摘要： In a rotary compressor of a vane rotary type, an outer peripheral surface of an eccentric portion of a shaft on a side adjacent to a center of the shaft is located radially inwardly of an outer peripheral surface of a main shaft inserted in a main bearing and that of an auxiliary shaft inserted in an auxiliary bearing. Also, a back clearance means used in mounting a piston on the shaft is provided in each of an inner peripheral surface of the piston and the eccentric portion of the shaft. Such configurations can reduce a diameter of the eccentric portion. A reduction in diameter of the eccentric portion can reduce a viscous force of oil acting between the eccentric portion of the shaft and the inner peripheral surface of the piston to thereby reduce a rotational moment about a center of the eccentric portion of the shaft, which rotational moment acts on the piston in a direction of rotation of the shaft, thus making it possible to reduce a sliding loss that is generated by a reciprocating motion of a vane in a vane groove.

摘要： A hermetic compressor includes a plurality of compressing mechanisms. Each of the compressing mechanism includes a rotary cylinder having a groove, and a piston slidable in the groove, so that a compressing stroke is carried out by rotation of said piston on a locus of a radius E about a point spaced apart at a distance E from the center of said rotary cylinder. A partition plate is interposed between the rotary cylinders of the adjacent compressing mechanisms. The partition plate is provided with a communication bore through which a shaft is passed. The partition plate is provided with cranks on which said pistons can be mounted. A motor mechanism section is adapted to drive the pistons of the compressing mechanisms by the common shaft. At least one of the compressing mechanisms is different in phase in a compressing stroke from the other compressing mechanisms. The rotary cylinders of the adjacent compressing mechanisms and said partition plate sandwiched between such rotary cylinders are formed from different members, and relatively non-rotatably connected to each other. Thus, the piston rotated in the above manner about the above-described point is not necessarily requited to be rotated about its axis during the rotating movement about such point, and need be only slid along the groove. Therefore, the piston can be formed into a non-circular shape, whereby the area of contact of the piston with the groove can be increased to enhance the sealability, thereby enhancing the suction and compression efficiency.

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.

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.

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.
