Refrigerant compressor arrangement

Abstract

The invention concerns a refrigerant compressor arrangement with a compressor unit ( 2 ) supported in a case by means of springs ( 12 ) and comprising at least one bolt ( 26 ) with a bolt head ( 25 ), a holder ( 23 ) being arranged between the compressor unit ( 2 ) and at least one spring ( 12 ), the holder ( 23 ) having in its front a recess, in which the bolt head ( 25 ) engages, and which is connected to the spring ( 12 ). It is endeavoured to reduce the noise generation during operation of the refrigerant compressor arrangement. For this purpose, the bolt head ( 25 ) is arranged in the recess ( 24 ) with lateral clearance ( 34 ).

1 . A refrigerant compressor arrangement with a compressor unit supported in a case by means of springs and comprising at least one bolt with a bolt head, a holder being arranged between the compressor unit and at least one spring, the holder having in its front a recess, in which the bolt head engages, and which is stuck together with the spring, wherein the bolt head is arranged in the recess with lateral clearance. 
     
     
         2 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the size of the lateral clearance is in the range from 0.2 to 0.5 mm. 
     
     
         3 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the compressor unit rests on the front side and the recess has a depth, which is larger than an extension of the bolt head in the depth direction. 
     
     
         4 . The refrigerant compressor arrangement in accordance with  claim 3 , wherein a difference between the depth of the recess and the extension of the bolt head has a size in the range from 0.4 to 1 mm. 
     
     
         5 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the holder is made of a plastic material that interacts smoothly with the compressor unit, and the holder and the compressor unit bear on each other with smooth surfaces. 
     
     
         6 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the bolt head has an undercut in its circumferential surface, behind which projections directed inwardly in the recess engage the holder. 
     
     
         7 . The refrigerant compressor arrangement in accordance with  claim 6 , wherein the recess is surrounded by a circumferential wall, in which at least two slits extending from the inside to the outside are arranged. 
     
     
         8 . The refrigerant compressor arrangement in accordance with  claim 6 , wherein in the axial direction the projections have a smaller extension than the undercut. 
     
     
         9 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the holder is made as a hollow body. 
     
     
         10 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the front side is formed on a side of a front side wall, which has several recesses on the bottom side opposite to the front side. 
     
     
         11 . The refrigerant compressor arrangement in accordance with  claim 10 , wherein the recesses are open in the direction of the circumferential wall of the holder. 
     
     
         12 . The refrigerant compressor arrangement in accordance with  claim 1 , wherein the holder is made of an electrically isolating plastic material.
