Abstract
An electro-fluidic signal converter has a body provided with an inlet and two outlets for pressure fluid. The body is composed of a pair of outer non-magnetic plates and a plurality of laminated-together inner magnetizable plates which are fluid-tightly sandwiched between the outer plates. The inner plates have respective plate portions which together constitute a body section that is resiliently deflectable out of a neutral position, and this body section is formed with a fluid channel which communicates with the inlet and has a discharge orifice that communicates equally with both of the outlets when the body section is in its neutral position. An electromagnet is located adjacent the body and is energizable to thereby deflect the body section out of its neutral position to one of a plurality of operated positions in which the discharge orifice communicates preferentially with one of the outlets. A method of making the body is also disclosed.
