Abstract
A hydraulically operated valve with controlled lift, in particular a fuel/gas injection valve for internal combustion engines, has a stop face fixed on the valve stem. For accurate control of the opening of the valve a stop cam is provided, which is drivn mechanically via a friction clutch, and which cooperates with the stop face. By rotating the cam through a predetermined angle the maximum valve lift will be obtained. The cam may be brought into contact with the stop face even in the closed position of the valve.
