摘要： A screw compressor according to some embodiments includes a screw rotor, a rotor casing accommodating the screw rotor, and an internal-volume-ratio-adjusting valve capable of changing internal volume ratio. The internal-volume-ratio-adjusting valve includes a valve body movable along an axial direction of the screw rotor and defining a gas-discharge position, and a cylinder containing at least one pressurizing chamber with a cylinder rod and a piston. The cylinder rod is coupled to the valve body and disposed along the axial direction. The piston is fixed inside the pressurizing chamber to the cylinder rod and divides the pressurizing chamber into two pressurizing spaces along the axial direction. The screw compressor further includes a first communication passage connecting one of the two pressurizing spaces with the discharge gas passage, and a second communication passage connecting the other with a just-before-discharge tooth space immediately before a tooth space that communicates with the discharge port.

摘要： A liquid injection type screw compressor in which, in a compression stroke of an working space formed by male and female rotors, liquids such as oil or water is prevented from leaking from the high pressure working space to a gas inlet side, suction resistance of gas sucked from the gas inlet to a rotor casing is reduced to improve volumetric efficiency, and shape forming of the casing is simplified.
The liquid injection screw compressor has the male and female rotor pair of screw rotors, the rotor casing (1a, 1b) having a bore for receiving the rotors, a gas suction opening and a gas outlet that are provided in both end sections of the casing and communicate with the bore, and a lip section (4) projected from a bore surface (2) positioned more on the upstream side than a suction seal line (5) of the casing in order to prevent a back flow of the liquid from the bore surface toward the gas inlet side. The lip section (4) is positioned in a region surrounded by the suction seal line (5) and a line separated by a distance of one screw pitch of the rotors from the suction closure line (5) to the suction opening side.

摘要： In a housing 20 of an oil-cooled screw compressor 10, a separation gas supply path 59 through which separation gas is supplied to a separation gas supply gap 58 defined between a first seal unit and a second seal unit of a seal device 50, and a pressure balancing path 60 through which an area closer to a screw chamber 20a than the first seal unit in a discharge side seal chamber 20d communicates with a compression chamber at a pressure higher than an intake pressure and lower than a discharge pressure, are defined. A check valve 62 that restricts a flow of a fluid in a direction from the screw chamber 20a to the discharge side seal chamber 20d is disposed in the pressure balancing path 60.
