Abstract

A swash plate type compressor for use in an air-conditioning system for vehicles. The compressor has a pair of cylindrical cylinder blocks which are disposed in axial alignment and contact with each other, cylinder bores formed in the cylinder blocks and pistons reciprocatably received by respective cylinder bores. A rotary shaft extends through the cylinder blocks coaxially with the latter, and carries a swash plate fixed thereto. The pistons are slidingly engageable with the swash plate such that they make reciprocating movement in respective cylinder bores as the swash plate is rotated. The swash plate is accommodated by a crank chamber defined in the pair of cylinder blocks. A lubrication oil is supplied to the sliding parts in the crank chamber. A pair of side plates are attached to respective ends of the cylinder blocks which are axially disposed and contacted by each other, through medium of valve plates. The side plates cooperate with corresponding valve plates in defining therebetween suction chambers. The suction chambers are in direct communication with the crank chamber so that the blow-by gas within the crank chamber is sucked into the suction chambers. An oil chamber …
