A guide ring for a pump element of a hydraulic unit of a vehicle brake system is configured to guide a pump piston in a pump housing when the pump piston is displaced along the axis thereof in the pump housing. On the inner side of the guide ring facing the pump piston, the guide ring includes a first step that has a first inner diameter and a second inner diameter.

An arrangement for throttling a fluid flow includes a throttle element arranged so as to influence a flow cross section in a fluid duct. The throttle element has a resiliently elastic disc-shaped basic body which is arranged with a top side and a bottom side between at least two supports in the fluid duct. The body is arranged in such a way that the flow cross section can be variably adjusted as a function of a pressure difference between the top side and the bottom side of the resiliently elastic disc-shaped basic body. At least one support bears against the top side of the resiliently elastic disc-shaped basic body, and at least one support bears against the bottom side of the resiliently elastic disc-shaped basic body.

A piston pump, in particular for a hydraulic assembly of an electronically controllable vehicle brake system, includes a cylinder element that has a pressure chamber with an outlet formed on the inside. The piston pump further includes an outlet-restricting element held on the outside of the cylinder element on a component by a first holder.

A linear drive, in particular for a piston pump, includes a first electromagnetic drive device, a second electromagnetic drive device, and a drive piston configured to be moved in an axial direction by the drive devices. The first drive device and the second drive device are each in the form of a reluctance drive device. The reluctance drive devices each have a stator with a stator coil that engages around the drive piston in a circumferential direction. The reluctance drive devices each also have a coil core with a coil receptacle, open in a radial direction toward the drive piston, for the coil winding. A piston pump arrangement includes the linear drive.

A spring element includes a disc-shaped basic body, in which at least one spring bridge is inserted. The basic body has at least one dynamic throttle point to throttle a fluid flow. The basic body has a resilient configuration in a region of the at least one throttle point. Accordingly, an opening cross section of the at least one throttle point is configured to be set variably depending on a pressure difference.

A sealing ring, in particular for a hydraulic piston pump, for sealing a pressure chamber which is filled with a fluid is disclosed. A sealing lip having a contour contacts a sealing surface and is movable relative thereto. The contour of the sealing lip is adapted according to the speed of the sealing lip relative to the sealing surface, such that a defined leakage of the fluid out of the pressure chamber is adjusted.

In a frictional transmission having at least one rolling contact element, which is guided in frictional engagement between two running surfaces and is furthermore guided by a cage, one of the running surfaces is arranged in a fixed location and the second running surface and the cage are embodied so as to rotate in such a way that an input torque can be introduced via one of the elements, namely the cage or the second running surface, and an output torque can be output via the other element, namely the second running surface or the cage.

A hydraulically controlled accumulator-chamber valve has a closing element and a tappet. The closing element is prestressed via a first compression spring and seals a valve seat in a valve body. The tappet reaches through a leadthrough in the valve body and is moved by an accumulator piston. The accumulator piston is loaded by a second compression spring. The tappet is moved to press the closing element out of the valve seat when there is a specified balance of forces between the spring prestressing forces and a hydraulically active force. The closing element and the tappet are configured as a single-piece component, in order to guide the tappet in the leadthrough in a longitudinally movable manner. The tappet bears against an end face of the accumulator piston during an opening movement.
