Compressor comprising a piston dummy

Abstract

A compressor comprising a liquid acting as piston that is displaceable in the piston compartment is described. According to the invention, a piston dummy ( 5 ) that can be displaced with the liquid ( 3 ) is arranged in the liquid. This piston dummy ( 5 ) is preferentially designed in such a manner that upon reaching the top dead centre it brings about an acceleration of the liquid ( 3 ) in the ring gap defined by said piston dummy and the piston chamber wall.

1 . A compressor, comprising a liquid displaceable in a the piston chamber acting as piston, characterized in that in the liquid a piston dummy that can be displaced with said liquid is arranged. 
     
     
         2 . The compressor as claimed in  claim 1 , characterized in that the piston dummy is designed in such a manner that upon reaching top dead centre it causes an acceleration of the liquid in a ring gap defined by said piston dummy and a the piston chamber wall. 
     
     
         3 . The compressor as claimed in  claim 1 , characterized in that a bottom of the piston dummy is designed in such a manner that the liquid is held or accelerated in the region of the piston dummy bottom. 
     
     
         4 . The compressor according to  claim 1 , characterized in that the piston dummy is comprises one or multiple pieces. 
     
     
         5 . The compressor according to  claim 1 , characterized in that the liquid at least partially is an ionic liquid.
