Control device for hydraulic and/or mechanical components

摘要

A control device for hydraulic, mechanical, and hydraulic-mechanical components has a housing in which at least one drive element is arranged. The drive element is a piezo element having a voltage-dependent stroke-force behavior. The piezo element acts directly onto the component to be actuated. The control device with the piezo element replaces actuating devices such as solenoids, complete valves, as well as coupling and switching mechanisms.
