    摘要： A scroll compressor that suffers no decrease in compression performance due to leakage resulting from a twisting assembly error is provided. This scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll.

    摘要： A scroll compressor comprises a fixed scroll member and a revolving scroll member that engage with each other with their centrifugal walls, wherein the revolving scroll member is supported to revolve with respect to the fixed scroll member, but to avoid self-rotation thereof. The spiral-starting portion of the centrifugal wall comprises non-stepped portions formed along curves of &bgr;1-&bgr;1′ and &bgr;2-&bgr;2′ respectively, and a stepped portion formed along a curve &bgr;1′-&bgr;2′ that provides a thickness increase area encompassed by its upper-side curved surface and its lower-side curved surface. The discharge port is located on the end board of the fixed scroll member to partly overlap with the thickness increase area by partly hollowing the lower side of the stepped portion with the prescribed height.

A tip seal is provided along a join edge which connects top edges on different sides of each step, and a mechanism is provided therebetween to prevent the tip seals from becoming removed from the join edges. Furthermore, in the same scroll compressor, tip seals are provided respectively in two grooves, and join paths are provided respectively between a high-pressure compression chamber, which is formed with the bottom faces as one section, and the two grooves. The pressure inside the high-pressure compression chamber is used as a pressing force for the tip seals.

    摘要： A scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (ρ) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (ρ) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll. The relationship between the involute surfaces of the spiral wraps of the two scrolls and the dimensions, dimensional tolerance, and assembly standards of the rotation-preventing mechanism are determined so that the median value of an allowable angle of rotation (φ) agrees with an upright position of the orbiting scroll.
