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: The invention relates to a hermetically encapsulated refrigeration compressor comprising a hermetically sealed compressor housing containing a piston-cylinder unit compressing a refrigerating agent. The cylinder is closed by means of a valve plate comprising a pressure borehole and a suction borehole, and a suction channel and a pressure channel are used to suck the refrigerating agent into the suction borehole by means of a suction valve, and to compress the refrigerating agent passing from the pressure borehole into the pressure channel by means of a pressure valve. Preferably, a suction sound absorber is arranged in the suction channel. The aim of the invention is to create one such refrigeration compressor that enables a significant decrease in the suction temperature and the exhaust temperature.

Abstract: A hermetically encapsulated refrigerant compressor, comprising a hermetically sealed compressor housing, in the interior of which a piston-cylinder unit works which compresses a refrigerant, whose cylinder housing (3) is sealed by means of a valve plate (16) comprising a pressure bore (25) and an intake bore (15), and an intake duct and a pressure duct are provided through which refrigerant is drawn into the intake bore (15) via a suction valve and is compressed via a pressure valve from the pressure bore (25) into the pressure duct, with a muffler (11) preferably being arranged in the intake duct. A clamping element (18) is provided which clamps the valve plate (16) at least along a section of its circumference, preferably along the entire circumference, against the cylinder housing (3).

Abstract: Disclosed is a compressor for hermetically sealed small refrigeration machines. Said compressor comprises a cylinder with a cylinder housing (4) and a piston that is guided in the piston bore of the cylinder and is used for compressing a working medium, the cylinder being closed in an axial direction by means of a cylinder head (1). According to the invention, a fastening element (2, 24, 25) is provided which fixes the cylinder head (1) to the cylinder housing (4) using contact pressure that is applied in the area of the axis of the piston bore. Said fastening element can be embodied as a clamp (2), a locking clip (24), or an elastically bendable fastening means (25) such as a rope (25). The clamp (2) can be provided with a base part (5) and lateral parts (6), for example, the base part (5) being disposed in front of the cylinder head (1) in an axial direction.
