摘要： PROBLEM TO BE SOLVED: To provide a screw compressor capable of making wear of a gate difficult at a time of stopping the compressor and ensuring high reliability while suppressing manufacturing cost.SOLUTION: A screw compressor comprises: a compression mechanism 20 including a screw rotor 21; an electric motor driving the compression mechanism; a casing in which a low pressure space S1 and a high pressure space S2 are formed; and a regulation mechanism 30. The regulation mechanism 30 includes a slide valve 31 between the casing and the crew rotor. The slid valve 31 has a seal surface 31b slidably contacting a slide contact surface 15a of the casing on an opposite side to the screw rotor 21. The regulation mechanism moves the slide valve in a first interval to controls a capacity of the compression mechanism, and causes the seal surface to slidably contact the slid contact surface to prevent the low pressure space from communication with the high pressure space when the electric motor operates. When the electric motor stops, the regulation mechanism moves the slide valve in a second interval to separate the seal surface from the slide contact surface, and forms a gap between the slide valve and the casing to communicate the low pressure space with the high pressure space.

摘要： PROBLEM TO BE SOLVED: To provide a screw compressor capable of removing foreign matters adhering to an oil filter and suppressing clogging with a relatively simple configuration.SOLUTION: A downstream side of a check valve (31) in a discharge tube (30) is connected to an oil discharge side of an oil filter (25) in an oil supply path (29a) by a bypass pipe (32). An on-off valve (33) is connected to the bypass pipe (32). While a screw rotor (40) operates to rotate, the on-off valve (33) is closed to cut off flow of high pressure refrigerant from the discharge tube (30) to the bypass pipe (32). When the screw rotor (40) stops rotating, the on-off valve (33) opens to allow the flow of the high pressure refrigerant.

摘要： PROBLEM TO BE SOLVED: To provide a screw compressor including a slide valve for regulating the operation capacity and improving the operation efficiency when the operation capacity is set at a small value. SOLUTION: In a casing of the screw compressor, the slide valve (70) is arranged at the side of a screw rotor (40). The casing is formed with a bypass passage (33) for bringing a fluid chamber (23) into communication with a low-pressure space. When the slide valve (70) slides, the size of an opening (34) of the bypass passage (33) in an inner peripheral surface (35) of a cylindrical wall (30) varies and the operation capacity of the screw compressor varies. In the slide valve (70), its end face (P2) is inclined to be along an extending direction of a spiral groove (41) of the screw rotor (40). A seat face (P1) of the cylindrical wall (30) facing the end face (P2) of the slide valve (70) is parallel to the end face (P2) of the slide valve (70). COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a gate rotor capable of improving yield strength to back pressure while holding compression performance. SOLUTION: An elastic modulus of an outside part 30A of a gate rotor body 30 is larger than an elastic modulus of an inside part 30B of the gate rotor body 30. Since the elastic modulus of the inside part 30B is small, the inside part 30B is easily elastically deformed by back pressure, and prevents a deficit of the gate rotor 3 by improving yield strength to the back pressure. While, since the elastic modulus of the outside part 30A is large, the outside part 30A is hardly elastically deformed by the back pressure, and can hold the seal function of a compression space C.

摘要： PROBLEM TO BE SOLVED: To provide a compressor making the best of an economizer effect independently of the rotation speed of a screw rotor. SOLUTION: The higher the rotation speed of a screw rotor 10 becomes, the earlier the timing of an economizer port EP1 to open into a compression chamber 12 is made by a control unit 30. At the high-speed running time of the screw rotor 10, specifically, the economizer port EP1 is opened earlier before the compression chamber 12 is closed. On the other hand, at the low-speed running time of the screw rotor 10, the economizer port EP1 is opened later. COPYRIGHT: (C)2009,JPO&INPIT
