The invention relates to an electric drive (), in particular an electric motor of an engine-cooling fan or of an ABS/ESP of a motor vehicle, comprising an electric connector () and a housing (), in the interior () of which a drive assembly () is arranged. The electric connector () has at least one electric line () contacting the drive assembly (), an opening () is formed on the housing () for guiding through the electric line (), and a seal () is arranged in the region of the housing opening (). The electric line () has a first portion () and a second portion (), the first portion () having a conductor () mid a sheath () encasing the conductor (), and the second portion () being formed as an exposed conductor (), the electric connector () having a sleeve-like element () in which the second portion () is arranged at least in part. According to the invention, the sleeve-like element () is connected in a fluid-tight manner to the second portion () and the seal () bears at least partially against the sleeve-like element (), and the electric conductor () in the direction of its extent () is fluid-tight with respect to the housing interior () in the region of the sleeve-like element ().

The invention relates to a method () for electrically contact-connecting a winding () of an electrical machine () to a printed circuit board (), wherein the electrical machine () has an armature () with a large number of teeth (), wherein at least one winding (), which is formed by an electrical conductor (), is formed on one of the teeth (). The method comprises the following steps: routing () the conductor ends () of the electrical conductor () out of the armature () in the axial direction of the electrical machine (), shortening () the conductor ends () to the same length, routing () the conductor ends () through in each case one passage opening () in a centring element (), wherein the centring element () has a centring means () which centres and orients in parallel the routed-through conductor ends (), wherein the routed-through conductor ends () emerge from the centring element (), routing () the conductor ends () through in each case one passage opening () in a sealing element (), wherein the routed-through conductor ends () emerge from the sealing element (), inserting () the centring means () into in each case one passage opening () in a sealing element (), arranging () the sealing element () at least partially within a passage opening () in a housing element (), and electrically contact-connecting () the conductor ends () to the printed circuit board ().

The invention relates to a device for at least intermittently generating an overpressure in a system S in relation to an ambient pressure U, with a pump P that has a pressure sideand an intake side, where during the generation of an overpressure, the pressure sideis connected to the system S and the intake sideis connected to the ambient pressure by means of at least one first valve MV, in particular a solenoid valve. According to the invention, means are provided, which can provide an additional cross section for the intake volume flow during the generation of an overpressure. The invention also relates to a valve, which is particularly provided for use with the device according to the invention.

Overpressure generator and valve

A device for at least intermittently generating an overpressure in a system S in relation to an ambient pressure U includes a pump P that has a pressure side and an intake side where during the generation of an overpressure, the pressure side is connected to the system S and the intake side is connected to the ambient pressure by means of at least one first valve MV , in particular a solenoid valve. At least one additional valve (ZV) is provided, which is connected in parallel to the first valve MV and can provide an additional cross section for the intake volume flow during the generation of an overpressure.

Positive pressure generation device and valve

In a process and a device for measuring a throttle point, a fluid under pressure is applied to the throttle point by a pump, at least one operating parameter of the pump is acquired and stored, at least two reference operating parameters of two reference throttles are acquired and stored, and the operating parameters are compared with a reference operating parameters in an evaluating unit and a throttle magnitude is outputted.
