The present invention relates to a centrifugal suction-type hybrid vane fluid machine and, more particularly, to a centrifugal suction-type hybrid vane fluid machine wherein a cam ring, which rotates inside a compressor, has a plurality of final intake openings formed through the same from the inner peripheral edge to the outer peripheral edge thereof, thereby facilitating inflow of a fluid during rotation; an oil passage is formed therein so as to seal inner constituent elements and to apply a backpressure of vanes, thereby preventing leakage of the fluid and reducing friction; the same number of initial fluid discharge openings are formed as that of the vane or fluid chambers, thereby improving the efficiency of the compressor; and the cam ring is installed eccentrically so as to increase the rotational contact force, thereby improving the efficiency of the compressor while having all advantages of conventional compressors.

A vane compressor includes a housing having therein a suction chamber, a discharge chamber having a cover, and a rotor chamber, a rotor having therein a plurality of vane slots, and a plurality of vanes. The housing includes a partition that has a first surface forming the other surface of the rotor chamber and a second surface and separates the rotor chamber from the discharge chamber. An intermediate pressure chamber having a pressure that is lower than the discharge chamber and higher than the suction chamber is formed between the partition and the cover. A part of the second surface and a part of a covering surface of the discharge chamber cover are spaced away from each other by the intermediate pressure chamber. The intermediate pressure chamber is disposed so as to overlap at least a part of the other surface of the rotor chamber.

A vane pump includes a pump cartridge that is accommodated in an accommodating space defined by the concave portion and the pump cover. The pump cartridge includes a first side plate that is provided between the bottom portion of the concave portion in the pump body and a cam ring; first pins that are provided so as to extend from the cam ring to the first side plate; and second pins that are provided so as to extend from the first side plate to the pump body.

A noise-reduction mechanism is coupled to a portion of an oil-pump system and includes various tunable components that are configurable to affect specific frequency ranges of noise within the system. The mechanism includes a series of channels that are coupled to a portion of the oil-pump system (e.g., outlet tube) and are coupled to a reservoir.
