Feasibility Study of a Novel Sleeve Type Switching Valve
Sprache des Titels:
Digital hydraulics became an area of high interest in the last years. Its success depends heavily on cheap and fast
switching valves which feature also compact design, low leakage, low electrical current and power requirements,
and easy integration into the hydraulic system. This paper presents a feasibility study of a novel magnetically
actuated, two coil, bistable 3/2 way sleeve type seat valve. The applicability of the valve was analysed by
analytical models, a prototypal design, by measurements of the prototype, and by CFD simulation of flow forces.
The sleeve concept turned out to have several inherent problems: insufficient closing-capability due to pressure
forces and a pressure dependent clamping of the sleeve; some leakage because of manufacturing tolerances of
the contact surfaces, and a complex design with many precise and costly parts to obtain compactness.
