摘要： A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.

摘要： When a driving shaft rotates, a piston (9) revolves around the driving shaft in a cylinder room (6a) with supported by a swing bush (32) as a supporting point through a blade (31). Discharge ports (22) are formed in a front head (7) and a rear head (8) respectively and are disposed to be located in the proximity of the blade (31) and to communicate with a high pressure room. A semicircular portion of the discharge port (22) overlaps with the swing bush (32) and the cylinder (6). A pair of upper and lower cut parts (41) are each formed by cutting away an outer peripheral edge of the swing bush (32) and an inner peripheral edge of the cylinder (6) which are overlapped with the discharge port (22).

摘要： A single-screw compressor includes a screw rotor including a spiral groove, a casing, and a gate rotor. The gate rotor includes a plurality of radial gates configured to mesh with the spiral groove. A clearance between one of the gates disposed in the spiral groove and a wall surface of a discharge side portion of the spiral groove is larger than a clearance between the gate disposed in the spiral groove and a wall surface of a suction side portion of the spiral groove. The wall surface of the discharge side portion of the spiral groove is a portion extending from a predetermined position of the spiral groove at a certain point in a compression phase to the terminal end of the spiral groove. The wall surface of the suction side portion of the spiral groove being a portion other than the discharge side portion.
