摘要： A process for manufacturing a device and the device for damping pressure pulsations for a compressor of a gaseous fluid, in particular a refrigerant, in a refrigerant circuit of a motor vehicle air-conditioning system. The device exhibits a housing that encompasses a chamber and features at least two outlet openings. Here, the housing is constructed between tubular connecting lines, whose ends are aligned with one another. An insert element for reducing the cross-sectional area of the pass-through opening is arranged inside at least one of the pass-through openings.

摘要： The invention relates to a device (1) for damping pressure pulsations for a compressor of a gaseous fluid, in particular of a refrigerant. The device comprises a housing (2), a piston element (6) as well as a spring element (8). The housing (2) is developed encompassing a chamber (3), with an inlet opening (4) and an outlet opening (5). The piston element (6), supported such that it is stayed across the spring element (8) on the housing (2), is disposed within the chamber (3) dividing the chamber (3) into a first chamber volume (3a) and a second chamber volume (3b), as well as being disposed movably in a direction of motion (11) between a first end position and a second end position. The motion of the piston element (6) effects a change of the chamber volumes (3a, 3b) and of a flow cross section of the outlet opening (5). The piston element (6) is developed as a hollow cylinder with two, at least partially closed, end faces (7, 13). The piston element (6) herein comprises at least one through-opening (14, 15) developed as a fluidic connection between a chamber volume (3a, 3b) and a volume encompassed by a wall of the piston element (6).

摘要： A device for compressing a gaseous fluid from a low-pressure section into a high-pressure section. The device has a housing with a housing member, a compression mechanism arranged between the low-pressure section and the high-pressure section as well as a flow duct connecting the high-pressure section to the low-pressure section. The housing member is configured with a high-pressure-side port and an oil separator. An outlet opening of the port and an oil outlet are configured at diametrical ends of the oil separator. The oil outlet is arranged in the lowermost section of the oil separator in a direction of the effect of gravity and is hydraulically connected to an inlet of the flow duct. The housing member is configured with the inlet chamber such that the high-pressure-side port is able to be arranged with the axis within the inlet chamber irrespective of the arrangement of the oil outlet.
