摘要： 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. The elongate insert is clamped into a receptacle of the pump housing using a cross-sectional dimension of the elongate insert.

摘要： A method determines an inflection point OP of a parameter profile i, n which is representative of a component tolerance and a state of wear of a fuel pump. The fuel pump is provided for a fuel supply system for use in a device equipped with an internal combustion engine. The device being a passenger car, utility vehicle and/or a stationary or mobile power generator.

摘要： A fuel conveying device having a pumping stage, an electric motor to drive the pumping stage, a control unit, a magnetoresistive fill level sensor that generates a fill level signal, including a temperature-effect compensator that generates a compensation signal to compensate for temperature-related influences on the fill level signal, and an evaluation unit (5) designed such that the temperature of a fluid surrounding the fill level sensor can be determined by the evaluation unit by the compensation signal. A fuel tank equipped with a fuel delivery device of said type, a method for determining the temperature of a fluid inside a fuel tank, a method for controlling and/or regulating an electric motor, and a method for controlling and/or regulating an injection of fuel vapors to a combustion process of an internal combustion engine.

摘要： A fuel pump includes: an electric motor; a pump stage drivable by the electric motor; and a fuel pump housing configured to accommodate the electric motor and the pump stage. The fuel pump housing has a first housing part configured to accommodate the electric motor and a second housing part configured to accommodate the pump stage. One or both of the first housing part and the second housing part are made of a conductive plastic adapted to dissipate static charges to a ground potential.

摘要： 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.
