摘要： PROBLEM TO BE SOLVED: To improve the efficiency of a compressor in a single screw compressor by suppressing wear of a gate. SOLUTION: In the single screw compressor, gates (51) of gate rotors (50) are engaged with helical grooves (41) of a screw rotor (40). In each helical groove (41) of the screw rotor (40), the region from the start point of the groove (41) to the middle of a compression stroke is a suction side portion (45) and the remaining region (region to the end point) is a discharge side portion (46). In the suction side portion (45), the clearance between each gate (51) and wall surfaces (42, 43, 44) of the suction side portion (45) is substantially zero. The clearance between each gate (51) and wall surfaces (42, 43, 44) of the discharge-side portion (46) is greater than the clearance between the gate (51) and the wall surfaces (42, 43, 44) of the suction side portion (45) and gradually expands toward the end points of the helical grooves (41).

摘要： PROBLEM TO BE SOLVED: To reduce energy required for operation while sufficiently securing a discharge quantity of fluid from a single-screw compressor. SOLUTION: In this single-screw compressor, a gate (51) of a gate rotor (50) is engaged with a helical groove (41) of a screw rotor (40). In each helical groove (41) of the screw rotor (40), a region from its starting end up to the middle of a compression stroke functions as a suction side (45), and the remaining portion (a portion up to the tail end) functions as a discharge side 46. At the discharge side 46, a clearance between a gate (51) and its wall surfaces (42, 43 and 44) is substantially zero. The clearance between the gate (51) and the wall surfaces (42, 43 and 44) is greater than the clearance between the gate (51) and the wall surfaces (42, 43 and 44) of the discharge side (46), and gradually becomes smaller from the starting end to the tail end of the helical groove (41).

摘要： PROBLEM TO BE SOLVED: To realize high efficiency of a swing compressor, by bringing a discharge port close to a compression completing position of a piston as much as possible so as to be openable, and delaying a discharge starting angle of a discharge valve to reduce invalid power of the piston.
SOLUTION: A piston 9 is revolved in a cylinder chamber 6a through blades 31 with an oscillating bush 32 as a supporting point, as a drive shaft is driven. Each discharge port 22 is provided so that its semi-circular part is overlapped on an outer circumferential part of the oscillating bush on the high pressure chamber 35 side of the blade and a peripheral part of a cylinder 6 opposite to the outer circumferential part, when seen from an axial direction of a cylinder. In an overlapped part with the discharge port at upper and lower positions of the outer circumferential part of the oscillating bush and an overlapped part with the discharge port at upper and lower positions of a cylinder supporting part, a pair of upper and lower notched parts 41 notched in a semi-conical shape is formed in the upper and lower positions of an outer circumferential part of the oscillating bush and in the upper and lower positions of a cylinder supporting part across the overlapped parts so that the high pressure chamber communicates with the discharge port at the compression completing position of the piston.

摘要： PROBLEM TO BE SOLVED: To improve efficiency in a single-screw compressor by reducing motive power consumed by the slide of a screw rotor and a gate rotor. SOLUTION: In the screw rotor (40), a first suction-side region (45) is firmed on the first sidewall face (42) of a helical groove (41). On this first sidewall face (42), a portion from its starting end up to a position at which a compression chamber (23) is closed off forms the first suction side region (45) as a whole. The first suction side region (45) is made lower than the portion of the first suction side region (45) in the first sidewall face (42), so that it does not contact with a gate (51) of the gate rotor (50).
