Abstract

A change-over valve device 1 serves to connect one or other of two or more feed means A, B, loan actuating means C, each feed means A, B, as well as the actuating means C, comprising pressure line and return line for the fluid acting as pressure medium, and comprises a slide or valve body 5 cooperating with the walls 2, 3, 4 of a cavity in the valve itself, said valve body 5 comprising pressure areas which are pressurized on actuation of one of said two or more feed means A, B, whereby said valve body is forced in that position which connects said one feed means with said actuating means C. In a modification, one flow line of each feed means A, B and of the actuating means C opens into one cavity within the valve housing, while the other flow lines open into a second cavity. The flow through each cavity is controlled by interconnected pistons which are activated as before by the input pressure from one or other of the feed means A, B. <IMAGE>
