Publication number: 20060046060Abstract: A process for producing a wear-resistant coating and a wear-resistant coating on a surfaces of machine or engine parts which are exposed to frictional wear. This has in particular use for internal combustion engines. The coating comprises at least one metal-free, amorphous hydrocarbon layer which includes sp2- and sp3-hybridized carbon applied to the surface of the machine part, for reducing friction and increasing the wear resistance of the surface of the machine or engine part.Type: ApplicationFiled: August 24, 2005Publication date: March 2, 2006Inventors: Bodo Rorig, Tim Hosenfeldt

Patent number: 6976461Abstract: The invention proposes a switchable finger lever (1) for a valve train of an internal combustion engine having a compact structure. Through the inner lever (5) of the finger lever (1) it is possible, on the one hand, to realize a support on a gas exchange valve and, on the other hand, a mounting on a head of a support element. An outer lever (2) surrounds the inner lever (5) in longitudinal direction with its arms (3a, 3b) and is pivoted away from the inner lever (5) for effecting uncoupling. The outer lever (2) is mounted for pivoting on a cross axle (14) that extends through the inner element (5) axially above the support (8) for the gas exchange valve. At the same time, coupling elements (6) displaceable in crosswise direction are arranged axially above a complementary surface (9) that serves as a support on the support element.Type: GrantFiled: June 10, 2005Date of Patent: December 20, 2005Assignee: Ina-Schaeffler KGInventors: Bodo Rörig, Michael Haas

Patent number: 6655333Abstract: In a valve train of an internal combustion engine having a switchable support element (1), the lost motion spring (18) of the support element (1) is arranged axially offset next to the support element (1) while being coupled to an inner element (3) of the support element (1) by a crossbar (20). Due to this externally positioned spring (18), the support element (1) requires only a relatively small design space.Type: GrantFiled: November 29, 2001Date of Patent: December 2, 2003Assignee: Ina Walzlager Schaeffler oHGInventors: Joachim Seitz, Michael Haas, Bodo Rörig, Dicter Schmidt

Patent number: 6460495Abstract: In a switchable support element (1) for a valve train of an internal combustion engine, the lost motion spring (8) of the valve train is made as a torsion spring. This spring is arranged outside of the support element (1) and only the legs and the arms of the spring engage a housing and a head, respectively. In this way, the support element (1) requires no substantially larger design space than non-switchable prior art elements, particularly in axial direction.Type: GrantFiled: December 3, 2001Date of Patent: October 8, 2002Assignee: Ina Walzlager Schaeffler oHGInventors: Joachim Seitz, Dieter Schmidt, Michael Haas, Bodo Rörig

Patent number: 6425358Abstract: A switchable, hydraulic support element (1) requiring only a small design space is proposed. For achieving this, a bore (16) for a slide (23) is arranged laterally of a pressure piston (10) of a hydraulic clearance compensation element (11) in the inner element (7) and is configured as a pocket bore. This dispenses with the stacked arrangement of the bore in the inner element and the clearance compensation element on top of each other as seen in prior art. At the same time, the slide (23) is installed in a housing (19) that extends in the cylinder head (5).Type: GrantFiled: September 5, 2001Date of Patent: July 30, 2002Assignee: Ina Walzlager Schaeffler oHGInventors: Michael Haas, Bodo Rörig, Dieter Schmidt, Joachim Seitz
