摘要： A scroll compressor for reducing fluid leakage at step portions (42, 43) scroll members and improving the compression efficiency is disclosed. The reduction of leakage and a high compression efficiency can be realized without increasing the precision in the manufacture of the members. Between the engaged scroll members, a high-pressure space (C1) is formed close to the spiral center, and among points (P1, P2, P3) at which the spiral walls (12b, 13b) contact with each other immediately before the innermost closed space (C2, C3) communicates with the high-pressure space (C1), the innermost point (P1) is defined as a base point. The angular distance from the base point (P1) to the outer end (13i) of the spiral, measured along the inner-peripheral face of the spiral wall (13b), is approximately 4π rad. The angular distance from the base point (P1) to the step portion (42, 43) of each end plate (12a, 13a), measured along the inner-peripheral face of the spiral wall (12b, 13b), is equal to or more than approximately 3π rad.

摘要： A screw fluid machine is disclosed particularly for use as a vacuum pump. The machine consists of a male rotor (301) having teeth mated with a female rotor (302) and mounted for rotation in a casing (109) to form fluid chambers. Discharge ports (304,305) are formed in a screw end face plate (303a,303b) constituting a part of the casing (109) so that an end face of the teeth of each rotor (301,302) opens and closes each discharge port (304,305). A set of discharge ports (304) are provided on the male rotor side whose number is smaller than the total number of teeth of said male rotor (301) and a set of discharge ports (305) are provided on the female rotor side whose number is smaller than the total number of teeth of said female rotor (302). Each of the discharge ports (304,305) are provided with a pressure adjustment device (307) which opens when the pressure in said chambers exceeds atmospheric pressure.

摘要： In a screw fluid machine including male and female rotors which are engaged with each other, a casing for accommodating both the male and female rotors, fluid working rooms which are formed by the male and female rotors and the casing, and fluid inlet and outlet ports which are provided in the casing so as to intercommunicate with one end portion and the other end portion of the working rooms, the helix angle of the screw gear constituting each of the male and female rotors is set to be continuously varied in a helix advance direction. Further, the screw gear is designed so that the peripheral length of a pitch cylinder in a helix advance direction on a development of a tooth-trace rolling curve on the pitch cylinder of the screw gear can be expressed by a substantially monotonically increasing function.
