PROBLEM TO BE SOLVED: To suppress breakage of a gate engaged with a spiral groove of a screw rotor without increasing the thickness of a gate rotor, in a single screw compressor.SOLUTION: In a single screw compressor, a plurality of gates 51 are formed by resin plate members 53 respectively comprising a resin tubular body. On one of contact surfaces 53a, 57a between each resin plate member 53 and a gate support part 57 supporting the gate 51 formed by the resin plate member 53, a projection 63 is formed, and on the other surface, formed is a hole 61 housing the projection 63 in an immovable manner in the thickness direction of the resin plate member 53.SELECTED DRAWING: Figure 6 |
