Abstract: A piston pump, in particular a high-pressure fuel pump for an injection system of an internal combustion engine, has a piston and a working chamber which is delimited by the piston. The piston has a running surface section, via which the piston is guided with a guide element, and is configured and developed in such a way that the running surface section of the piston tapers in cross section towards its end which faces the working chamber.

Abstract: A charger device may include a variable turbine geometry having guide vanes mounted rotatably in a van bearing ring. Each guide vane may have a top side that runs in convex fashion from a profile nose to a profile end. A concave recess may be arranged on a bottom side of each guide vane at the profile nose.

Abstract: A charging device may include an actuating device for actuating a control device. The actuating device may be coupled to the control device via an actuating rod. The actuating rod may be coupled to the control device via a guide piece rotatably mounted at two points in an outer actuator lever.

Abstract: A turbine for a supercharging device of an internal combustion engine may include a control device for performance control of the turbine. The control device may include at least one actuator, which is pivotably mounted about a pivot axis relative to a turbine housing. The actuator may have a bearing shaft, which is mounted in a bearing of the turbine housing. The bearing shaft may include at least one bearing sleeve, which is radially in contact with the bearing.

Abstract: A supercharger device, including, at least one of a variable turbine and a compressor geometry; a guide vane device arranged in a housing, wherein the guide vane device includes at least one vane mounting ring; at least one guide vane is at least one of rotatably mounted thereon the vane mounting ring and rotatably mounted therein the vane mounting ring; and an adjusting ring arranged coaxially to the vane mounting ring and mounted on the latter, which is rotated relative to the vane mounting ring.

Abstract: The invention relates to a charging device, more preferably an exhaust gas turbocharger for a motor vehicle with a variable turbine/compressor geometry (1) with a plurality of adjustable guide blades, which are each engaged with an adjusting ring (2) via a corresponding lever (3, 3?) and which are preferentially jointly adjustable through said adjusting ring. Through a reinforcement (10) of a plurality of engagement regions (7, 7?) of the adjusting ring (2) which are in contact with an adjusting lever (3, 3?) each, higher force transmission from the adjusting ring (2) to the adjusting levers (3, 3?) is made possible without disadvantageous plastic deformation of the adjusting ring (2) or of the adjusting levers (3, 3?).

Abstract: An exhaust gas turbocharger, including either a variable turbine with rotatably mounted guide vanes or a compressor geometry with rotatably mounted guide vanes. At least one of the guide vanes has a profile center line with at least one of a jump and a kink.

Abstract: An exhaust-driven turbocharger for a motor vehicle may include a bearing housing and a turbine housing, which are mounted in the bearing house by means of a common shaft. A guide vane cage surrounds the turbine wheel. The guide vane cage may have at least two arms. The arms may be used to help secure the guide vane cage between the bearing housing and the turbine housing such that it can move in the radial direction.
