Patent number: 7096837Abstract: The invention proposes a valve train of an internal combustion engine comprising a cam (1) and a directly driven cam follower (2), such as a roller tappet. This valve train is additionally designed for effecting an internal exhaust gas recirculation at an exhaust valve.

Patent number: 7086360Abstract: The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets.Type: GrantFiled: January 16, 2004Date of Patent: August 8, 2006Assignee: Ina-Schaeffler KGInventors: Oliver Schnell, Christof Faria, Peter Sailer, Matthew Evans

Patent number: 7080614Abstract: A hydraulically actuated, preferably variable, valve drive of an internal-combustion engine is provided, with a slave unit (15), which is embodied as a separate component relative to a master unit. A special characteristic is that the slave unit is provided with a hydraulic backlash compensation element (9), which is connected to a path (12) for feeding hydraulic medium only outside of a stroke phase of a slave piston (5). As a result, on one hand an easy-to-produce valve drive with slave unit (15) is provided. On the other hand, unnecessary “pumping up” of the backlash compensation element (9) during the stroke phases of the slave piston (5) is prevented by the previously mentioned admission of hydraulic medium.Type: GrantFiled: November 30, 2004Date of Patent: July 25, 2006Assignee: INA-Schaeffler KGInventors: Martin Rauch, Michael Haas
