ABSTRACT:
A device to control valves of an internal combustion engine, especially the gas supply valve of a gas engine, which can be operated by a piston of a working cylinder, which can be pressurized with a pressure medium against the return force of a spring. A control device, preferably designed as a control slide valve, which has a movable control apparatus by way of which a work space of the working cylinder can be pressurized with the pressure medium in order to open the valve and relieved in order to close the valve, is arranged before the piston on the pressurization side. The movable control apparatus can itself be controlled by an associated pilot control device. It is possible to control the opening timepoint and closing timepoint of the control valve independently of one another and independently of the inlet valve, because the control apparatus of the control device without a return spring can be brought into the position that pressurizes the steam space with pressure medium and, independently thereof, into the relief position by the pilot control device.
