Abstract (en)

A reciprocatory piston type compressor having an axial cylinder block (1) in which a plurality of axial cylinder bores (1b) are formed for receiving pistons (15) therein to compress a refrigerant and to discharge the compressed refrigerant, housings (2,4) air-tightly connected to the opposite ends of the axial cylinder block to define a suction chamber (17) for the refrigerant before compression, a discharge chamber (18) for the refrigerant after compression, and a chamber (5) for receiving a swash plate accommodated piston reciprocating mechanism operated by a rotatable drive shaft (6) axially extended through the chamber (5), and a rotary valve element (22) arranged so as to be rotated together with the drive shaft (6) and having a fluid passageway (25) for controlling the supply of the refrigerant from the suction chamber (17) to the respective cylinder bores (1b) in response to rotation thereof. The rotary valve element (22) may also have another fluid passageway for controlling the discharge of the compressed refrigerant from the cylinder bores to the discharge chamber (18) in response to rotation thereof. <IMAGE>
