Abstract (en)
[origin: WO9103627A1] Hydraulic valve control device for internal combustion engines with a storage magnetic valve (31) to control the volume in a stroke transmission chamber (29) in order thereby to control the time cross-section of the motor valve (10), in which the magnetic valve (31) is currentlessly closed and the valve member constructed as a storage piston (41) is loaded by a storage spring (45) acting as a closing spring.
