A valve includes a valve housing, a piston, a support element, and a spring. The piston and the valve housing are arranged coaxially to each other on an imaginary valve axis. The piston is received in the valve housing in an axially movable manner against the spring force of the spring. The spring is supported on the support element and on the piston. The valve housing is provided with a first opening through which a fluid can flow and which can be closed by a piston base of the piston. The valve housing is provided with a second opening which can be at least partly closed by a piston casing of the piston and through which the fluid can flow. The piston casing extends outwards from the piston base in the axial direction of the support element and surrounds the valve axis.

Valve, method for producing a valve, and device for regulating the pressure of a fluid in a vehicle transmission, comprising a valve designed as a pressure compensation valve

A roller bearing () having a sleeve (), by which a rolling element raceway is formed, and a lid () held to the sleeve by a snap-on connection, wherein the lid has securing projections (), which are directed outward, which protrude beyond the sleeve () in the radial direction and are provided for axially fixing the lid in a housing () surrounding the sleeve.

Roller bearing

A device for conducting oil in a vehicle gearbox, wherein the device has at least two elements which can move with respect to one another and at least one sleeve made from steel plate, and the sleeve is arranged here between the elements and at least one of the elements and the sleeve are secured to one another in a positively locking manner, and wherein a first element of the elements is surrounded at least partially by the sleeve and a second element of the elements surrounds the sleeve and the first element at least partially.

Device for conducting oil in a vehicle gearbox with at least two elements which can move with respect to one another and with a sleeve

A device for transferring fluids between two elements arranged concentrically within one another, wherein there is a sleeve-shaped hollow-cylindrical first component arranged between the two elements having at least one through-hole for the fluid, wherein the first component is made of steel and sits in a first element, wherein the first component is prevented from turning around a symmetry axis of the first component by at least one safety element engaging form-fittingly in the first element, wherein the first element is at least partially made of a material having a greater coefficient of thermal expansion than the steel material, characterized by the fact that between the first component and the first element, a second hollow-cylindrical component is arranged concentric to the first component and that the second component is secured from turning around the symmetry axis by a safety element on the first element and the first component.

Device for transferring fluids

A radial needle bearing unit for supporting a shaft, which has an outer sleeve with at least one radially inwardly directed rim, and a cage guiding hearing needles. For sealing purposes, a sealing element is disposed in an annular space delimited by the rim and the cage. The sealing element is an outwardly expanding sealing ring made of a polymer material resting radially outwardly against the inner lateral surface of the outer sleeve and radially inwardly against the lateral surface of the shaft, so that a radial/radial seal is formed. The outer sleeve has, at least in one peripheral location, a holding lug which is formed by stamping or cutting and protrudes the lateral surface of the outer sleeve in a spring-loaded manner.

Radial needle bearing unit

A combined radial-axial rolling bearing for rotatably mounting a rotary body in the region of a diameter step. The rolling bearing has a radial bearing unit which is assigned to a circumferential surface of the rotary body and which at least has a radial bearing ring, and an axial bearing unit which is assigned to an axial surface of the rotary body and which at least has an axial bearing ring. To mount the rotary body radially in the region of the larger diameter, the radial bearing unit is assigned to a circumferential surface which has the larger diameter. The radially outer rim of the axial bearing ring is latched to a rim of the radial bearing ring which faces toward the radially outer rim, such that the two bearing rings form a structural unit which can be assembled in one work step, but otherwise remain functionally separate.

Combined radial-axial roller bearing

A coupling arrangement () with a first clamping ring () concentric to the axis of rotation (), a second clamping ring () oriented concentrically with the axis of rotation and grooved around its circumference, and with clamping bodies () oriented radially between the clamping rings (); which includes on at least one of the clamping rings projections () that are built into a shape like a ramp (), each of which is placed between two neighboring clamping bodies; and which includes a first retainer () and a second retainer (), with which the clamping rings () and the clamps () are held together.
