    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: A sliding-vane rotary compressor includes a cylinder having a plurality of discharge holes aligned in an axial direction of the cylinder, and a corresponding number of discharge valves normally closing the respective discharge holes. Respective openings of the discharge valves are limited in such a manner as to increase progressively in a direction from a front side to a rear side of the cylinder to thereby produce a pressure difference between the front and rear sides of the cylinder. With this pressure difference, the cylinder is normally urged toward one side and hence is unlikely to oscillate in the axial direction. The compressor thus constructed is capable of operating silently without generating an unpleasant oscillating noise.

    摘要: A variable capacity compressor has first and second discharge pressure chambers provided, respectively, on opposite sides of a cylinder. A first communication passage communicates the first and second discharge pressure chambers with each other. A discharge port directly communicates with the first discharge pressure chamber. A capacity control device is operable in response to control pressure for controlling the capacity of the compressor and has a control pressure chamber in which the control pressure prevails. A second communication passage communicates the second discharge pressure chamber with the control pressure chamber. The second discharge pressure chamber is formed of an oil sump section communicating with the first discharge pressure chamber through the first communication passage, and a high pressure-introducing section supplied with compression medium delivered from the cylinder, wherein partition walls are provided which isolate the high pressure-introducing section from the oil sump section.
