    摘要: A variable capacity vane pump is provided, the pump having a pump control ring which is moveable to alter the capacity of the pump and the pump can be operated at either of at least two selected equilibrium pressures. The pump ring is moved by at least first and second control chambers, the control chambers abutting the control ring such that pressurized fluid supplied to them acts on the pump control ring to move the pump control ring to reduce the volumetric capacity of the pump. When pressurized fluid is supplied to only one control chamber, the pump operates at a first equilibrium pressure and when pressurized fluid is also supplied to the second chamber, the pump operates at a second equilibrium pressure. If desired, pressurized fluid can also be supplied only to the second control chamber to operate the pump at a third equilibrium pressure and/or additional control chambers can be provided if required.

    摘要: An eccentric pump with lock valve and with bidirectional rotational operation has an inner slide member (8) which is arranged between the casing (1) and the circular sealing ring (5), the slide member (8) being sealingly but moveably attached to inner surfaces of the casing (1), and the slide member (8) being rotatable between a first position and a second position, and

    the casing (1) has two inlet openings (11,12) and at least one outlet opening (13), and
    the slide member (8) has two through bores (9,10), the first through bore (9) is in communication with one inlet opening (11), the second through bore (10) with at least one outlet opening (13), in the first position of the slide member (8), and the first through bore (9) is in communication with at least one outlet opening (13), the second through bore (10) with the other inlet opening (12), in the second position of the slide member (8), and
    the pin (7) is fixed to the slide member (8) and is sealingly separating the through bores (9,10) from each other.

    Therefore, the eccentric pump can be mounted directly on the force transmitting shaft of the drive and the shaft can rotate on both direction without stopping the liquid discharge

    摘要: The invention relates to a method of operating a variable capacity pump at at least two selectable equilibrium pressures. The pump comprises a first control chamber, a second control chamber, a pump control ring pivotable to alter the capacity of the pump, and a return spring biasing the pump control ring towards a position of maximum volumetric capacity. The method comprises the following steps:
    Supplying pressurized fluid to the first control chamber to create a force on the pump control ring such that the force pivots the pump control ring to reduce the volumetric capacity of the pump, wherein the return spring acts against the pivoting force of the first control chamber to establish an equilibrium pressure; and selectively supplying pressurized fluid to the second control chamber to create a force on the pump control ring such that the force pivots the pump control ring to reduce the volumetric capacity of the pump, wherein the return spring acts against the pivoting force of the first and second control chambers to establish a new, lower, equilibrium pressure.

    摘要: A variable displacement variable pressure vane pump system provides lubrication oil to a mechanical system. The system has a first control mechanism, which can be a control chamber directly acting on the control slider or a control chamber and control cylinder which acts on the control slider and a second control mechanism which is a control chamber and control cylinder which acts on the control slider. A control valve, operated by an engine control unit or other suitable control mechanism, selectively provides pressurized lubrication oil to the second control mechanism to allow the output of the pump system to more closely match the requirements of the mechanical system.
