摘要： An electric coolant pump (1) conveys cooling fluid in order to cool a combustion engine of a vehicle. The electric coolant pump (1) has a pump impeller (2) for accelerating the coolant to be conveyed, a rotor shaft (3) on which the pump impeller (2) is fixed, an electric motor (6), having a stator (8) and a rotor (7), for driving the rotor shaft (3). A control circuit (13) controls the electric motor (6). A pump housing (10) accommodates at least the control circuit (13) and the electric motor (6). The coolant to be conveyed is able to flow through the pump housing (10). The coolant to be conveyed thereby flows around the stator (8), the rotor (6) and the control circuit (13).

摘要： The invention relates to a mechanically driven coolant pump having a controllable delivery rate for a main delivery circuit from a first outlet and for a secondary delivery circuit from a second outlet of the coolant pump, said coolant pump comprising, among other things, a hydraulic control circuit which is derived from the coolant pump and has an input-side auxiliary pump, an output-side proportional valve, and a regulating slide as a hydraulic actuator for limiting the flow of the main delivery circuit, wherein a cylindrical portion of the regulating slide can be axially displaced in the pump chamber in order to radially shield the pump impeller, specifically by means of a pressure in the hydraulic control circuit counter to a restoring force. The coolant pump is characterised in particular in that a regulating valve is connected to the hydraulic control circuit as a hydraulic actuator in order to limit the flow of the secondary delivery circuit, wherein actuations of the regulating slide and of the regulating valve are associated with pressure ranges in the hydraulic control circuit.

摘要： A gerotor pump includes a rotor wherein only on the face wall of the rotor that lies adjacent to a pressure kidney and a suction kidney, a lubrication surface inclined in the direction of rotation of the rotor, relative to the surface plane of the face wall of the rotor, is disposed on each tooth, in each instance, over its tooth height, either starting directly in the center tooth plane or starting “offset” ahead of the center tooth plane in the direction of rotation of the rotor, which surface is formed from a level surface or multiple, always level partial surfaces that follow one another, which enclose an angle of inclination relative to the surface plane of the face wall of the rotor, in each instance, which angle lies in the range from 0.2° to 7°, in each instance.

摘要： A coolant pump for an internal combustion engine (ICE) in a vehicle with a central engine control, having a pump shaft that drives an impeller for pumping a coolant. An axial piston pump operated via a wobble plate on a rear face of the impeller, conducts part of the pumped coolant away to a hydraulic circuit that extends from the axial piston pump via a proportional valve back to the pumped coolant and has a branch-off between the axial piston pump and the proportional valve as the hydraulic actuator. A regulating slide valve adjusts coolant volume flow of depending on pressure in the hydraulic circuit. A sensor detects a parameter characteristic of the coolant volume flow and outputs an actual value signal. A dedicated pump control controls the proportional valve based on the actual value signal of the sensor and a desired value signal of the central engine control.

摘要： A shaft bearing with a shaft seal, in particular for water pumps in motor vehicles, arranges a special radial shaft seal inside the outer bearing ring. The seal is made up of a stable rear wall arranged at a certain distance from the water-side of the shaft seal and fixed in the outer bearing ring, a secondary lip seal adjacent to a water-side of the rear wall, a support body solidly fixed in position in the outer bearing ring and adjacent to the secondary lip seal and a primary lip seal fixed in position adjacent to the support body on the water side, i.e. on the pressure side and opposite to the support body as well as opposite the outer bearing ring. Leakage openings are also arranged in the outer bearing ring, between the water-sided shaft seal of the shaft bearing and the rear wall which is arranged at a distance therefrom.
