摘要： A scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll. The relationship between the involute surfaces of the spiral wraps of the two scrolls and the dimensions, dimensional tolerance, and assembly standards of the rotation-preventing mechanism are determined so that the median value of an allowable angle of rotation (φ) agrees with an upright position of the orbiting scroll.

摘要： A scroll compressor that suffers no decrease in compression performance due to leakage resulting from a twisting assembly error is provided. This scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll. The relationship between the involute surfaces of the spiral wraps of the two scrolls and the dimensions, dimensional tolerance, and assembly standards of the rotation-preventing mechanism are determined so that the median value of an allowable angle of rotation (φ) agrees with an upright position of the orbiting scroll.

摘要： The present invention provides a screw compressor in which an oil path is provided within the casing body such that the oil for sealing gaps in the compression chamber and lubricating the bearings is circulated to the vicinity of the low pressure side, allowing the compressor to have high adiabatic efficiency and high volumetric efficiency. The present invention also provides a screw compressor in which an oil path is provided in the screw bore outer circumferential portion of the casing body to prevent contact between the screw rotor and the screw bore portion of the casing body. The present invention also provides a screw compressor which includes a heat sink to increase the heat transfer area for exchanging heat between the oil and refrigerant gas or liquid refrigerant, thereby achieving increased resistance to returned liquid refrigerant.

摘要： Provided is a two-shaft rotary pump which is capable of improving reliability and operation efficiency by preventing an exhaust gas from flowing backward into a pump as much as possible, preventing the interior of the pump form being excessively compressed as much as possible, and suppressing temperature rise in the pump. A two-shaft rotary pump in which two rotating shafts (20, 20) provided with rotors (30, 30) are supported by bearings, such that the two rotors (30, 30) are rotated in a noncontact manner with a small clearance kept therebetween and the two rotors (30, 30) are rotated in a noncontact manner with a small clearance between an inner surface of a cylinder (50) and the two rotors, and a gas sucked into the cylinder (50) and compressed is discharged from the cylinder (50), wherein an escape hole capable of letting a part of the compressed gas escape is provided in at least one of end wall portions (52) constituting both ends of the cylinder (50) and opened in the axial direction of the rotating shafts (20, 20).
