Abstract

EN EL CUERPO (10) DE VALVULA, UN PISTON (25) ESTA UNIDO AL ACCIONADOR (23) Y ES SOLIDARIO DE TOPES (30) QUE, MAS ALLA DE UN PRIMER RECORRIDO DEL PISTON (25), A PARTIR DE SU POSICION CONTRA EL ASIENTO (27), ARRASTRAN TOPES (19) SOLIDARIOS DEL OTRO PISTON (15), PARA ARRASTRARLO CON EL PISTON (25) SOBRE UN SEGUNDO RECORRIDO, A PARTIR DE SU POSICION CONTRA EL ASIENTO (14), DE MANERA A ALIMENTAR LOS INYECTORES ASISTIDOS POR AIRE POR LA SALIDA (31) SOBRE EL PRIMER RECORRIDO, Y EN ADMITIR ADEMAS AIRE EN DERIVACION POR LA SALIDA (32) SOBRE LA MARIPOSA (8), SOBRE EL SEGUNDO RECORRIDO. EL CONTROL DE UN UNICO ACCIONADOR (23) PERMITE REGULAR LOS CAUDALES DE AIRE SUCESIVAMENTE POR SUS DOS SALIDAS (31, 32). APLICACION EN EL EQUIPAMIENTO DE LAS INSTALACIONES DE ALIMENTACION DE COMBUSTIBLE POR INYECCION DE MOTORES DE COMBUSTION INTERNA CON INYECTORES ASISTIDOS POR AIRE.
