ABSTRACT:
A swash-plate type compressor comprising a cylinder block, front and rear valve plates, and front and rear housings attached to either end of the cylinder block over the valve plates. A swash-plate is accommodated in the cylinder block to reciprocally move a plurality of double headed pistons which form compression chambers on either side thereof. A drive shaft carries the swash-plate and is supported by a pair of tapered roller bearings. Each of the tapered roller bearings is secured in the central hole of each valve plate. Also, each valve plate is coupled to the cylinder block in a locating projection-locating hole fitting relationship to effect centering the drive shaft relative to the cylinder block. In addition, a suction passage is arranged to introduce the refrigerating gas from the swash-plate chamber to each of the compression chambers in such a manner as to reduce the radius of the cylinder block.
