Compressor with compact screw connected housing and adjustable mounting means

A compressor comprising:

• a housing rotatably supporting a shaft and constituted from first and second parts aligned in an axial direction of said shaft and integrated with each other;
• a fitting portion comprised of inner and outer housing portions, wherein the inner and outer housing portions are respectively formed at an end portion of said first part of said housing and an end portion of said second part;
• a threaded screw connection portion comprised of inner and outer screw portions directly and respectively formed on inner and outer contact surfaces of said fitting portion, wherein the first and second parts of said housing are connected and integrated with each other only by said threaded screw connection portion formed with said fitting portion;
• a drive plate rotating by being connected with and supported by said shaft and able to tilt with respect to said shaft at a tilt angle;
• a shoe holding plate supported by said drive plate through a drive thrust bearing forming a roller bearing, wherein the shoe holding plate tilts with respect to said shaft at the tilt angle of the drive plate and is 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.

• 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;
• a plurality of pistons inserted in cylinder bores to suck in and compress a fluid and preventing rotation of said shoe-holding plate;
• a mechanism for converting tilted rotary motion of said drive plate to reciprocating motion of said pistons;
• and
• a slide link mechanism comprised of a plurality of pins and a plurality of guide grooves with which the pins engage is provided at a position away from the axial center of said shaft for connecting said shaft and said drive plate, as a means for changing the tilt angle of said drive plate to change a discharge capacity.

A compressor comprising:

• a housing, wherein the housing supports a rotary shaft, and the housing is constituted by first and second parts, which are axially aligned with an axis of the rotary shaft, wherein the first and second housing parts are fastened to one another only by a threaded screw section of the housing, in which inner threads formed directly on an inner part of one of the first and second housing parts are engaged with outer threads formed directly on an outer part of the other of the first and second housing parts;
• a first mounting bracket for attaching the compressor to a fixed structure;
• a second mounting bracket for attaching the compressor to the fixed structure;
• wherein:
• the first mounting bracket is attached to the first housing part, and the position of the first mounting bracket on the first housing part is adjustable;
• the second mounting bracket is integrated with and immovably fixed to the second housing part;
• and
• the first mounting bracket is constructed and arranged to rotate with respect to said housing at least in the direction of shaft rotation to adjust the position of the first mounting bracket with respect to the first housing part.
