摘要:
A valve for controlling fluids, in which the valve member is adjusted by means of an actuating piston, which, together with a piezoelectric actuator piston, encloses a pressure chamber. In addition, the actuator piston and an affiliated piezoelectric stack are disposed in parallel radially next to the actuating piston, wherein upon excitation of the piezoelectric stack or adjustment of the actuator piston, the actuating piston executes a motion counter to the adjusting movement, and with its valve member, opens a relief bore.
