Abstract

UN TIPO DE DISTRIBUIDOR GIRATORIO DE APARATO DE BOMBEO DE COMBUSTIBLE TIENE UN MIEMBRO DISTRIBUIDOR (10) QUE MONTA BOMBAS DE PISTONES (14) ACCIONADAS POR LEVAS. DURANTE EL MOVIMIENTO HACIA DENTRO DE LOS PISTONES UNA VALVULA OPERABLE ELECTROMAGNETICAMENTE (32) FUNCIONA DE TAL MODO QUE CUANDO SE ABRE PERMITE QUE EL COMBUSTIBLE BAJO PRESION ABRA UNA VALVULA DE DESCARGA (31). LA VALVULA DE DESCARGA INCLUYE UN PISTON CARGADO POR RESORTE (23) QUE TIENE UNA PROYECCION (22) ENGANCHABLE CON UN ASIENTO PARA IMPEDIR EL ESCAPE DE COMBUSTIBLE DE LA CAMARA DE BOMBEO. SE PEMITE QUE EL COMBUSTIBLE BAJO PRESION ACTUE SOBRE EL PISTON CUANDO SE ABRE LA VALVULA. EL PISTON ESTA EQUILIBRADO A PRESION MEDIANTE UNA CLAVIJA (27) QUE ES DESLIZABLE EN UNA PERFORACION (25) EN EL PISTON, ESTANDO CONECTADA LA PERFORACION MEDIANTE UN PASAJE (26) A LA CAMARA DE BOMBEO. LA CLAVIJA SE MANTIENE LIBRE DE MOVIMIENTOS Y SU DIAMETRO ES SUBSTANCIALMENTE IGUAL AL AREA DE ASIENTO PARA ALCANZAR EL EQUILIBRIO DE PRESION.
