Abstract
According to the invention, a compressor having a screw connection portion formed at a fitting portion of the housing is provided. As no through bolt, etc., for connecting a plurality of parts of the housing is used, the diameter of the housing becomes small. However, in a case that a suction port and discharge port do not align with some objective equipment, a mounting means able to slide on the housing and adjust the positions of mounting brackets at least in the direction of rotation is added.
Claims7
A compressor comprising:
- a housing rotatably supporting a shaft and constituted from a plurality of parts aligning in the axial direction of said shaft and integrated with each other;
- a fitting portion provided between an end portion of one part of said housing and an end portion of another one part adjacent to said one part;
- and
- a screw connection portion formed on an inner and outer contact surfaces of said fitting portion;
- and wherein
- parts of said housing are connected and integrated with each other only by said screw connection portion formed with said fitting portion.
5 A compressor as set forth in claim 1, wherein all of said mounting bracket for securing said housing to some objective equipment is formed integrally with said one part of said housing on the side having a suction port and a discharge port.
6 A piston-type variable capacity compressor as set forth in claim 1, further comprising:
- a drive plate rotating by being connected with and supported by said shaft and able to tilt with respect to said shaft;
- a shoe holding plate supported by said drive plate through a drive thrust bearing forming a roller bearing and thereby taking the same tilt angle, but prevented from rotating;
- a plurality of shoes engaging with a plurality of shoe guide grooves formed in radial direction at a peripheral part of said shoe holding plate and able to slide in the radial direction;
- a plurality of pistons directly connected with said shoes and engaging in reciprocating motion, inserted in cylinder bores to suck in and compress a fluid, and preventing rotation of said shoe holding plate;
- and
- means for changing the tilt angle of said drive plate and said shoe-holding plate to change a discharge capacity.
