摘要： A lubricant vane pump for providing a pressurized lubricant for an internal combustion engine includes a pump housing enclosing a pumping cavity comprising a charge zone and a discharge zone. A shiftable control ring envelops the pumping cavity. A pump rotor comprising vanes divides the pumping cavity into pumping chambers. The pump rotor is radially slidable and rotates in the control ring from the charge zone to the discharge zone. A spring chamber comprises a pretensioning element which pushes the control ring to a high pumping volume direction. A control chamber is configured so that a lubricant pressure in the control chamber moves the control ring to a low pumping volume direction against a force of the pretensioning element. A pumping cavity outlet port is connected to the control chamber. A pressure equilibration channel drains the lubricant from the pumping chamber in the discharge zone into the spring chamber.

One of the net-displacement control methods (47) includes obtaining a desired input parameter (23) and a relative position (21) of a first member (43) and a second member (35) of a fluid displacement mechanism. A determination of a first and second output value is then made for each of a plurality of volume chambers (45) when the volume chambers (45) are supplied with fluid at fluid inlet and fluid outlet conditions, respectively. A total output value is then computed for each of a plurality of control valve configurations (63) and compared to the desired input parameter (23). The control valve configuration (63) with the total output value most similar to the desired input parameter (23) is then selected. A plurality of control valves (15) are then actuated in accordance with the selected control valve configuration (63).

摘要： Delivery units are already known which have a drive rotor and an output rotor driven by the drive rotor, which are supported in a housing, interact in a meshing manner through a spur toothing in each case and draw fluid through at least one inlet and push said fluid out through an outlet, wherein the inlet and the outlet are separated from each other by two separating webs. In order to control the flow rate through the delivery unit, a rotational speed control, a bypass control, or, for gases, a suction throttling, for example, can be carried out. A rotational speed control is energy efficient, but very expensive, because an electric motor must be used, the rotational speed of which can be controlled. In the bypass control, the fluid is delivered from the outlet through a bypass back to the inlet, which however is energetically unfavorable and connected to hydraulic losses. The delivery unit according to the invention is improved in such a way that on the inlet side the flow rate can be controlled very easily and with few hydraulic losses and on the outlet side the inner compression can be adjusted in the event of delivery of gases. According to the invention, at least one of the separating webs (9,10) has at least one control opening (12), the opening cross-section of which can be controlled with a control slide (13).

摘要： A pump including a pressure plate having two inlets and outlets, wherein each inlet has an auxiliary intake port in fluid communication with the inlet, and each outlet has an auxiliary discharge port in fluid communication with the outlet, and a cam/rotor assembly attached to the pressure plate. The cam/rotor assembly includes a rotatable cam having an opening, a rotor within the cam opening, the rotor having multiple radial slots, and multiple vanes that move within the slots, wherein a pumping chamber is defined by a space between rotor and cam. Rotor rotation within the cam causes the vanes to extend and retract within the pumping chamber. The movement of the vanes discharges into the outlets and auxiliary discharge ports a fluid drawn into the pumping chamber via inlets and auxiliary intake ports. The auxiliary inlet and auxiliary discharge ports reduce pressure pulsations in a variable displacement dual-lobe vane pump.

摘要： A vane-type motor is disclosed including a rotor disposed in a housing having a plurality of cam rings surrounding the rotor, which cam rings are displaceable relative to one another in the circumferential direction. Vanes associated with the cam rings subdivide a work chamber provided between the rotor and the cam rings into work cells and side plates laterally confine the work chamber. An inlet channel supplies pressure fluid to the work chamber and a discharge channel provides for discharge of the pressure fluid from the work chamber. Control channels are provided to preclude pressure impacts and noises with the cam ring displaced. The control channels terminate in the work chamber and connect the work chamber to the inlet channel. The rotor forms a control element for the control channels.

摘要： A positive displacement hydraulic pump (motor) which employs a gerotor gear set for displacing (for being displaced by) the fluid. The gear set includes an externally toothed rotor and an internally toothed stator ring. The teeth of the stator ring comprise roller vanes for meshing with the teeth of the stator. The capacity of the pump can be varied, in one embodiment by varying the degree of overlapping of the teeth of the rotor and stator ring and thus varying the effective displacement of the gears, and in another embodiment by employing a second gerotor gear set, the phase of which can be adjusted with respect to the first gerotor gear set for varying the effective displacement of both sets.
