Abstract

MECANISMO DE VALVULA DE CONTROL DE CIRCULACION, APLICABLE A SERVO-DIRECCIONES, DE RESPUESTA A UNA DEMANDA. CONSTA DE UNA BOMBA (10) QUE ASPIRA FLUIDO A TRAVES DE UN PASO (12) DESDE UN DEPOSITO (14) QUE LO CONTIENE; DE UNA VALVULA DE CONTROL DE CIRCULACION (18) QUE ENTREGA EL FLUIDO EN UNA CANTIDAD PREDETERMINADA A UN SISTEMA OPERATIVO, TAL COMO UN MECANISMO DE SERVOD-IRECCION (20); DE UNA LUMBRERA DE DERIVACION (24) QUE DEVUELVE EL EXCESO DE FLUIDO AL DEPOSITO (14); DE UN SISTEMA OPERATIVO PROVISTO DE UN ORIFICIO VARIABLE (28) QUE SIRVE COMO ELEMENTO REGULADOR DE DEMANDA, PARA ESTABLECER LOS REQUERIMIENTOS DE NIVEL DE PRESION PARA LA BOMBA; Y DE VALVULAS DE RETENCION (50, 52) DISPUESTAS EN EL CARRETE DE VALVULA QUE RESPONDE A LA DIFERENCIA DE PRESION Y AL NIVEL DE PRESION DEL SISTEMA.
