摘要： The invention relates to a semi-hermetic coolant compressor, comprising a reciprocating compressor, an electric motor, a complete housing which has a motor housing section for the electric motor and a compressor housing section for the reciprocating compressor, a suction-side coolant path which leads from a suction connection on the complete housing to an inlet chamber of the reciprocating compressor, and a pressure-side coolant path which leads from an outlet chamber of the reciprocating compressor to a pressure connection on the complete housing. The aim of the invention is to improve such a coolant compressor such that the coolant compressor functions more efficiently. This is achieved in that the electric motor is designed as a synchronous motor, the rotor of which is equipped with permanent magnets for the synchronous operation of the electric motor and a squirrel cage for starting up the electric motor in the asynchronous operation.

摘要： 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.
