Patent number: 11339781Abstract: A screw-spindle pump stage having a drive spindle and a running spindle which runs opposite the drive spindle and a pump housing for receiving the two screw spindles. The pump housing 16 has an offset interface with centering action, for a statically determined coupling to an electric motor. The pump housing has an offset section functioning as an abutment, which is able to be abutted against the electric motor for the application of an axial preload. At least one pressure region of the abutment section, which is close to the interface and, during a rolling, is encapsulated, and at the same time sealingly enclosed, by a sheet-metal casing, forms a rolling region of the pump, the screw spindles, together with the associated pump housing section, at least partially project from the rolling region of the pump on the suction side.Type: GrantFiled: June 25, 2018Date of Patent: May 24, 2022Assignee: Vitesco Technologies GmbHInventors: Johannes Deichmann, Tim Gonnermann, Norbert Fernau, Bernd Jäger

Patent number: 11306715Abstract: A screw-spindle pump includes: a first (drive) screw spindle and a second (running) screw spindle that runs oppositely with respect to the first screw spindle; and a pump housing configured to receive the first and second screw spindles. The first and second screw spindles form, together with at least the pump housing, delivery chambers, which move from a suction side of the pump to a pressure side of the pump due to a rotation of the first and second screw spindles. The pump housing has a first abutment insert for the first screw spindle and a second abutment insert for the second screw spindle, and at least one of the first and second abutment inserts is set angled with respect to a first plane of the pump, to counteract operationally induced crossing of the first and second screw spindles.Type: GrantFiled: June 25, 2018Date of Patent: April 19, 2022Assignee: Vitesco Technologies GmbHInventors: Johannes Deichmann, Tim Gonnermann, Marc Völker

Patent number: 11293433Abstract: A screw-spindle pump comprising: first and second screw spindles forming running and drive spindles, respectively, and a pump housing configured to receive the first and second screw spindles. The first and second screw spindles form, with at least the pump housing, delivery chambers, moving from a suction side to a pressure side of the pump as a consequence due to rotation of the screw spindles. The pump housing has an elongate insert, as an abutment for the first and second screw spindles and against which the first and second screw spindles are supported, the elongate insert having a first portion forming a first abutment for the second screw spindle and a second portion forming a second abutment for the first screw spindle.

Patent number: 7862310Abstract: The invention relates to a pump module (2) comprising a housing part (4) with precisely determined force introduction points (25) in relation to adjacent components. Supporting elements (24, 27) and a groove (26) are located between the force introduction points (25) and a disc element (20) that comprises a partially annular channel (10). Forces that are introduced into the housing parts (4) thus lead to negligible deformations in the areas of said housing parts (4) that are adjacent to the impeller.Type: GrantFiled: August 2, 2004Date of Patent: January 4, 2011Assignee: Siemens AktiengesellschaftInventors: Johannes Deichmann, Eberhard Geissel, Sven Kretschmar, Zlatko Penzar

Publication number: 20100218747Abstract: A fuel pump for delivering fuel from a reservoir to an internal combustion engine. The pump includes a casing, at least one impeller arranged in the casing. The impeller including at least one ring of interspaced vanes. The pump further includes an electric motor that drives the impeller via a shaft and that is configured as an axial field motor and that has a rotor and a stator. The rotor of said electric motor has permanent magnets and the coil formers carrying windings that are opposite the permanent magnets are stationarily arranged in the stator at a distance to the rotor axis and at even angular distances. The coil formers are arranged in parallel to the shaft of the electric motor with respect to their longitudinal orientation.Type: ApplicationFiled: September 24, 2008Publication date: September 2, 2010Inventor: Johannes Deichmann

Publication number: 20100189543Abstract: A fuel pump for delivering fuel in a motor vehicle, having a side channel stage. The fuel pump further includes a peripheral stage. The peripheral stage produces the same pressure at lower volume flow across the periphery of the rotor as compared to a side channel stage. For this purpose, the cross-sections of the delivery compartments of the peripheral stage are smaller than the cross-sections of the delivery compartments of the side channel stage. The fuel pump therefore has a higher efficiency and is less susceptible to soiling.Type: ApplicationFiled: May 15, 2008Publication date: July 29, 2010Applicant: CONTINENTAL AUTOMOTIVE GMBHInventors: Johannes Deichmann, Matthias Fischer, Bernd Jaeger

Patent number: 7708533Abstract: A fuel pump unit comprising a housing part (4) arranged between an electric motor (2) and a fuel pump (3). The housing part is provided with expansion joints for compensating thermal expansions or swelling of the material of the housing part (4). The gap between the impeller (6) and the housing parts (4, 5) of the fuel pump (3) can be kept constant by virture of the expansion joints, whereby the fuel pump (3) is essentially prevented from jamming especially when it runs dry.Type: GrantFiled: July 28, 2004Date of Patent: May 4, 2010Assignee: Siemens AktiengesellschaftInventors: Johannes Deichmann, Bernd Jaeger, Christoph Schmidt

Patent number: 7497656Abstract: The invention relates to a supply pump embodied as a side channel pump, whereby several sections (14-16) forming the cross-section of a supply chamber (13) each comprise radii. The origins of the external radii are arranged on the front face of a pump housing facing the one rotor. The sections (14-16) comprise common tangents in the adjacent regions thereof. A particularly high efficiency for the supply pump can thus be guaranteed.Type: GrantFiled: August 29, 2002Date of Patent: March 3, 2009Assignee: Siemens AktiengesellschaftInventors: Sabine Burhenne, Johannes Deichmann, Bernd Jaeger, Karsten Meiser

Patent number: 7473069Abstract: In a fuel pump (6) designed as a side channel pump, in each case two conveying chambers (20-23) one surrounding the other concentrically are arranged on two impellers (9, 10). The conveying chambers (20, 21) of one impeller (9) are connected to an inlet duct (25), while the conveying chambers (22, 23) of the other impeller (10) are connected to an outlet duct (26). A connection (24) of the conveying chambers (20-23) is arranged in a partition (17) keeping the impellers (9, 10) at a distance from one another. As a result, the fuel pump (6) has an especially high volume flow, along with a very high conveying pressure.Type: GrantFiled: September 7, 2004Date of Patent: January 6, 2009Assignee: Siemens AktiengesellschaftInventors: Johannes Deichmann, Eberhard Geissel, Bernd Jaeger
