Compressor, and vehicle compressed air system with a compressor of this type

Abstract

A compressor for providing compressed air for a vehicle compressed air system has an inlet chamber formed by an inlet chamber wall and provided with an inlet opening for taken-in air, and an outlet chamber defined by an outlet chamber wall and provided with an outlet opening for air compressed by the compressor. Furthermore, the compressor has a heat flow reduction device which is designed to reduce at least one of a heat flow from a component, connected to the inlet chamber wall, of the compressor to the taken-in air in the inlet chamber and a heat flow from the compressed air in the outlet chamber to a component, connected to the outlet chamber wall, of the compressor.

 a connector portion for the inlet chamber and the outlet chamber,   a compression space housing configured such that the sucked-in air is compressed therein, and   a valve plate between the connector portion and the compression space housing,   wherein the valve plate forms a portion of the inlet chamber wall and the outlet chamber wall, and   wherein the heat flow reduction device has a first thermal insulation material at least between one of the inlet chamber wall and the outlet chamber wall on one side and the valve plate on the other side.   
     
     
         6 . The compressor of  claim 5 , wherein the first thermal insulation material is provided between both the inlet chamber wall and the outlet chamber wall on one side and the valve plate on the other side. 
     
     
         7 . The compressor of  claim 2 , further comprising:
 a connector portion for the inlet chamber and the outlet chamber,   a compression space housing configured such that the sucked-in air is compressed therein, and   a valve plate between the connector portion and the compression space housing, and   a first contact surface being formed between the inlet chamber wall and the outlet chamber wall on one side and the valve plate on the other side,   wherein the heat flow reduction device having a first cutout in at least one of the inlet chamber wall, the outlet chamber wall and the valve plate next to the first contact surface, such that the first cutout is configured to form a second air gap next to the first contact surface.   
     
     
         8 . The compressor of  claim 1 ,
 the compressor having a compression space housing which is configured such that the sucked-in air is compressed therein, and   the heat flow reduction device having a second thermal insulation material between at least one of the inlet chamber wall and the outlet chamber wall on one side and the compression space housing on the other side.   
     
     
         9 . The compressor of  claim 7 , further comprising:
 a compression space housing configured such that the sucked-in air is compressed therein, and   a second contact surface being formed between the compression space housing on one side and the inlet chamber wall and the outlet chamber wall on the other side,   wherein the heat flow reduction device has, in at least one of the inlet chamber wall, the outlet chamber wall and the compression space housing, next to the second contact surface, a second cutout which is configured such that a third air gap is formed next to the second contact surface.   
     
     
         10 . The compressor of  claim 1 , further comprising:
 a connector portion for the inlet chamber and the outlet chamber,   a compression space housing configured such that the sucked-in air is compressed therein, and   a valve plate between the connector portion and the compression space housing,   wherein, as the heat flow reduction device, the valve plate has a region which projects from the connector portion and the compression space housing.   
     
     
         11 . The compressor of  claim 10 , wherein the region which projects from the compression space housing is configured to act as a cooling fin. 
     
     
         12 . The compressor of  claim 1 , wherein a cross-sectional area of the inlet chamber in a region of the inlet valve corresponding approximately to a cross-sectional area of a component of the inlet valve in the inlet chamber is configured as the heat flow reduction device. 
     
     
         13 . The compressor of  claim 1 , wherein a cross-sectional area of the outlet chamber in a region of the outlet valve corresponding approximately to a cross-sectional area of a component of the outlet valve in the outlet chamber is configured as the heat flow reduction device.
