Publication number: 20160017937Abstract: A rocker one-way clutch includes a stator housing, an inner race, and a strut. The stator housing has a strut pocket and a plurality of stator blades. The inner race has a first angled contact face. The strut is disposed in the strut pocket and has a second angled contact face arranged to contact the first angled contact face. In an example embodiment, an angle between a line passing from the contact face to a rocker pivot center and a line parallel to the contact face is acute. In an example embodiment, the acute angle is approximately 10 degrees.Type: ApplicationFiled: July 14, 2015Publication date: January 21, 2016Applicant: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 8561640Abstract: A hydraulic valve including an inlet port for receiving a pressurized hydraulic fluid and an outlet port for expelling the hydraulic fluid. The valve also includes a displaceable spool for blocking and unblocking a flow path between the inlet and outlet ports, and a latching mechanism for displacing the spool in response to a pressure surge for the hydraulic fluid. The valve includes a first elastic element and a second elastic element, where the first elastic element urges the spool into a position blocking the flow path and the second elastic element urges the latching mechanism to displace the spool into a position out of the flow path. In an unlatched position of the latching mechanism, force from the second elastic element is transferred to the spool, and in a latched position of the latching mechanism, the spool is isolated from the second elastic element.Type: GrantFiled: November 4, 2010Date of Patent: October 22, 2013Assignee: Schaeffler Technologies AG & Co.

Publication number: 20100206405Abstract: A hydraulic valve having a first fluid chamber hydraulically connected to a pressure source, a second fluid chamber hydraulically connected to a pressure operator, and a blocking member for controlling fluid flow between the first and second chambers. The blocking member substantially blocks fluid flow between the first and second chambers when a pressure of fluid in the first chamber is greater than a minimum pressure and less than a pressure of fluid in the second chamber. The blocking member is displaceable to enable fluid flow between the first and second chambers when the pressure of fluid in the first chamber is below the minimum pressure.Type: ApplicationFiled: February 10, 2010Publication date: August 19, 2010Applicant: LuK Lamellen und Kupplungsbau Beteiligungs KGInventor: Trevor MCCONNELL
