Compressor

Abstract

The present invention intends to provide a compressor having a mounting construction which can be mounted to the mounted body even in a limited setting space in the vehicle. That is, in the compressor comprised of a bore housing 10 , plural pistons 19 , a driving shaft 12 , and a side housing 20 , the side housing 20 has at least two main mounting portions 50 each having a fitting portion which extends in a tangential direction of the side housing and into which a main fixing bolt means 53 is inserted; and the bore housing 10 has at least one sub mounting portion 60 having a fitting portion which extends in a tangential direction of the bore housing and into which a sub fixing bolt means 63 is inserted.

What is claimed is:  
     
         1 . A compressor comprising a bore housing including plural cylinder chambers spaced in a circumferential direction thereof, plural pistons each being slidably inserted into the cylinder chamber, a driving shaft disposed coaxialy with the bore housing and a side housing including a driving means driven by the driving shaft to drive the pistons, 
 characterized by that 
 the side housing has, on an outer peripheral surface thereof, at least two main mounting portions each having an inserting portion which extends in a tangential direction of the side housing and into which a main fixing bolt means is inserted; and  
 the bore housing has, on an outer peripheral surface thereof, at least one sub mounting portions having a fitting portion which extends in a tangential direction of the bore housing and into which a sub fixing bolt means is fitted.  
   
     
     
         2 . A compressor according to    claim 1   , wherein the side housing has a cap shape including a cylindrical portion and lid portion, two main mounting portions being respectively formed at a top portion and a bottom portion in a circumferential direction, and at a boundary portion between the cylindrical portion and the lid portion in the axial direction.  
     
     
         3 . A compressor according to    claim 2   , wherein each of the main mounting portions protrudes radially outwardly from the outer peripheral surface of the side housing, having a predetermined width in an axial direction thereof, and having a predetermined length in a tangential direction thereof; and the fitting portion extends in a thickness direction of the sub mounting portion.  
     
     
         4 . A compressor according to    claim 1   , wherein the bore housing has a cylindrical shape; one sub mounting portion protrudes radially outwardly from the outer peripheral surface of the bore housing of cylindrical shape, having a predetermined width in an axial direction thereof, and having a predetermined thickness in a tangential direction thereof; and the inserting portion extends in the thickness direction of the sub mounting portion.  
     
     
         5 . A compressor according to    claim 4   , wherein the sub mounting portion is shifted from a top portion of the bore housing in the circumferential direction thereof.  
     
     
         6 . A compressor according to    claim 5   , wherein the fitting portion of the sub mounting portion is comprised of an inserting hole of circular shape in section; the sub fixing bolt means is comprised of a bushing abutting to the sub mounting portion at one portion, and abutting to the outer peripheral surface of the cylinder block at other portion, and a bolt penetrating the bushing and the sub mounting portion and being screwed into the mounted body.  
     
     
         7 . A compressor according to    claim 5   , wherein the fitting portion of the sub mounting portion is comprised of a U-shaped fitting groove; the sub fixing bolt means is comprised of a stud bolt extending from the mounted body and protrudes from the fitting groove, and a nut screwed with a protruded portion of the stud bolt.  
     
     
         8 . A compressor according to    claim 5   , wherein the fitting portion of the sub mounting portion is comprised of a inserting hole of circular shape in section; the sub fixing bolt means is comprised of a bolt extending from the mounted body and having a head portion formed a tapered female screw portion fitted in the inserting hole, and a tapered male screw portion for enlarging the tapered female portion to be abutted to the sub mounting portion.  
     
     
         9 . A compressor according to    claim 1   , wherein the sub mounting portion protrudes radially outwardly from the outer peripheral surface of the bore housing, having a predetermined width in an axial direction thereof, and having a predetermined length in a tangential direction thereof; and the fitting portion extends in a longitudinal direction of the sub mounting portion.  
     
     
         10 . A compressor according to    claim 9   , wherein the fitting portion of the sub mounting portion is comprised of a sliding hole of circular shape in section in which a sleeve is mounted.
