Suction valve assembly for alternative compressor

Abstract

The present invention refers to a suction valve assembly for alternative compressors. Said suction valve assembly comprises at least two suction valves ( 3 ) independent from one another and disposed at one same blade ( 1 ), wherein each of said suction valves ( 3 ) comprises a functional edge ( 4 ) intended for a sole suction orifice ( 21 ) of the valve plate. Said suction valves ( 3 ) are separated from one another by at least one through slit ( 13 ).

1 . Suction valve assembly for alternative compressor intended for a compressor chamber provided with at least two orifice suctions and comprising at least one blade ( 1 ) provided with at least one through orifice ( 11 ); said suction valve assembly being CHARACTERIZED in that it comprises:
 at least two independent suction valves ( 3 ) disposed at one same blade ( 1 );   each of said two suction valves ( 3 ) comprising a functional edge ( 4 ) intended for a single suction orifice ( 21 ) of the valve plate ( 2 );   said suction valves ( 3 ) being separated from one another by at least one through slit ( 13 ).   
     
     
         2 . Suction valve assembly, in accordance with  claim 1 , CHARACTERIZED in that one of the functional edges ( 4 ) comprises a free of its respective valve ( 3 ). 
     
     
         3 . Suction valve assembly, in accordance with  claim 1 , CHARACTERIZED in that at least one of said suction valves ( 3 ) is asymmetric. 
     
     
         4 . Suction valve assembly, in accordance with  claim 1 , CHARACTERIZED in that the functional edges ( 4 ) of suction valves ( 3 ) and said through orifices ( 11 ) of blade ( 1 ) are disposed at a same area ( 5 ) defined by a single compression chamber. 
     
     
         5 . Suction valve assembly, in accordance with  claim 4 , CHARACTERIZED in that said suction valves ( 3 ) are disposed between the suction through orifices ( 11 ).
