Hydraulic valve drive

The hydraulic drive has a hydraulic synchronising piston (12,121) with a drive chamber. There is a valve piston (13,13') driven hydraulically by the drive chamber for each valve (11,11') to be driven so that the valve pistons move synchronously. A damping device (124) dampens the return of...

Beschreibung
Zusammenfassung:	The hydraulic drive has a hydraulic synchronising piston (12,121) with a drive chamber. There is a valve piston (13,13') driven hydraulically by the drive chamber for each valve (11,11') to be driven so that the valve pistons move synchronously. A damping device (124) dampens the return of the synchronising pistons and valves into their starting position. A hydraulic device (1) compensates differences in the overhang (H,H') of the shafts of the two or more valves driven with the hydraulic drive.
