摘要： A vane compressor has a vane back pressure adjustment device including back-pressure chambers defined in a vane-supporting rotor and surrounded by vanes and side blocks secured to axial ends of a cylinder. The back-pressure chamber has axial ends disposed to follow a path against each of the side blocks when the rotor rotates. The path is divided into at least one high-pressure zone in which the vanes move across a pump outlet defined in the cylinder, and at least one normal-pressure zone which is the remainder of the path. In the normal-pressure zone, oil grooves defined in surfaces of the side blocks which face the rotor and supplied with oil from an oil sump in the vane compressor are in communication with the back-pressure chambers, to thereby maintain the oil pressure in the back-pressure chambers at a pressure level in the oil sump. In the high-pressure zone, the back-pressure chambers are out of communication with the oil grooves so that the oil fed into the back-pressure chambers is confined therein, except through a restrictor means. When the vanes move across the pump outlet, the vanes enter the high-pressure zone to trap oil in the back-pressure chambers to thereby elevate the oil pressure in the back-pressure chambers to a high level. Therefore, the vanes are prevented from being retracted deeply into vane slits in the rotor and then popping out into hitting engagement with the cylinder.

摘要： The endless camming peripheral surface of the pump housing, which performs one cycle of suction, compression and discharge of fluid in cooperation with the vanes and the rotor, comprises an increasing radius portion along which the amount of protrusion of each vane gradually increases with movement of the vane, and first and second decreasing radius portions along which the amount of protrusion gradually decreases with movement of the vane, the three portions being successively arranged in the order mentioned in the advancing direction of the vanes. Each of the three portions has such a cam profile that the velocity of radial movement of each vane varies at a rate gradually decreasing as the vane approaches the terminating end of the portion. Preferably, the above one-cycle performing portion further includes one or two constant radius portions located between the above three portions, along which the amount of protrusion of each vane is kept substantially constant with movement of the vane.

摘要： An improved rotor is disclosed, for use with movable vanes in pumps, compressors and the like. The rotor is equipped with slots in which the vanes are located. Each slot has a leading surface and a trailing surface. Two embodiments of this invention are taught. In one embodiment, a groove is cut into the trailing surface of each slot, so that a specially designed rod-like bearing may be interposed between the rotor and the vane to reduce friction between the trailing face of the vane and the trailing surface of the rotor. In the other embodiment, an additional groove is cut in the leading face of the vane so that a similar bearing may be interposed between the leading face of the vane and the leading surface of the slot. As a result of these designs, friction between the vane and the rotor is much reduced, and a substantially longer work-life results.

摘要： A cylindrical yoke 8 bonded to an inner surface 44 of a cylindrical portion 43 of a rotor case 40 of a motor has a yoke separating slit 85 for separating the yoke 8 in the circumferential direction. A cylindrical rotor magnet 9 is partially bonded to an inner surface 81 of the yoke 8 at a plurality of bonded portions 10 formed apart from one another for the same intervals in the circumferential direction. When the cylindrical portion 43 has been expanded by heat, the yoke separating slit 85 is expanded and the yoke 8 follows the non-bonded portion of the cylindrical portion 43. Therefore, distortion of the cylindrical portion 43 can be prevented. In the non-bonded portions 11 between the yoke 8 and the rotor magnet 9, deformation occurs such that an inner surface 81 of the yoke 8 is separated from an outer surface 92 of the rotor magnet 9. Thus, damage of the rotor magnet 9 can be prevented.
