A device for compressing a gaseous fluid, in particular a refrigerant in a refrigerant circuit, specifically of an air-conditioning system of a motor vehicle. The device has a housing, a compression mechanism for compressing the gaseous fluid, and an electric motor for driving the compression mechanism. The housing is formed with a suction-pressure chamber and a high-pressure chamber.

Device for compressing a gaseous fluid and method for operating the device

Devices for compressing a gaseous fluid each have a housing with a cylindrical cavity configured in the housing, in which a spiral nozzle assembly is arranged. As such, the spiral nozzle assembly is configured with a spirally revolving winding with a winding surface, which at least partially sealingly abuts an inner wall of the cylindrical cavity. Recesses configuring a filter function and a bypass function are arranged on the winding surface of the spirally revolving winding, or the winding surface of the spirally revolving winding is arranged to be spaced apart from the inner wall of the cylindrical cavity with a distance configuring a gap for a filter function and a bypass function in at least one partial area. Additionally thereto, or instead thereof, recesses configuring a filter function are each arranged on a collar surface of a collar connected to the spiral nozzle assembly.

Devices for compressing a gaseous fluid and method of operating a device for compressing a gaseous fluid

An apparatus for damping pressure pulsation for a compressor of a gaseous fluid in a refrigerant circuit including a housing with an inlet opening and at least one first outlet opening and a piston element movable in an axial direction within a volume enclosed by the housing and supported on the housing in a beared manner via a spring element, wherein the piston element respectively controls a flow cross section of the inlet opening and the first outlet opening, wherein the piston element and the housing have at least one first sealing surface and a second sealing surface. The first sealing surfaces form a first seat and the second sealing surfaces form a second seat, wherein between the seats, one chamber enclosed by the housing and the piston element for expanding the fluid when flowing into the chamber and/or at least one second outlet opening in the housing is formed.

Apparatus for damping pressure pulsation for a compressor of a gaseous fluid

A device for controlling a fluid mass flow for a device for compressing a gaseous fluid from a low to a high pressure level. The device has a housing with fluid connections at different pressure levels, and a closure element arranged to move in a translatory manner within the housing along a longitudinal axis, with effective surfaces assigned to the fluid connections. The closure element regulates a flow cross-section of a flow path extending between a first and a second fluid connection. The device has a receiving element for receiving the closure element. A primary segment is arranged to be completely surrounded by the receiving element as a first section of the closure element and a secondary segment is arranged to be completely surrounded by the housing as a second section of the closure element and the receiving element is arranged to be completely surrounded by the housing.
