Compressor and vane therefor

Abstract

A compressor includes a cylinder assembly which is positioned inside a hermetic vessel having a suction flow path and discharging flow path, a Z-plate for dividing an inner space into a plurality of compression spaces in the cylinder assembly, rotating by a motor part so that gas is sucked, compressed and discharged, and a vane for dividing the respective compression spaces into a suction region and compression region, performing a reciprocating movement being contacted on both surfaces of the Z-plate. In addition, an oil slot for inflowing oil into the cylinder assembly is formed on a side surface of the vane. Therefore, friction generated at a sliding portion inside of the cylinder assembly can be reduced and performance deterioration of the compressor caused by operation noise and friction resistance of the compressor can be prevented.

1 . A compressor, comprising a hermetic vessel; a cylinder assembly disposed in the casing and having a suction flow path and discharging flow path, a Z-plate disposed in the cylinder assembly for dividing an inner space of the cylinder assembly into a plurality of compression spaces in the cylinder assembly, rotating by a motor part so that gas is sucked, a compressed and discharged, and a vane being contacted with the Z-plate for dividing the respective compression spaces into a suction region and compression region, performing a reciprocating movement being contacted on both surfaces of the Z-plate; 
 wherein the vane includes an oil slot formed on one side surface of the vane for inflowing oil to the cylinder assembly.    
     
     
         2 . The compressor of  claim 1 , wherein the oil slot is formed on a side surface of the vane which is positioned in the suction region of the inner space in the cylinder assembly.  
     
     
         3 . The compressor of  claim 2 , wherein the oil slot is formed in the direction that the vane moves.  
     
     
         4 . The compressor of  claim 3 , wherein the plurality of oil slots are formed at an equal interval.  
     
     
         5 . The compressor of  claim 3 , wherein the oil slot is formed having a predetermined length in the direction along from the outer portion to the inner portion of the cylinder assembly so that the outer and inner portions of the cylinder assembly can be communicated when the vane is contacted with the Z-plate and is positioned near a lower dead point.  
     
     
         6 . A vane of a compressor performing a reciprocating movement in the inward and outward directions of a cylinder assembly in which a compression space is formed, and dividing the compression space into a suction region and a compression region, which comprises an oil slot for flowing oil into the cylinder assembly on a side surface.  
     
     
         7 . The vane of  claim 6 , wherein the oil slot is formed on a side surface of the vane which is positioned in an inner space suction region of the cylinder assembly.  
     
     
         8 . The vane of  claim 6 , wherein the oil slot is formed in a direction that the vane moves.  
     
     
         9 . The vane of  claim 6 , wherein the plurality of oil slots are formed at an equal interval.  
     
     
         10 . The vane of  claim 6 , wherein the oil slot is formed having a predetermined length in the direction along from the outer portion to the inner portion of the cylinder assembly so that the outer and inner portions of the cylinder assembly can be communicated along the reciprocating movement of the vane.
