Vane structure for compressor

Abstract

A vane structure for a compressor comprises: a Z-plate located in a cylinder assembly for dividing an inner space of the cylinder assembly into a plurality of compression spaces and notated by a driving unit to suck, compress, and discharge fluid; and vanes undergoing reciprocating movements by being contacted to both surfaces of the Z-plate for dividing the respective compression space into a suction area and a compression area, wherein the vane includes a vane roller which is rolling contacted to the Z-plate to reduce a friction resistance between the Z-plate and the vane, and thereby an abrasion can be minimized, a noise generation can be reduced, life spans of components can be increased, and a reliability of the compressor can be improved.

1 . A vane structure for a compressor including a cylinder assembly having a suction passage and a discharge passage, a Z-plate dividing an inner space of the cylinder assembly into a plurality of compression spaces, and sucking, compressing and discharging a fluid while being rotated by a driving unit, and vanes being in contact with both sides of the Z-plate to make a reciprocal movement, and dividing each compression space into a suction area and a compression area, 
 wherein the vane has a vane roller being in rolling-contact with the Z-plate.    
     
     
         2 . The vane structure of  claim 1 , wherein the vane includes a vane plate reciprocally moved along both sides of the Z-plate and a vane roller provided at the vane plate and being in a rolling-contact with the Z-plate.  
     
     
         3 . The vane structure of  claim 2 , wherein the vane plate includes a roller receiving hole into which the vane roller is inserted and mounted.  
     
     
         4 . The vane structure of  claim 3 , wherein the vane roller is formed as a bar type with the same diameter wholly, and the roller receiving hole is formed in a hole structure having the same inner diameter.  
     
     
         5 . The vane structure of  claim 3 , wherein an opened portion of the roller receiving hole so that the vane roller comes in contact with the Z-plate therethrough is smaller than a diameter of the vane roller to prevent the vane roller from releasing.  
     
     
         6 . The vane structure of  claim 3 , wherein at least one of both sides of the roller receiving hole has an opened structure.  
     
     
         7 . The vane structure of  claim 3 , wherein a roller support extended from the vane plate is formed at both sides of the roller receiving hole, and the vane roller can be rotatably supported by the roller support.  
     
     
         8 . The vane structure of  claim 7 , wherein the vane roller is installed at the roller support through a pin member.  
     
     
         9 . The vane structure of  claim 3 , wherein the vane roller is formed in a bar structure with a tapering shape, and the roller receiving hole is formed in a tapering hole structure.  
     
     
         10 . The vane structure of  claim 9 , wherein the vane roller is positioned such that a side with a relatively smaller diameter is directed inward of the cylinder assembly and a side with a relatively greater diameter is directed outward of the cylinder assembly.
