Abstract:
PCT No. PCT/EP96/01809 Sec. 371 Date Jan. 26, 1998 Sec. 102(e) Date Jan. 26, 1998 PCT Filed May 2, 1996 PCT Pub. No. WO97/06357 PCT Pub. Date Feb. 20, 1997Apparatus (1) for selective actuation of at least one gas exchange valve includes two members (2, 3) which can be selectively coupled through radially moveable coupling element (7), thereby facilitating the return flow of the hydraulic fluid acting upon the coupling element (7) in the direction of displacement especially at low ambient temperatures of the internal combustion engine and thus highly viscous hydraulic fluid. According to the invention, a relief channel (20) with an orifice plate (18) is installed in the return channel. With an orifice plate (18) of this type, the volume flow rate of the hydraulic fluid is largely independent of the viscosity, so that the coupling element (7) can be reset sufficiently fast even at low ambient temperatures.
