Abstract: The development of a proportional electro-fluidic pneumatic valve is presented. The first stage of the valve consists of a piezoelectric bender element of bimorph construction centered between ...

Abstract: The effects of geometry, Reynolds number, and wall temperature on the separation of a fluid jet from a curved surface are investigated. The results are used to develop an electropneumatic ...

Abstract: The effects of nonuniform error quantization on feedback control system stability from the viewpoint of the existence of limit cycles are discussed. The existence of limit cycle is investigated ...

Abstract: A flow model of a three-way underlapped hydraulic servovalve is presented and used to derive a mathematical description of the flow momentum forces acting on the valve spool. The effect of ...

Abstract: The development of an electro-fluid fourway on-off pneumatic valve is described. The design utilizes two permanent magnet valving elements between ferromagnetic nozzles; coils around the nozzles ...
