Actuator for electro-motive force and fluid pressure force

Claim 1

A control device having a single moving body controlling the application of both EMF and FPF in a system, comprising, a case having at least a first wall and a second wall, a single body in said case constituting said single moving body having at least a first surface and a second surface; said first and second body surfaces lying adjacent said case first and second walls respectively; means for moving said single body and said case relative to one another to locate said single body relative to said case in at least two positions, said case having at least one FPF supply port and at least one FPF use port in said first wall surmounted by means for making connections to FPF supply and use, said single body first surface movably sealing against said first ported wall of said case, said single body first surface having a grooved maze constituting at least two separate channels between said FPF supply and use ports with at least one said channel selectively communicating between FPF supply and use ports at one said position of said single body relative to said case to effect desired application of FPF in a system, said case having at least two sets of EMF contacts on said second wall, EMF terminals on said case leading to and from said contacts for connection to EMF supply and use; said single body second surface having a sliding bridge member for selectively making electrical connection between said sets of contacts for selectively actuating said EMF sets of contacts at one said position of said single body relative to said case to effect desired application of EMF in a system; the bridge member and contacts control of EMF and the channel and port control of FPF, both being coordinated in operating a system by the position of said single body relative to said case.
