ABSTRACT:
A reciprocatory piston type compressor having a cylinder block provided with a plurality of cylinder bores in which a refrigerant gas drawn from a suction chamber is compressed and discharged toward a discharge chamber from which the compressed refrigerant gas is delivered to a refrigeration system. The compressor further having an injection gas passageway for introducing a refrigerant gas at a relatively high pressure therein from a liquid-gas divider of the refrigeration system, and a rotary valve element rotated with a drive shaft of the compressor for equivalently injecting the high pressure refrigerant gas into every cylinder bore at a selected time and the compression of the refrigerant occurs in each cylinder bore.
