Abstract

UNA SERVOVALVULA ELECTROHIDRAULICA COMPRENDE UN PAR MOTOR (10) QUE RECIBE UNA SEÑAL ELECTRICA Y POSICIONA UNA VALVULA DE DISCO EXTERIOR (11) ENTRE UN PAR DE INYECTORES OPUESTOS (12) PARA CONTROLAR UNA VALVULA DE CARRETE (16) Y UN MUELLE DE REALIMENTACION (14) CONECTADO A LA VALVULA DE DISCO EXTERIOR (11) Y AL CARRETE (15) DE LA VALVULA DE CARRETE (16). LA VALVULA DE DISCO EXTERIOR (11) ESTA CONECTADA A UNA ARMADURA (20) DEL PAR MOTOR (10). LA UNION ENTRE LA VALVULA DE DISCO EXTERIOR (11) Y LA ARMADURA (20) COMPRENDE UNA PARTE ADHESIVA (A) DE COLOCACION TERMICA TRATADA A CALOR.
