Patent number: 11767845Abstract: An oil-lubricated rotary vane vacuum pump includes a rotary vane unit, having a rotary vane chamber and a rotary vane rotor, and an oil separator device having an air/oil separating unit that has a filter element with a plug-in ring that can be plug-connected on a housing side. The plug-in ring is designed for radial sealing and axial displaceability in a housing receptacle. The filter element has a moulding for bayonet mounting, which faces the end associated with the outer wall. A mounting wall of the housing, extending at a distance from the outer wall of the housing, is designed to interact with the moulding of the filter element and to form the bayonet mounting. A separate cover closes a mounting opening associated with the filter element in the outer wall of the housing. The cover form-fittingly interacts with the filter element to secure the filter element against rotation.Type: GrantFiled: March 4, 2020Date of Patent: September 26, 2023Assignee: Gebr.

Publication number: 20220362691Abstract: The invention relates to a method for intermittently cleaning a filter in a filter device, which filter device comprises a filter housing and the filter located therein. The filter housing has a medium inlet and a medium outlet for a medium to be filtered. During filter operation, the medium flowing through the medium inlet passes through the filter and exits the filter device via the medium outlet. In order to clean the filter, both the medium inlet and the medium outlet are closed and a negative pressure is produced in the filter housing and a flushing medium is sucked into the filter housing by the negative pressure.Type: ApplicationFiled: November 17, 2020Publication date: November 17, 2022Applicant: Gebr.

Patent number: 6293769Abstract: An electric pump for a liquid has a rotor surrounded by a stator which is disposed in the flow path of the liquid, the rotor being disposed in a rotor compartment, which is sealed from the flow path of the liquid and is predominantly filled with a mixture of air and vaporized liquid. The rotor compartment is in communication with the ambient atmosphere through a vent orifice. A vent system in the form of a labyrinth seal and a liquid-tight, gas-permeable membrane is interposed between the vent orifice and the ambient atmosphere. The rotor bearings are lubricated in one embodiment by leakage liquid and its vaporized product within the rotor compartment. In another embodiment the rotor bearings are disposed in the liquid flow path outside seals between the rotor and the rotor compartment.Type: GrantFiled: February 1, 2000Date of Patent: September 25, 2001Assignee: Pierburg AGInventors: Bernhard Radermacher, Henning Garcke

Patent number: 5765535Abstract: A fuel supply system for an internal combustion engine in which an electrical fuel pump pumps fuel from a fuel tank to a fuel distributor and a pressure switch is connected to respond to the pressure of the fuel. The pressure switch is electrically connected to connect and disconnect electrical power supply to the fuel pump as a function of lower and upper threshold values of pressure of the pumped fuel. The pressure switch contain a storage chamber which stores fuel when the fuel pump is operative andwhen the pump is disconnected, the storage chamber supplies the stored fuel to the full distributor with no back flow to the fuel tank. A pressure reducing regulator is located between the pressure switch and the fuel distributor to reduce the pressure of the fuel supplied to the distributor to a value lower than the pressure of the fuel at the pressure switch.Type: GrantFiled: March 20, 1996Date of Patent: June 16, 1998Assignee: Pierburg AGInventor: Bernhard Radermacher

Patent number: 5472321Abstract: An improvement in a fuel pump for an internal combustion engine in which the fuel pump comprises an electric motor over which fuel is pumped to cool the motor, and a pump mechanism, constituted as a side-channel pump driven by the electric motor, pumps the fuel. The pump mechanism has a pump impeller provided with two opposite radial surfaces each provided with an annular ring of blades respectively cooperating with side channels provided in a pump wall to constitute first and second pump stages. A connecting channel connects an inlet region of the side channel of the second pump stage with a discharge region of the side channel of the first pump stage in an arrangement to substantially eliminate torsional moments acting on the impeller during a fuel pumping operation. A first flat region is formed on the radial surface of the pump impeller in the first pump stage and a second flat region is formed on the radial surface of the pump impeller in the second pump stage.Type: GrantFiled: December 20, 1993Date of Patent: December 5, 1995Assignee: Pierburg GmbHInventor: Bernhard Radermacher

Patent number: 4865522Abstract: A fuel feed device having a first pump assembled with an electric motor in a sheet-metal shell to form a self-contained unit. The drive shaft of the motor projects from the unit and is drivingly connected to an impeller of a second pump whose housing surrounds the impeller. The housing of the second pump surrounds part of the self-contained unit and a sleeve is pushed over the self-contained unit with clearance therebetween and is connected at its lower end to the second pump housing and forms a seal with the self-contained unit by a holding ring and an elastic membrane. The device is easily adapted to casings of the first pump of any form and shape and to requirements, such as changes in filter size, mounting in the fuel tank, and for different types of second pumps.Type: GrantFiled: April 1, 1988Date of Patent: September 12, 1989Assignee: Pierburg GmbHInventor: Bernhard Radermacher

Patent number: 4758141Abstract: A vane pump having a plurality of working chambers each of whose volume changes from a minimum to a maximum value and back again during one revolution, and wherein intake and delivery ports open axially into the working cells and are formed with cross sections adapted for fluid conveyance without internal compression. Such compression is achieved by a valve plate which forms a non-return and is formed with a resilient tongue valve which, commencing from the starting end of the delivery port controls, upon proper pump operation, about two-thirds of the cross section of the mouth of the delivery port.Type: GrantFiled: June 8, 1987Date of Patent: July 19, 1988Assignee: Pierburg GmbHInventor: Bernhard Radermacher
