Patent number: 11466789Abstract: 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.Type: GrantFiled: November 15, 2019Date of Patent: October 11, 2022Assignee: Schaeffler Technologies AG & Co. KGInventors: Lukas Kuhn, Horst Hartmann, Georg Draser

Patent number: 8425123Abstract: 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.Type: GrantFiled: April 14, 2008Date of Patent: April 23, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8235597Abstract: 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.Type: GrantFiled: January 15, 2010Date of Patent: August 7, 2012Assignee: Schaeffler Technologies AG & Co.
