Compressor

Abstract

A compressor for compressing coolant circulating in a cooling circuit, wherein the compressor includes at least one receiving element for spring elements carrying a compressor/motor unit. With its casing element, this receiving element protrudes past a sump height of a lubricant sump in a vertical direction, which lubricant sump forms in the housing interior in an operating state of the compressor. Because lubricant is constantly distributed throughout the entire housing interior in the operating state—caused by the motion of the movable parts of the compressor—lubricant also collects within a receiving volume of the receiving element, where it forms a level that is clearly above the sump height of the lubricant sump as viewed in a vertical direction. As a result, a damping of the spring elements is achieved by the lubricant, and therefore without the inclusion of additional means elements.

1 . A compressor for compressing coolant circulating in a cooling circuit, comprising
 a compressor housing enclosing a housing interior of the compressor,   a compressor/motor unit which comprises at least one piston, which moves in a cylinder, and a motor,   at least one spring element, preferably multiple spring elements, via which spring element the compressor/motor unit is attached in an elastically mounted manner to a mounting region of the compressor housing, preferably to a base region of the compressor housing, and   at least one receiving element arranged on the mounting region for the at least one spring element, preferably one receiving element for one spring element each, wherein the respective spring element is accommodated in the receiving element,   wherein the receiving element comprises a base element, which is connected to the mounting region and from which the spring element protrudes in a vertical direction, a casing element, which casing element surrounds the spring element in a sleeve-like manner, and a receiving volume bounded by the base element and the casing element, in order to enable a collection of lubricant in the receiving volume, so that a section of the spring element that is arranged in the receiving volume is enveloped by lubricant in the operating state of the compressor,   wherein   the casing element protrudes past a sump height of a lubricant sump in the vertical direction, which lubricant sump forms in the housing interior in the operating state of the compressor.   
     
     
         2 . The compressor according to  claim 1 , wherein a minimum clear inner diameter of the casing element is larger than a maximum outer diameter of the spring element. 
     
     
         3 . The compressor according to  claim 1 , wherein, in an operating state of the compressor, in which operating state the at least one spring element is loaded only with the weight of the compressor/motor unit, at least the first three spring coils, preferably 50% of the spring coils, particularly preferably more than 70% of the spring coils, of the spring element lie within the receiving volume of the respective receiving element. 
     
     
         4 . The compressor according to  claim 3 , wherein a spring travel extends between at least two of the spring coils of the respective spring element that lie within the receiving volume in the aforementioned operating state of the compressor. 
     
     
         5 . The compressor according to  claim 1 , wherein the receiving element comprises a rod-like spring holder protruding from the receiving element in the vertical direction, via which spring holder the spring element is connected by the inner side thereof to the receiving element in a force fit. 
     
     
         6 . The compressor according to  claim 5 , wherein the casing element protrudes past the spring holder of the receiving element in a vertical direction. 
     
     
         7 . The compressor according to  claim 1 , wherein the casing element of the receiving element is embodied to be elastic. 
     
     
         8 . The compressor according to  claim 1 , wherein at least the casing element, but preferably the entire receiving element, is made of an elastomer, particularly preferably of a fluoroelastomer. 
     
     
         9 . The compressor according to  claim 1 , wherein a clear inner diameter of the casing element increases monotonically as viewed in the vertical direction. 
     
     
         10 . The compressor according to  claim 9 , wherein the casing element comprises a first vertical section and a second vertical section, wherein the first vertical section and the second vertical section each extend in the vertical direction, wherein a first clear inner diameter of the casing element is constant in the region of the first vertical section and wherein the second vertical section the casing element comprises a diameter expansion. 
     
     
         11 . The compressor according to  claim 9 , wherein the casing element, as viewed in a cross-section running parallel to the vertical direction, has, at least sectionwise, the shape of a circular arc, wherein a circle corresponding to said circular arc has its center outside of the receiving element.
