Abstract
The present invention relates to a valve, especially for slip-controlled brake systems in automotive vehicles, with a valve tappet guided in a valve housing and including a valve closure member, with a valve seat facing the valve closure member, and with a piezoelectric element for actuating the valve closure member. A first and a second force transmission element is arranged between the piezoelectric element and the valve tappet, wherein the first force transmission element is made of a high-strength material that elastically deforms the second force transmission element in the direction of the valve tappet when the piezoelectric element is activated electrically.
