| 20120039736 | PNEUMATIC MOTOR UNIT WITH INTEGRATED VOLTAGE GENERATING MEANS - A pneumatic motor unit includes a housing with an air inlet passage, an exhaust air outlet passage, and a rotation motor which generates a pulsating exhaust air outlet flow. The motor unit further includes a voltage depending device which communicates signals in response to at least one of an actual motor condition and operation parameter values, and a voltage generating section which is connected to the voltage depending device and which includes a piezoelectric element provided in the exhaust air outlet passage and arranged to be activated by pressure pulses of the pulsating exhaust air outlet flow from the motor. The piezoelectric element is tongue shaped and rigidly secured at one end, and is arranged to be swung in a two-way movement relative to a central rest position to thereby generate an alternating current voltage. | 02-16-2012 |
| 20120164016 | Rinsing Arrangement for Tribological Contact Area and Rotary Vane Pump with such an Arrangement - A cooling and lubricating arrangement of tribological contact areas is disclosed. The arrangement includes tribological contact areas that slide over one another, of which at least one contact area has a surface contour with surface depressions in which a lubricant is stored. The surface contour forms a number of elongate grooves, the gap heights of which, at least in respect of respectively two adjacent grooves, are preferably different. | 06-28-2012 |
| 20120183426 | VARIABLE-DISPLACEMENT LUBRICANT PUMP - A variable-displacement lubricant pump for providing a pressurized lubricant includes a rotor with at least one radially slidable vane configured to rotate in a shiftable stator ring. A first plunger is configured to push the shiftable stator ring into a high pumping volume direction. A pressure control system is configured to control a lubricant discharge pressure of the pressurized lubricant. The pressure control system comprises a first control chamber with the first plunger being configured to move in an axial direction and a side wall. A pump outlet port is connected to the first control chamber via a first pressure conduit. A movable outlet opening is disposed in the side wall of the first control chamber, is connected to a low pressure, and is configured to move with an axial projection and to be actuated by a thermostatic element. The first plunger can cover and close the movable outlet opening. | 07-19-2012 |
| 20120308424 | SEALING DEVICE, AND PUMP DEVICE USING SAME - A sealing device is constructed by a seal ring and a back ring, the back ring is constructed by a lip packing provided with an inner lip and an outer lip in one end portion in an axial direction of an annular base portion, and is provided with an annular protrusion for setting a diametrical direction compression margin in the back ring in an outer peripheral surface of the annular base portion. The outer lip has a function of sealing the sealed fluid by coming into close contact with the cylinder and releasing the accumulated pressure by being pushed by a pressure at a time of a pressure accumulating phenomenon in the another space in the axial direction so as to be spaced from the cylinder. The annular protrusion is provided with a flow path for introducing the accumulated pressure to the outer lip. | 12-06-2012 |
| 20130034463 | Gear Pump - A gear pump includes a plurality of gear wheels rotatably retained in a pump housing and that engage in one another for the conveyance of a medium. One of the gear wheels is driven by a pump shaft, which can be coupled to a drive by means of a coupling end. To maintain a uniform conveyance flow, in particular with strongly fluctuating operational pressures, during alternating load states, within a single rotation, a brake ring is disposed on the circumference of the pump shaft, which acts with at least one brake surface on a friction surface of the pump shaft or on a friction surface of the pump housing. | 02-07-2013 |
| 20130045126 | TAPERED SOUND OUTLET VANE PUMP - The invention relates to a vane cell pump comprising an electrical pump unit that has a pump chamber into and out of which a fluid can flow and also a rotor with a number of vanes to compress the fluid before flowing out from the pump chamber. The vane cell pump also comprises a sound-damping mechanism into which the fluid can flow after flowing through the pump chamber and that has a sound-damping cover attached to a part of the pump chamber and defining a sound-damping volume. A preliminary sound-damping mechanism with at least one preliminary sound-damping outlet from which the fluid can flow may be arranged within the sound-damping volume, wherein the preliminary sound-damping outlet has a cross-sectional profile tapering in the direction of fluid outflow. | 02-21-2013 |
| 20130108500 | REBUILDABLE CASSETTE ASSEMBLY FOR DISPLACEMENT PUMP | 05-02-2013 |
| 20130121867 | ROTARY PUMP WITH IMPROVED SEAL - A rotary pump with an improved seal on a control pressure chamber, including: a housing having a delivery chamber; a feed wheel rotatable in the delivery chamber; an actuating member surrounding the feed wheel forming delivery cells and moveable in the housing relative to the feed wheel. The control pressure chamber is delineated by the actuating member together with axially facing axial co-operating surfaces, forming an axial sealing gap and a radial sealing gap. A control fluid can be introduced into the control pressure chamber for applying pressure to the actuating member to exert an actuating force in the actuating direction; a restoring device for generating a restoring force; and a sealing element arranged on the actuating member or the circumferential co-operating surface. To compensate for a change in gap width of one of the axial sealing gaps, a base leakage cross-section is provided on the sealing element. | 05-16-2013 |
| 20130136644 | OIL PUMP FOR VEHICLE - An oil pump for a vehicle including a sealing apparatus is provided for preventing leakage of oil from the regulator chamber. The oil pump includes a sealing chamber formed between the outer ring and the housing, a sealing apparatus disposed in the sealing chamber, and an oil passage formed in the outer ring to facilitate a fluid communication of the sealing chamber with the regulator chamber. The sealing apparatus includes a contact portion, first and second sealing members. The first sealing member closely contacts the contact portion if the second sealing member is pushed by the hydraulic pressure of the regulator chamber supplied thereto through the oil passage, and thus prevents leakage of oil from the regulator chamber. | 05-30-2013 |
