Suction valve and reciprocating compressor having the same

Abstract

Disclosed is a reciprocating compressor comprising: a motor part mounted inside a hermetic container for generating a rotational driving force; and a compression part for sucking a refrigerant into a cylinder and discharging the refrigerant through a suction channel and a discharge channel of a head accordingly as a piston is linearly reciprocated in the cylinder by the rotational driving force of the motor part, in the reciprocating compressor, a suction valve seat is included, the suction valve seat composed of: an open/close portion fixed between the cylinder and the head of the compression part and opposite to the suction channel for opening and closing the suction channel; and an elastic portion formed as a curved line at the periphery of the open/close portion for elastically supporting the open/close portion.

1 . A reciprocating compressor comprising: 
 a motor part mounted inside a hermetic container for generating a rotational driving force; and    a compression part for sucking a refrigerant into a cylinder and discharging the refrigerant through a suction channel and a discharge channel of a head accordingly as a piston is linearly reciprocated in the cylinder by the rotational driving force of the motor part,    in the reciprocating compressor, a suction valve seat is included, the suction valve seat composed of: an open/close portion fixed between the cylinder and the head of the compression part and opposite to the suction channel for opening and closing the suction channel; and an elastic portion formed as a curved line at the periphery of the open/close portion for elastically supporting the open/close portion.    
   
   
       2 . The reciprocating compressor of  claim 1 , wherein the suction valve seat is provided with an elastic portion cut as a spiral shape at the periphery of the open/close portion for elastically supporting the open/close portion.  
   
   
       3 . The reciprocating compressor of  claim 1 , wherein the suction valve seat is provided with a cut inner part except the open/close portion.  
   
   
       4 . The reciprocating compressor of  claim 3 , wherein the suction valve seat is provided with an elastic portion cut as a spiral shape at the periphery of the open/close portion for elastically supporting the open/close portion.  
   
   
       5 . The reciprocating compressor of  claim 1 , wherein the suction valve seat is abrasion-resistance processed in order to reduce an abrasion between the end of the open/close portion and the head.  
   
   
       6 . A suction valve comprising: 
 an open/close portion formed as a thin plate of a predetermined shape for opening and closing a suction channel through which gas is sucked into a cylinder; and    an elastic portion extended from the open/close portion as a curved line to cover the open/close portion for elastically supporting the open/close portion.
