Compressor

Abstract

A compressor for compressing a refrigerant comprising a cylinder block, a cylinder cover ( 12 ) and a valve plate ( 10 ) which is interposed between the cylinder block and the cylinder cover ( 12 ), said valve plate ( 10 ) being connected to the cylinder cover ( 12 ) and/or to the cylinder block without redundancy in the sealing plane.

1 . A compressor for compressing refrigerant comprising a cylinder block, a cylinder cover and a valve plate, said valve plate being interposed between the cylinder block and the cylinder cover, wherein
 the valve plate is connected to the cylinder cover and/or is connected to the cylinder block, or respectively fastened thereto.   
     
     
         2 . The compressor according to  claim 1 , wherein
 the valve plate is connected to the cylinder cover and/or to the cylinder block by means of a connecting element, in particular a screw, or respectively is fastened thereto.   
     
     
         3 . The compressor according to  claim 1 , wherein
 the valve plate comprises a thread.   
     
     
         4 . The compressor according to  claim 1 , wherein
 the cylinder cover has a suction volume and a pressure volume, wherein a support element, in particular approximately column-shaped, is arranged in the suction volume or in the pressure volume, the support element extending from an outer wall of the cylinder cover towards the valve plate.   
     
     
         5 . The compressor according to  claim 4 , wherein
 the support element has a recess, which extends from the outer wall of the cylinder cover in the direction of the valve plate, the recess being provided for receiving the connecting element.   
     
     
         6 . The compressor according to  claim 1 , wherein
 the valve plate has one or more suction disks and/or one or more pressure disks, which are formed in a ring valve design.   
     
     
         7 . The compressor according to  claim 1 , wherein
 the connection of the valve plate to the cylinder cover and/or to the cylinder block is effected in the region of a pressure nest, or respectively a pressure unit, of the valve plate.   
     
     
         8 . The compressor according to  claim 1 , wherein
 the valve plate has a lift catch, which limits the lift of a pressure disk away from the valve plate.   
     
     
         9 . The compressor according to  claim 8 , wherein
 a gap is arranged between the lift catch and the cylinder cover.   
     
     
         10 . The compressor according to  claim 1 , wherein
 the valve plate is pressed together with the cylinder cover against the cylinder block by fastening elements, in particular fastening screws in regions, in which it does not cover any cylinder bores arranged in the cylinder block.
