Abstract: Compressor unit (12) of a compressor (10) for compressing refrigerant, comprising a drive device, particularly a drive shaft (24), for driving one or more pistons (14) that are arranged in a radial direction and that can be moved back and forth in extension and retraction movements in corresponding cylinder bores (16), wherein the drive device is in operative engagement with an eccentric (28) that controls the extension movement of the pistons (14), said eccentric (28) also controlling the retraction movement of the piston (14), the invention further relating to a corresponding compressor (10).
Abstract: A compressor (10, 100), comprising a compressor housing (15), a drive mechanism (12), and a compressing unit (14) having one or several compression levels (14-1, 14-2) for compressing a cooling agent, wherein the compressor (10, 110) is further provided with one or several cooling agent feeder units (20, 36) for feeding cooling agents to the compressing unit (14) and with one or several cooling agent discharge units (24, 38) for discharging cooling agents from the compressing unit (14). At least one segment of the one cooling agent feeder unit or at least one segment of at least one, in particular each one of the several cooling agent feeder units (20, 36), is arranged thermally separated from the one cooling agent discharge unit or at least one, in particular each one of the several cooling agent discharge units (24, 38).
Abstract: A compressor (10, 200) for compressing refrigerant, having a power unit arranged in a power unit space (14) which is delimited at least partially by a power unit housing (12), having a suction gas volume (46) and having a high-pressure volume (48) is in fluid communication with the power unit space (14) via a second fluid connection (74), wherein the compressor furthermore has a first fluid connection (54, 254) which can be placed in or is in fluid communication with an oil-conducting volume (205) of a refrigeration plant or of the compressor (10, 200), wherein an oil separator (56) is arranged in the first fluid connection (54, 254).
Abstract: A compressor, in particular a radial piston compressor, further in particular a compressor for CO2 as a refrigerant, including a compressor unit for compressing refrigerant and a drive shaft for driving the compressor unit and a motor chamber bounded substantially by a motor housing, wherein the motor chamber has a fluid connection to a suction gas side, in particular a suction gas chamber, of the compressor by means of a fluid connection formed at least partially in the drive shaft, wherein at least one device for accumulating oil is arranged in the fluid connection.
