Abstract

A variable capacity single-headed piston type compressor having a cylinder block defining therein a plurality of cylinder bores in which single-headed pistons are reciprocated so as to compress refrigerant gas in response to a rotation of rotation-to-reciprocation converting unit arranged in a crank shaft defined by the cylinder block and a front housing hermetically attached to a front end of the cylinder block, the crank chamber being provided with a suction gas inlet port formed so as to open into the crank chamber, a rear housing hermetically attached to a rear end of the cylinder block and defining a suction chamber for the refrigerant gas before compression and a discharge chamber for the refrigerant gas after compression, the suction chamber being in fluid communication with the crank chamber so as to receive the refrigerant gas from the crank chamber via a fluid passageway for the suction of the refrigerant gas, and a flow regulating valve arranged in the fluid passageway to adjustably change the cross-sectional area of the fluid passageway to thereby control the pressure in the suction chamber.
