  • Patent number: 11261865
    Abstract: A screw compressor includes screw and gate rotors, a cylindrical wall, and a slide valve including a valve body and a guide portion. The valve body extends in an axial direction of the cylindrical wall and has a crescent shape in a cross section in a perpendicular direction to the axial direction. A radius of curvature of an inner arc shaped curved surface of the crescent shape is substantially equal to a radius of curvature of an inner peripheral surface of the cylindrical wall. A radius of curvature of an outer arc shaped curved surface of the crescent shape is smaller than the radius of curvature of the inner arc shaped curved surface, and a central angle of the outer arc shaped curved surface is 180° or less. The guide portion allows movement of the valve body in the axial direction and restricts movement in the perpendicular direction.

  • Patent number: 11136982
    Abstract: A screw compressor includes a casing, a screw rotor, a discharge passage, and at least one muffler space. The casing includes a cylindrically-shaped cylinder, a main body surrounding a vicinity of the cylinder, and a high-pressure fluid passage provided between the main body and the cylinder. The screw rotor includes a plurality of helical grooves. The screw rotor is inserted into the cylinder to define fluid chambers. A fluid is sucked into the fluid chambers to compress the fluid. The discharge passage is disposed in the casing. The discharge passage guides the fluid that has been discharged from the fluid chambers to the high-pressure fluid passage. The at least one muffler space is disposed in the casing. The at least one muffler space communicates with the discharge passage so as to reduce a pressure fluctuation of the fluid flowing from the discharge passage to the high-pressure fluid passage.

  • Patent number: 9200632
    Abstract: A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. 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.
