摘要：【課題】省エネルギと騒音低減のどちらを優先したい場合にも対応可能とし、スクリュー圧縮機の使い勝手を向上させる。【解決手段】スクリュー圧縮機では、スクリューロータが回転すると、低圧空間内の冷媒が圧縮室へ吸入されて圧縮され、その後に高圧空間へ吐出される。スクリュー圧縮機は、その内部容積比が可変である。コントローラは、スクリュー圧縮機の消費電力が少なくなるように内部容積比Viを調節する省エネ制御モードと、スクリュー圧縮機の騒音が小さくなるように内部容積比Viを調節する低騒音制御モードとを選択可能である。【選択図】図7

摘要： 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. 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). COPYRIGHT: (C)2009,JPO&INPIT

摘要： 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. 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.
