joining a housing of the refrigerant compressor to a device that is in operative connection with the refrigerant compressor, the connection component comprising an inner element and an outer element surrounding the inner element, where the inner element has a higher stiffness than the outer element and the outer element has a functional segment that is designed so that in a loaded state of the connection component it is supported both at the housing and also at the device. ## Claims ### Claim 1 A connection component of a refrigerant compressor for joining a housing of the refrigerant compressor to a device that is in operative connection with the refrigerant compressor, the connection component comprising an inner element and an outer element surrounding the inner element, where the inner element has a higher stiffness than the outer element and where the outer element has a functional segment, which is designed so that in a loaded state of the connection component it is supported both at the housing and at the device, where in the loaded state a relative movement between the housing and the device and parallel to an axial direction exits and compressive load parallel to the axial direction prevails, where a free space is provided, which, looking in a transverse direction joins the functional segment of the outer element, where the inner element and the outer element, looking parallel to the transverse direction, are disposed one behind the other and where in the loaded state of the connection component the functional segment is deformed so that it at least in part protrudes into the free space, characterized in that the outer element has an inner segment disposed closer to the inner element and an outer segment, where the functional segment is formed by one of the two segments and of the two segments only the functional segment is supported both at the housing and at the device in the loaded state, and in that in the loaded state of the connection component, the deformed functional segment abuts at least in part an abutment member of the connection component which abutment member, looking in the transverse direction, abuts the free space. ### Claim 2 (depends on 1) The connection component as in claim 1, characterized in that the deformed functional segment comprises a segment with a bend, where the segment of the functional segment having the bend at least partially protrudes into the free space. ### Claim 3 (depends on 1) The connection component as in claim 1, characterized in that the abutment member of the connection component is formed by the inner element. ### Claim 4 (depends on 1) The connection component as in claim 1, characterized in that the free space is formed at least in part between the inner segment

element is made of rubber or an elastomer. ### Claim 13 (depends on 1) A refrigerant compressor, comprising a hermetically sealed housing and a drive unit having a piston-cylinder unit for cyclic compression of a refrigerant and an electric motor to drive the piston-cylinder unit, which are disposed within the housing, where the refrigerant compressor further comprises at least one connection component as in claim 1 to join the housing to a device that is in operative connection with the refrigerant compressor. ### Claim 14 (depends on 13) A system comprising a refrigerant compressor as in claim 13 and a device that is in operative connection with the refrigerant compressor, where the device comprises a mounting panel, to which the housing of the refrigerant compressor is joined with

connection component. ### Claim 16 (depends on 1) The connection component as in claim 1, wherein the device comprises a mounting panel of a refrigerator. ### Claim 17 (depends on 10) The connection component as in claim 10, characterized in that the two segments are joined to each other in the region of an end region of the relevant segment. ### Claim 18 (depends on 13) The refrigerant compressor as in claim 13, wherein the device comprises a mounting panel of a refrigerator. ### Claim 19 (depends on 14) The system as in claim 14, wherein the refrigerant compressor comprises a refrigerator.
