    Abstract: A vane pump includes: a housing with a first end-facing wall and a second end-facing wall which delineate a delivery chamber on one end-facing side each, and with a circumferential wall which extends around the delivery chamber; a rotor which can be rotated about a rotational axis in the delivery chamber and which forms a first axial gap with the first end-facing wall and a second axial gap with the second end-facing wall; multiple vanes which can be moved back and forth in guide slots of the rotor, wherein the guide slots have sub-vane regions which are connected to the high-pressure side of the delivery chamber in order to apply pressure to the underside of the respective vanes; and a collecting structure for collecting fluid via the first axial gap.

    Abstract: 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.

    Abstract: A rotary pump-flowmeter comprises a body including a cylindrical cavity and a rotor assembly including at least one flange disposed within the cylindrical cavity in a rotatable arrangement about an axis of rotation parallel to and offset from the central axis of the cylindrical cavity and a plurality of flaps having a round first edge and a crescent second edge disposed about the axis of rotation and supported by the flange, wherein each of the plurality of flaps is pivotable about an axis of pivot parallel to and offset from the axis of the rotation and coinciding with the center of the radius defining the round first edge of the flap. Each individual flap includes at least one cam roller anchored to one end face of the flap in a rotatable arrangement about an axis parallel to and offset from the axis of the pivot of the flap. A cam guide groove included in a rotary member rotatable about an axis parallel to and offset from the axis of rotation of the rotor assembly guides the orbiting motions of the cam rollers about the axis of rotation in such a way that a clearance of small tolerance is maintained between the extremities of the crescent edges of the flaps and the inner cylindrical surface of the cylindrical cavity, wherein the rotary member is rotated by the rotating motion of the rotor assembly positively or frictionally.

    Abstract: 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.

    Abstract: The invention relates to a vane pump comprising a rotor which is arranged therein, rotatably driven by a drive shaft. The rotor is provided with several grooves which are distributed through the circumference thereof and which extend substantially radially with respect to the axis of rotation of the rotor. In each groove a blade-shaped conveying element is slidingly guided. The end walls of the pump housing are adjacent to the rotor in the direction of the axis of rotation thereof. At least one ring-shaped groove surrounding the axis of rotation of the rotor is embodied in at least one front side of the rotor. The ring-shaped groove is connected to lower areas restricted by the blades in the grooves of the rotor, and to pressure areas. In a preferred embodiment, the ring-shaped groove is formed in the rotor by shaping.

    Abstract: A rotary-vane pump includes a pressure chamber in which a constant pressure is developed, and a pair of discharge passages connecting the pressure chamber to a discharge port. On of the discharge passages is provided with only an orifice so as to supply a constant flow rate of fluid to the discharge port. The other of the discharge passages is provided with an orifice and a flow control valve. The flow control valve controls opening and closing of the other discharge passage in such a manner that the rate of flow through the other discharge passage decreases with increasing rotational speed of the pump. The flow control valve includes a spool having a pair of axially spaced first and second lands, an annular relieved section between the first and second lands, and a guide post. The annular relieved section forms an annular chamber constituting part of the other discharge passage. A spring for urging the spool in the direction to close the other discharge passage, has one axial end retained by the second land and the guide post. The spring is disposed in a spring chamber which is fluidly separated from the annular chamber by the second land. The spring chamber is in fluid communication with the discharge port.
