Abstract: A crankshaft (1) for a refrigerant compressor, the crankshaft (1) at least comprising a cylindrical shaft element (2), a crankpin (3) for driving a compressor piston of the refrigerant compressor, and means for conveying lubricant from a lower end region (4), facing away from the crankpin (3), of the shaft element (2) in the direction of the crankpin (3), in order to supply lubricant to movable parts of the refrigerant compressor, wherein at least one surface section of a surface of the crankshaft (1) comprises at least one flow disruptor, which flow disruptor is, based on the geometry and/or characteristics thereof, configured to break up vapor bubbles and/or gas bubbles in the lubricant flowing around the crankshaft (1) in an operating state of the refrigerant compressor.

Abstract: The invention relates to a lubricant receptacle (1) for vertically conveying lubricant by means of a crankshaft (2) of a coolant compressor (3), said lubricant receptacle (1) comprising at least one rotationally symmetrical, sleeve-type receiving section (4) for receiving lubricant, wherein the longitudinal axis (8) of the receiving section (4) can be arranged coaxially with a longitudinal axis of the crankshaft (2) of the coolant compressor (3), and comprising a securing section (16) connected to the receiving section (4) in order to secure the lubricant receptacle (1) on the crankshaft (2), as well as comprising at least one end region (5) connected to the receiving section (4) which closes the the receiving section (4) apart from an inlet opening (6), wherein the inlet opening (6) permits the entry of lubricant from a lubricant sump (7) of the coolant compressor (3) into the receiving section (4) of the lubricant receptacle (1) protruding at least partially into the lubricant sump (7), wherein the inlet op

Abstract: A device for fastening the housing (2) of a refrigerant compressor at a container enclosing a cooling volume, wherein the housing (2) can be fastened to a support element (1) located at the container by way of an arbitrary number of connecting elements (3), wherein at least one connecting element (3) is provided that can be fixed in clamped or latched fashion in at least one corresponding receptacle (4), wherein the at least one connection element (3) and the at least one receptacle (4) can be located either at the housing (2) or at the support element (1). In order to facilitate a simple, fast and nevertheless reliable fastening of the refrigerant compressor at the support element (1), it is provided according to the invention that the housing (2) can be moved from a first mounting position in which the at least one connection element (3) is laid into the at least one receptacle (4) to an operating position in which the connection element (3) is fixed in the receptacle (4) in clamped or latched fashion.

Abstract: Device for fastening the housing (2) of a refrigerant compressor on a container enclosing a cooling volume, wherein the housing (2) can be fastened by means of an arbitrary number of connection elements (3) on a carrier element (1) arranged on the container, wherein at least one connection element (3) is provided that can be fastened in a clamped or latched manner in at least one corresponding receptacle (4), wherein the at least one connection element (3) or the at least one receptacle (4) can be arranged selectively on the housing (2) or on the carrier element (1).
