Problems solved by technology

These refrigerant compressors, especially when they are reciprocating, have pulsations that are transmitted from the output chamber into the adjacent piping; this on the one hand leads to unwanted noise in the piping , on the other hand, the piping is subjected to mechanical stress due to pressure peaks

Embodiment Construction

[0041] The volumetric compressor designed according to the present invention is a piston compressor, and its compressor cylinder 10 is partially shown by Fig. 1; A cylinder head 18 is arranged thereon, which is sealed by means of a gasket 16;

[0042] Furthermore, the cylinder head 18 is provided with a short connecting pipe 28, which is preferably arranged in the cover 30 of the cylinder head 18, so as to form an outlet channel 32 through which the compressed refrigerant can flow from the outlet chamber 24 out and into the fitting 34.

[0043] This nipple 34 can be placed on the connecting surface 36 of the short connecting pipe 28 and can be mounted thereon.

[0044] As shown in Fig. 1 to Fig. 6, the whole of the damping part is represented by a mark 40; in order to damp the pulsation in the refrigerant flow flowing out from the output chamber 24, the damping part 40 with an inlet baffle 42 and an outlet baffle 44 The connecting channel 32 is inserted into the short connec...

Abstract

To improve a refrigerant compressor, in particular, displacement compressor, comprising a compressor housing enclosing an outlet chamber and an outlet passage leading from the outlet chamber to an external high pressure connection, such that the pulsations in it are damped as much as possible it is suggested that a pulsation damping element be inserted into the outlet passage of the compressor housing following the outlet chamber, that the pulsation damping element have an inlet baffle which faces the outlet chamber and extends over a cross section of the outlet passage and, located opposite thereto, an outlet baffle which extends over the cross section of the outlet passage, that at least one reflection chamber be provided between the inlet baffle and the outlet baffle and that the inlet baffle and the outlet baffle each have at least one passage which faces a reflection surface on the respectively other baffle.

Description

technical field [0001] The present invention relates to a refrigerant compressor, in particular to a positive displacement compressor, such as a piston compressor or a scroll compressor, comprising a compressor cylinder with an output closed by the compressor cylinder cavity, and the output channel leading from the output cavity to the external high-pressure pipe joint. Background technique [0002] Refrigerant compressors of this type are known from the prior art. These refrigerant compressors, especially when they are reciprocating, have pulsations that are transmitted from the output chamber into the adjacent piping; this on the one hand leads to unwanted noise in the piping , on the other hand, the piping is subjected to mechanical stress due to pressure peaks. Contents of the invention [0003] It is therefore the object of the present invention to improve refrigerant compressors of the general type in such a way that the pulsations therein are damped to the lowest ...
