the suction chambers through a shaft seal chamber wherein a shaft seal member is accomodated. At least one suction passage which is communicated with the swash plate chamber in the bottom portion thereof is communicated with the sub-suction chamber and the other suction passages are communicated with the suction chambers. The refrigerant gas and liquid oil stayed in the bottom portion of the swash plate chamber is flowed into the shaft seal chamber through the suction passage which is communicated with the bottom portion of the swash plate chamber, and subsuction chamber. The refrigerant gas and liquid oil lubricates and cools the shaft seal member accomodated within the shaft seal chamber and is atomized due to the operation of the shaft seal member. Then, the atomized refrigerant gas is flowed into each of the cylinder bores through the suction chambers. Therefore, the refrigerant gas is uniformly compressed within each of the cylinder bores without generating liquid compression.
