<p>The three way distributing valve, together with the servo valve, is adaptable to the pressure medium flow vol. involved. The valve assembly is contained in the housing and comprises positioning units kept normally in the bottom position in a chamber by springs. The chambers are closed by covers with control line connections having lines connected to the servo valve. If the servo valve is shifted to the left, one valve position becomes operative. The control medium reaches the chamber and a positioning element rises against the spring force, while the non return valve remains closed.</p> |
