In order to improve a reciprocating piston compressor for a refrigerant circuit, comprising a crankcase, in which a collecting chamber for lubricant is arranged, a cylinder housing, in which at least one reciprocating piston is movable in an oscillating manner, a valve plate which closes the cylinder housing and in which at least one inlet valve and one outlet valve are arranged, and a cylinder head, in which a suction gas duct which runs to the inlet valve and a compressed gas duct which leads away from the outlet valve are provided, in such a manner that excessive accumulations of lubricant can be avoided, it is suggested that a lubricant suction conduit be provided which has an inlet opening associated with the collecting chamber and an outlet opening associated with the suction gas duct and that the outlet opening be located in an area of the suction gas duct, in which a static pressure, which is lower than a static pressure in the collecting chamber for lubricant, prevails at least temporarily.
