The valve device consists, according to the invention, of (at least) two part valves which are symmetrical in circuit terms with respect to the existing connections and which are designed, in particular, as four-way, two position valves of any desired type of construction, but preferably are provided as slide valves. There is preferably a double slide valve with two cooperating slide valves. The valve device features internal seals and sealing surfaces which minimize wear and damage to the seals as they move across flow ports. The valve device is particularly adapted for use as a fuel control valve for an internal combustion powered motor vehicle having two separate fuel tanks. The valve device permits control over which tank supplies fuel to the engine, and allows controlled mixing of the fuels from each tank.
A multiway valve arrangement for use as a fuel tank changeover valve between at least two fuel tanks and an engine in a motor vehicle, with at least two tank connections for each of the tanks, including a forward flow tank connection and a return flow tank connection and at least two engine connections including a forward flow engine connection and a return flow engine connection, the valve arrangement comprising at least two cooperating multiway four-way valves, symmetrical in circuit terms, enabling the forward flow tank connections to be connected alternatively or jointly to the forward flow engine connection and the return flow tank connections to be connected alternatively or jointly to the return flow engine connection.
