Abstract:
A shock absorber mounted electromagnetically operated damper valve for regulating the flow of fluid through the shock absorber to accommodate varying road conditions, said damper valve comprising:a housing having a wall defining a hollow interior having a first plurality of openings therethrough for the flow of fluid;a spool reciprocally mounted within said hollow interior and moveable between first and second positions responsive to electromagnetic energization for controlling the flow of fluid through said hollow interior and said first plurality of openings; anda retainer received within said hollow interior for controlling the motion of said spool at one of said first and second positions and defining a reduced diameter orifice in the flow path of said fluid, said reduced diameter orifice developing a differential pressure across said spool during flow of fluid through said valve to assist in retaining said spool in a predetermined one of said first and second positions in the absence of said electromagnetic energization.
