The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.

摘要： The present invention provides a screw compressor wherein, even if a gate rotor flexes owing to a temperature differential between a casing and a screw rotor during operation of a compressor, the gate rotor is prevented, with a simple configuration, from biting into the screw rotor, which reduces the amount of wear of the gate rotor and prevents a decline in the compressor's performance. The gate rotor (3) comprises a gate rotor main body (30) and a shaft (40) to which the gate rotor main body (30) is attached. An elastic body (5) is disposed between (S) the axle (41) of the shaft (40) and the hole (32) of the gate rotor main body (30).

The gate rotor includes a plurality of flat-plate-shaped gates formed in a radial pattern and meshing with a helical groove of the screw rotor. Fluid in a compression chamber defined by the screw rotor, the casing and the gates is compressed when the screw rotor is rotated. The gate rotor supporting member includes a gate supporting portion supporting each gate from a back surface side. The gate rotor and the gate rotor supporting member form a gate rotor assembly including a pressure introduction channel configured and arranged to introduce a fluid pressure on a front surface side of each gate into a gap between a back surface of the gate and the gate supporting portion.

摘要： A screw compressor includes a casing, a screw rotor disposed in a cylinder portion of the casing to define a compression chamber, and a capacity control slide valve. Fluid sucked into the compression chamber is compressed by rotation of the screw rotor. The slide valve is slidable along a rotation axis of the screw rotor and is opposed to an outer circumferential surface of the screw rotor. The slide valve includes a dynamic pressure generator formed on an opposed surface of the slide valve that is opposed to the screw rotor to generate a dynamic pressure using fluid in contact with the opposed surface of the slide valve. The slide valve is configured so that the dynamic pressure generated by the dynamic pressure generator avoids contact between the slide valve and the screw rotor.
