Abstract: A spring clamp for plugging onto an electrical conductor of an electric machine, having a first spring leg and a second spring leg adjoining the first spring leg. The spring legs are arranged and/or formed with respect to one another in such a way that a receiving opening for receiving the electrical conductor is formed between a free first end portion of the first spring leg and a free second end portion of the second spring leg, and the conductor is clamped between the first end portion and the second end portion. The second spring leg has a sensor holder and a spring arm with a press-on tab, a spring force is exerted by way of the spring arm such that a sensor arranged in the sensor holder is fixed in the sensor holder by way of the press-on tab, and the sensor holder is pressed onto the electrical conductor.

Abstract: Various embodiments include an isolation ring for isolating the end windings of a stator of an electrical machine, the isolation ring comprising: a protrusion with a conductor guide for receiving a conductor, wherein the protrusion comprises: a pressing flap with an inner guiding surface; and a pocket with a temperature sensor arranged in the pocket. The inner guiding surface faces the pocket. The pressing flap and the pocket are arranged so an end of the conductor inserted in the conductor guide is guided between the inner guiding surface and the temperature sensor, and the end is pressed against and/or guided to the temperature sensor.

Abstract: A high pressure pump of a common rail pump system includes a pump body having a cylinder with a piston bore and a piston reciprocally driven in the piston bore to pressurize fuel in the cylinder. The piston has an inner end located in the piston bore and an outer end outside the piston bore. A bellow having a first opening and a second opening is arranged between the piston and the pump body, wherein the piston extends through the first and second openings, wherein the bellow is connected to the pump body such that the first opening is sealed on the pump body and wherein the bellow is connected to the outer end of the piston such that the second opening is sealed on the piston. This arrangement prevents mixing of engine oil and fuel. The bellow may be connected to a drainage line via a one-way valve.

Abstract: A high pressure pump for delivering a fluid includes a pump housing with a longitudinal axis and a housing cavity, a piston partly arranged in the housing cavity and axially moveable within the housing cavity and having an axial end directed opposite a driving side of the high pressure pump, and a sealing unit having a sealing body arranged radially outside of the piston such that a first part of the housing cavity is sealed fluid-tight against a second part of the housing cavity. The sealing body includes a neck with an inner diameter smaller than a first diameter of a part of the piston arranged between the sealing body neck and the axial end of the piston. The piston has a second diameter in an axial area in which the sealing body neck is arranged, which second diameter is smaller than the first diameter.
