A swash plate type compressor is provided with a plurality of cylinders and a front and rear cylinder blocks having a crank case connected to a suction port. The cylinder blocks are connected to a front and rear housing sections in order to cover the cylinders. Each housing section contains a discharge chamber. A drive shaft is rotatable supported by the cylinder blocks. One end of the drive shaft is sealed within the front housing. A swash plate is mounted on the drive shaft and is rotatably disposed within the crank case. A plurality of two-head pistons engage the swash plate via a pair of shoes. The pistons move within their respective cylinders in cooperation with the swash plate. The refrigerant is sucked into each cylinder via a suction passage, and is then compressed therein. The refrigerant is discharged into the external refrigerating circuit through the front and rear discharge chambers, .and the front and rear discharge ports. A discharge passage is provided within the drive shaft, and interconnects the front and rear discharge chambers. A valve is provided at one end of the discharge passage to control the opening of the discharge port in relation to the pressure difference between the front and rear discharge chambers.
In a swash plate type compressor of the type having a drive shaft, a plurality of discharge chambers which form a part of a discharge passage, the improvement comprising:
A compressor comprising:
A compressor including a pair of cylinder blocks having a plurality of cylinder and a crank case leading to a suction port, a pair of housing sections having at least two discharge chambers, and covering both ends of the pair of cylinder blocks, a drive shaft being rotatably supported by the pair of cylinder blocks, a swash plate being mounted on the drive shaft and rotatably housed within the crank case, a plurality of pistons engaging the swash plate and moving within the cylinders in cooperation with the swash plate, wherein the refrigerant flows from the suction port into the cylinders via a suction passage, is compressed within each cylinder, and is discharged into the discharge chambers via discharge ports which communicate with the discharge chambers, the compressor comprising:
