Internal combustion engine valve drive hydraulic tappet has rheological fluid pressure medium whose viscosity can be varied by external control effect, that is held in closed circuit by connecting channel between leakage gap, inlet opening
摘要
<p>The hydraulic tappet (1) has an cylindrical piston (3) in a cylindrical pot-shaped housing (2) and a pressure medium in the form of a rheological fluid whose viscosity can be varied by an external control effect and that is held in a closed circuit by a connecting channel (15) arranged between a leakage gap (11) and an inlet opening (9). An independent claim is also included for a method of controlling an inventive device.</p>
