摘要

A valve device includes a valve housing with at least one inlet channel and an outlet channel. A valve piston can be moved axially in the valve housing and has control edges for releasing and blocking the connection between the cross sections of the inlet and outlet channels. A regulating device applies the actuating force to the valve piston. Elements produce a force opposing the actuating force through at least a part (a proportional area) of the overall working range of the valve device, depending on the pressure in the outlet channel.
