ABSTRACT:
The invention relates to a valve system (1) with at least one valve body (2) and a longitudinal slide (3) slidably dispsoed therein which establishes or disrupts a connection between a feed line (4) and at least one inlet (5, 6) or outlet (7, 8) in the valve body92). The valve system further comprises an electrochemically driven actuator (9) that displaces the longitudinal slide. The aim of the invention is to improve the valve system by simplifying the design of the valve body and the longitudinal slide and to provide a secure and reproducible connection between the inlet/outlet and the feed line in order to feed a corresponding actuating device with a hydraulic fluid. To this end, the longitudinal slide (30has a longitudinal bore (10) connected to the feed line (4), which can be linked with the inlet (5, 6) or outlet (7, 8) via at least one connecting line (11, 12) that substantially extends radially outward from the longitudinal bore by displacing the longitudinal slide (3) by means of the actuator (9).
