    摘要： A back pressure chamber 12 provided on a back surface of an orbiting scroll 5 is divided into an inner region 12a and an outer region 12b by an annular seal 11. A diameter d of the annular seal 11 is set 0.5 times or more of a diameter D of an orbiting mirror plate 5a. With this, plus thrust force can be applied to the orbiting scroll 5 irrespective of magnitude of a discharge pressure Pd applied to the inner region 12a. Therefore, it is possible to push the orbiting scroll 5 against the fixed scroll 4 only by back pressure of discharge pressure. A set pressure Pm of the outer region 12b is reduced to a value close to a suction pressure Ps, a pressure adjusting mechanism 20 is swiftly opened after a scroll compressor is started. With this, lubricant oil is supplied from the outer region 12b to the suction space 9 without a time lag.

    摘要： A scroll compressor, whose back pressure is easily controlled and compression efficiency is high, is provided. The scroll compressor includes a plurality of compression chambers formed by engaging a fixed-scroll wrap and an orbiting-scroll wrap, and a back pressure chamber formed at an opposite side of the orbiting-scroll wrap of a orbiting-scroll. The scroll compressor additionally includes a high pressure chamber and a middle pressure chamber, which are formed by dividing the back pressure chamber using a seal. Moreover, the scroll compressor includes a first path for supplying lube oil from the high pressure chamber to the middle pressure chamber, and a second path for supplying the lube oil from the middle pressure chamber to an suction chamber of the compression chambers. The first path is intermittently opened by orbit of the orbiting-scroll.

    摘要： A back pressure chamber (12) provided on a back surface of an orbiting scroll (5) is divided into an inner region (12a) and an outer region (12b) by an annular seal (11). A diameter d of the annular seal (11) is set 0.5 times or more of a diameter D of an orbiting mirror plate (5a). With this, plus thrust force can be applied to the orbiting scroll (5) irrespective of magnitude of a discharge pressure Pd applied to the inner region (12a). Therefore, it is possible to push the orbiting scroll (5) against the fixed scroll (4) only by back pressure of discharge pressure. A set pressure Pm of the outer region (12b) is reduced to a value close to a suction pressure Ps, a pressure adjusting mechanism (20) is swiftly opened after a scroll compressor is started. With this, lubricant oil is supplied from the outer region (12b) to the suction space (9) without a time lag.

    摘要： a First gap 15 in a thrust direction between teeth bottoms of a fixed mirror plate 2b and teeth tips of an orbiting lap 4a, and a second gap 16 in the thrust direction between teeth bottoms of an orbiting mirror plate 4b and teeth tips of a fixed lap 2a are formed such as to gradually increase from an outer peripheral side to an inner peripheral side of a scroll compressor, the first gap 15 is made greater than the second gap 16. Contact surface pressures of the laps 2a and 4a are kept low with respect to pressure deformation, contact pressure of the teeth tips of the fixed scroll part 2 and the teeth bottoms of the orbiting scroll part 4 are equally maintained. With this loads applied to the scroll parts 2 and 4 are equally received by a thrust surface.

    摘要： A hermetic compressor includes a compressor mechanism section 40 which includes first and second rotary cylinders 41a and 41b, and first and second pistons 42a and 42b eccentrically rotated in first and second grooves 42a and 43b in the first and second rotary cylinders 41a and 41b, upper and lower bearings 50a and 50b which clamp the first and second rotary cylinders 41a and 41b, and a casing 51. A projection, 64, a projection 66 or a recess 67 is formed on slide faces in the components of the compressor mechanism section 40, whereby the power loss due to the viscosity is reduced remarkably by reducing the sliding area of the slide faces. Thus, the efficiency of the compressor can be enhanced, and the inclination and the eccentricity of the rotary cylinder can be suppressed to the minimum.
