    摘要: A pump includes an electric motor with a rotor rotatably mounted about an axis of rotation and circumferentially surrounding a stator. The stator includes a stator core and coils wound on the stator core. The coils are made from a winding wire with winding wire end sections electrically contacted at an end surface with a printed circuit board. The winding wire end sections, starting from the stator, extend radially outwardly to the axis of rotation and are directly contacted with the printed circuit board via insulation displacement contacts.

    摘要: A damping element (1) has a multi-start thread on its circumferential surface (4). The damping element (1) can engage in a recess in a first body (12). To this end, the damping element (1) has a thread portion on its circumferential surface and the recess (13) in the first body (12) has in its inner lateral surface at least one mating thread portion which corresponds to the thread portion of the damping element (1). Through engagement of the thread in the mating thread, the damping element can be screwed together with the first body (12). By means of the thread, the damping element (1) can be fastened to the first body (12) and separated therefrom again with little effort. A fastening element (23) can fasten the damping element (1) to a second body in order to fasten the first (12) and the second bodies to one another in a vibration-damped manner.

    摘要: The present invention relates to a dry-running, oil-free orbiter vacuum pump, on which a friction-optimized surface is provided on components. The dry-running orbiter vacuum pump comprises inter alia a pump housing with a cylindrical pump chamber and an orbiter eccentric piston with a guide slot and a cylindrical exterior surface, a cylindrical cross-section of the orbiter eccentric piston being smaller than a cylindrical cross-section of the pump chamber. At at least one of a radial air gap and an axial air gap formed in the cylindrical pump chamber between the orbiter eccentric piston and the pump housing at least one sliding surface is arranged in a manner exposed to the air gap; wherein the at least one sliding surface comprises a microstructure including cavities for decreasing an exposed surface of the at least one sliding surface.

    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: 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.
