Compressor

Abstract

The invention relates to a compressor ( 1 ) for gaseous and/or cryogenically liquefied media comprising a first compressor piston ( 6 ) and a second compressor piston ( 7 ), which are operatively connected to an eccentric shaft ( 2 ), wherein the second compressor piston ( 7 ) is arranged substantially opposite to the first compressor piston ( 6 ) relative to the eccentric shaft ( 2 ). To solve the object of providing such a compressor with a small space requirement and low construction costs, it is proposed according to the invention for the compressor ( 1 ) to be embodied as an oscillating piston-type compressor, wherein the first compressor piston ( 6 ) is arranged on an eccentric ring ( 4 ), which is effectively connected to the eccentric shaft ( 2 ) and wherein the second compressor piston ( 7 ) is fastened to a pivot lug ( 8 ), which is effectively connected to the eccentric ring ( 4 ).

1 . A compressor for gaseous and/or cryogenically liquefied media comprising a first compressor piston and a second compressor piston, which are operatively connected to an eccentric shaft, wherein the second compressor piston is arranged substantially opposite to the first compressor piston relative to the eccentric shaft, characterized in that the compressor is embodied as an oscillating piston-type compressor, wherein the first compressor piston is arranged on an eccentric ring, which is effectively connected to the eccentric shaft and wherein the second compressor piston is fastened to a pivot lug, which is effectively connected to the eccentric ring. 
   
   
       2 . The compressor according to  claim 1 , characterized in that a fastening lug, to which the first compressor piston is fastened, is embodied on the eccentric ring, wherein the pivot lug of the second compressor piston is arranged on the eccentric ring in an articulated manner in the area of the fastening lug of the first compressor piston. 
   
   
       3 . The compressor according to  claim 1 , characterized in that the pivot lug is embodied as a bow-shaped component, which encompasses a cross-plate, to which the second compressor piston is fastened and two substantially ring-shaped side parts, which are 
     spaced apart from one another, wherein a receiving space for the eccentric ring is embodied between the side parts. 
   
   
       4 . The compressor according to  claim 3 , characterized in that a receiving bore for a pivot pin is embodied on the side parts. 
   
   
       5 . The compressor according to  claim 4 , characterized in that a through hole for the pivot pin is embodied on the eccentric ring. 
   
   
       6 . The compressor according to  claim 5 , characterized in that the pivot pin is supported in the through hole of the eccentric ring via a bush. 
   
   
       7 . The compressor according to  claim 1 , characterized in that the compressor is embodied as a two-stage compressor, wherein the first compressor piston forms the input stage and the second compressor piston forms the output stage of the compressor. 
   
   
       8 . The compressor according to  claim 7 , characterized in that the first compressor piston is arranged in a first compressor cylinder and the second compressor piston is arranged in a second compressor cylinder, wherein the output of the first compressor cylinder is connected to the input of the second compressor cylinder.
