ABSTRACT:
A multiple flow and direction control valve connectable to a plurality of separate fluid sources, the valve having a fluid power port and a fluid exhaust port and a first movable valve body being operable to add or subtract the flow rates of a plurality of fluid sources to either the power port or the exhaust port. The valve has a directional control member having two power ports and one exhaust port and being operable in a first position to apply power fluid to one of the power ports, exhaust fluid being returned through the second power port and routed out of the exhaust port and in a second position said power fluid being routed to the other power port and returned through the first power port to the exhaust port. The valve includes modified directional control members which may be stacked to sequentially provide directional control for a plurality of outputs. Both the multiple flow selection portion and the directional control portion provide for a constant fluid flow rate through the valve to either a power port or an exhaust port.
