Gas compressor

Abstract

A high-pressure piston compressor ( 1 ) for compressing gas, comprising a vessel ( 4 ) having a vessel chamber ( 8, 23 ) wherein a piston ( 3 ) is guided reciprocally, for compressing a gas in the vessel chamber during operation of the piston compressor, an inlet valve housing ( 17, 29 ) comprising an inlet valve ( 18, 30 ), and an outlet valve housing ( 15, 31 ) comprising an outlet valve ( 16, 32 ), wherein the inlet valve housing and the outlet valve housing are mounted within a portion of the vessel chamber wall ( 14, 28 ), and wherein the portion of the vessel chamber wall encloses the inlet valve housing and the outlet valve housing, such that the portion of the vessel chamber wall generates an isostatic counter-pressure on the inlet valve housing and the outlet valve housing in response to the pressure on the inlet valve housing and the outlet valve housing from the gas in the vessel chamber during operation of the piston compressor.

         14 . A high-pressure piston compressor for compressing gas, comprising:
 a vessel having a vessel chamber and comprising a piston being guided reciprocally for compressing a gas in the vessel chamber during operation of the piston compressor;   an inlet valve housing comprising an inlet valve for controlling a supply of gas into the vessel chamber; and   an outlet valve housing comprising an outlet valve for controlling a discharge of gas out from the vessel chamber;   with said inlet valve housing and said outlet valve housing being mounted within a portion of a vessel chamber wall which elongates into the vessel chamber, and with the portion of the vessel chamber wall enclosing said inlet valve housing and said outlet valve housing, such that the portion of the vessel chamber wall generates an isostatic counter-pressure on said inlet valve housing and said outlet valve housing in response to the pressure on said inlet valve housing and said outlet valve housing from the gas in the vessel chamber during operation of the piston compressor.   
     
     
         15 . The piston compressor according to  claim 14 , further comprising an inlet duct mounted at least partially within the portion of the vessel chamber wall for allowing a supply of gas into the vessel chamber, and with the said inlet valve housing being positioned within the inlet duct and positioned immediately adjacent the vessel chamber. 
     
     
         16 . The piston compressor according to  claim 15 , wherein the inlet duct elongates to the vessel chamber substantially in parallel with an axis of said vessel. 
     
     
         17 . The piston compressor according to  claim 14 , further comprising an outlet duct mounted at least partially within the portion of the vessel chamber wall for allowing a discharge of gas out from the vessel chamber, and with said outlet valve housing being positioned within the outlet duct and positioned immediately adjacent the vessel chamber. 
     
     
         18 . The piston compressor according to  claim 17 , wherein the outlet duct elongates from the vessel chamber substantially in parallel with the axis of said vessel. 
     
     
         19 . The piston compressor according to  claim 14 , wherein the portion of the vessel chamber wall is a block unit detachable from said piston compressor. 
     
     
         20 . The piston compressor according to  claim 19 , wherein said block unit is fastened by a threaded nut, with said block unit being positioned between the threaded nut and the vessel chamber. 
     
     
         21 . The piston compressor according to  claim 14 , wherein the piston compressor is fastened by a plurality of tie rods, elongating in parallel with the axis of said vessel. 
     
     
         22 . The piston compressor according to  claim 14 , wherein the vessel is wound with wire inducing a pre-stress such that the vessel is radially pre-stressed during operation of said piston compressor. 
     
     
         23 . The piston compressor according to  claim 14 , wherein said vessel is enclosed by a force-absorbing press frame. 
     
     
         24 . The piston compressor according to  claim 23 , wherein the force-absorbing press frame is wound with wire inducing a pre-stress such that said vessel is axially pre-stressed during operation of said piston compressor. 
     
     
         25 . The piston compressor according to  claim 14 , wherein said vessel is cooled by cooling bars provided adjacent said vessel.
