摘要:
A hydraulic valve tappet for an internal-combustion engine has a high-pressure valve through which an electroviscous fluid flows as a function of an electric voltage. In this case, a piston is displaced which is connected with a charge cycle valve so that the valve stroke is continuously variable. Using an electronic control device, the valve stroke is influenced as a function of parameters of the internal-combustion engine.
