Publication number: 20110105257Abstract: A mechanical tensioner for a traction drive element is provided. It includes a housing with a bore having an open end and a closed bottom. A plunger having a first end is located in the bore. The first end of the plunger has a tapered slot or tapered opening defined therein forming a hollow wall portion of the plunger.

Patent number: 7934478Abstract: A lubricant circuit of a camshaft adjuster is provided. In conventional camshaft adjusters, lubricant is supplied from a cylinder head to the camshaft adjuster via a supply channel (66) and a receiving channel (69), with an annular groove that encircles in a circumferential direction being located between the supply channel and the receiving channel in order to ensure a continuous lubricant supply. According to the invention, the lubricant is transferred from the supply channel to the receiving channel in a discontinuous manner. The omission of the encircling annular groove causes a discontinuous or cyclic flow of lubricant so that lubricant is transferred only when the supply channel (66) is at least partially aligned with the receiving channel (69).Type: GrantFiled: November 23, 2006Date of Patent: May 3, 2011Assignee: Schaeffler Technologies GmbH & Co.
