| A screw compressor (1) includes a slide valve (60) for changing a compression ratio. A valve body (65) of the slide valve (60) includes a sealing projection (66) extending along a rear end surface (74) thereof. In a slide valve housings (31) of a casing (10), the sealing projection (66) separates a low-pressure space (S1) and a high-pressure space (S2) from each other when being in slidable contact with a slidable-contact curved surface (32) of the casing (10). A refrigerant pressure in the low-pressure space (S1) is always applied on the entire nonslidable-contact surface (77) in the valve body (65). Thus, a force that pushes the valve body (65) toward a screw rotor (40) is constant, independently of the position of the slide valve (60), thereby decreasing a change of a clearance between a front surface (71) of the valve body (65) and the screw rotor (40). | ||||||

| 図ローラ32のローラ内周面32bとクランク軸31の偏心部31aの偏心部外周面31bとの第1の軸受すきまと、クランク軸31の偏心部31aの直径との比を、11/10000から20/10000とすることによって、高圧部と低圧部の差圧による差圧力により、ローラ32をシリンダ内壁面30aに軽く押し付けることができ、運転時最小すきまWを極小化するとともに、差圧力のみでシリンダ内壁面30aに接触させることができるので、大きな摺動ロスにならない。そのため、磨耗や焼き付きなどの信頼性面の低下を抑制しながら、運転時最小すきまWからの漏れを低減し、高効率化を図ることができ、その結果、信頼性面を悪化させずに運転時最小すきまWからの漏れ損失を徹底的に低減し、かつ摺動損失も増加させずに、圧縮機の更なる高効率化を図る。 | ||||||

| PROBLEM TO BE SOLVED: To provide a screw compressor for preventing degradation of the efficiency of the compressor caused by the simultaneous opening of two adjacent helical grooves to a discharge port. SOLUTION: The screw compressor (1) includes a screw rotor (40), a casing (10) for housing the screw rotor (40) and having the discharge port formed in the inner peripheral surface of the casing, and gate rotors (50) having gates (51, 51, ...) meshing with helical grooves (41) of the screw rotor (40). A compression chamber (23) formed by the screw rotor (40), the casing (10), and the gate rotors (50) compresses gas and discharges the compressed gas from the discharge port. The discharge port is divided into a first port (74b) in which one helical groove (41) opens and a second port (75b) in which the other helical groove (41) opens when the two adjacent helical grooves (41, 41) out of the helical grooves (41) accompanying rotation of the screw rotor (40) open to the discharge port.

| <P>PROBLEM TO BE SOLVED: To prevent an aged performance deterioration of a single screw compressor by preventing deformation of a gate which meshes with a spiral groove of a screw rotor, and reducing wear of the gate. <P>SOLUTION: In a single screw compressor, a gate rotor assembly (60) is constituted by a gate rotor (50) and a gate rotor supporting member (55). In the gate rotor assembly (60), each gate (51) is supported by a gate supporting member (57) from the back side. In each gate (51), a pressure introduction passage (52) which penetrates through each gate (51) in thickness direction thereof is formed. Further, a back pressure space (65) is formed on a back side of each gate (51). The back pressure space (65) communicates with a space at front side of the gate (51) via the pressure introduction passage (52). Thus, an internal pressure of the back pressure space (65) becomes nearly equal to a coolant pressure acting on the front of the gate (51). <P>COPYRIGHT: (C)2009,JPO&INPIT | ||||||

| <P>PROBLEM TO BE SOLVED: To compatibly improve both of efficiency and reliability of a screw compressor by narrowing a gap between a slide valve and a screw rotor while avoiding contact of both components. <P>SOLUTION: Inside a casing 10 of a single-screw compressor, a slide valve 70 is disposed to a side of a screw rotor 40. A valve element part 60 of the slide valve 70 is formed in a pillar shape, and an opposing face 66, which is formed as an arc face faces the slide valve 70. A front step portion 64 and a rear step portion 65 are formed on the opposing face 66 of the valve element part 60. Dynamic pressure is created by refrigerant gas injected at the step portions 64, 65. Rotation of the valve element part 60 is controlled by the dynamic pressure created at the step portions 64, 65 acting on the valve element part 60, and a space between the valve element part 60 and the screw rotor 40 is thereby maintained. <P>COPYRIGHT: (C)2009,JPO&INPIT | ||||||

| <P>PROBLEM TO BE SOLVED: To provide a scroll compressor capable of preventing degrading of compression performance due to leakage caused by torsion assembling errors. <P>SOLUTION: The scroll compressor has a fixed scroll having volute laps with the same tooth thickness Tr formed by an involute curved surface respectively specified with the same base circle radius b on an end plate, and a turning scroll, wherein they are set up to be mutually eccentric at a turning radius ρ only and both scrolls are engaged with each other while respective laps are opposite by shifting both phases at 180° only and the turning scroll compresses the gas by making a revolution turning operation on a circle track as a turning radius ρ while the spontaneous rotation of the turning scroll is prevented by a spontaneous rotation prevention mechanism. The relative relationship of spiral lap involute curves of both scrolls, and dimensions, dimensional tolerances, and assembling criteria of the self-rotation prevention mechanism are fixed so as to make an upright position of the turning scroll and a central value of a permissible self-rotation angle ϕ coincide with each other. <P>COPYRIGHT: (C)2008,JPO&INPIT | ||||||

| PURPOSE: To equalize the contact to a counterpart side end plate of one side lap tip by forming a recessed part with a depth corresponding to this heat expansion on the lap tip part in at least one end central part among fixed and turning scrolls meshed with each other. CONSTITUTION: A pair of scrolls 1, 2 with a lap 4 erected consisting of an involute curve, etc., on an end plate 3 respectively are meshed with each other. Among both scrolls 1, 2, the one is fixed and the other is turned so as not to rotate. In this case, among both scrolls 1, 2, a recessed part 11 with a depth corresponding to this heat expansion is formed on the lap 4 tip part in at least one side central part. A part with 0.5mm or less of a lap 4 height direction size in the tip part of the lap 4 is formed by a material easy to wear, for example ethylene.teflon copolymer, etc. Accordingly, the contact of the lap 4 tip of scroll central part with the opposite side end plate 3 caused by heat expansion is eliminated and any seizure and wear are prevented.
