Abstract

APARATO BOMBEADOR DE COMBUSTIBLE CON DISTRIBUIDOR ROTATIVO QUE TIENE UN MANGUITO QUE SE PUEDE MOVER AXIALMENTE SOBRE EL DISTRIBUIDOR PARA AJUSTAR LA CANTIDAD DE COMBUSTIBLE SUMINISTRADO POR EL APARATO. EL MANGUITO ESTA CONECTADO POR UN EXTREMO A UN PRIMER NIVEL (46) MONTADO CENTRALMENTE SOBRE UN EJE (47). EL PRIMER NIVEL ESTA INCLINADO POR UN MUELLE QUE LO DIRIGE EN UNA DIRECCION POR UN DISPOSITIVO DE RESPUESTA DE VELOCIDAD. EL OTRO EXTREMO DEL PRIMER NIVEL (46) SE PUEDE ENGANCHAR A UN SEGUNDO NIVEL CENTRAL (50) CERCA DE SU EJE DE PIVOTAMIENTO (51) FORMANDO UN TOPE DE COMBUSTIBLE MAXIMO. LA POSICION DEL SEGUNDO NIVEL (50) PUEDE SER AJUSTADA POR UN TERCER NIVEL (54) SUJETO POR EL SEGUNDO NIVEL, EN EL MEDIO DE SU EXTREMO. LOS EXTREMOS DEL TERCER NIVEL SE CONECTAN A UNOS DISPOSITIVOS OPERABLES POR FLUIDO PRESURIZADO, SENSIBLES A LOS PARAMETROS OPERATIVOS DEL MOTOR, DONDE SE AJUSTA EL TOPE DE COMBUSTIBLE MAXIMO DE ACUERDO CON ESOS PARAMETROS.FUEL PUMP APPARATUS WITH ROTARY DISTRIBUTOR WHICH HAS A SLEEVE THAT CAN BE MOVED AXIALLY OVER THE DISTRIBUTOR TO ADJUST THE AMOUNT OF FUEL SUPPLIED BY THE APPLIANCE. THE SLEEVE IS CONNECTED BY AN END TO A FIRST LEVEL (46) MOUNTED CENTRALLY ON A SHAFT (47). THE FIRST LEVEL IS INCLINED BY A SPRING THAT DIRECTS IT IN A DIRECTION BY A SPEED RESPONSE DEVICE. THE OTHER END OF THE FIRST LEVEL (46) MAY BE HITCHED TO A SECOND CENTRAL LEVEL (50) NEAR ITS PIVOTING AXLE (51) FORMING A MAXIMUM FUEL STOP. THE POSITION OF THE SECOND LEVEL (50) CAN BE ADJUSTED BY A THIRD LEVEL (54) SUBJECT BY THE SECOND LEVEL, IN THE MIDDLE OF ITS END. THE THIRD LEVEL ENDS ARE CONNECTED TO PRESSURIZED FLUID OPERABLE DEVICES, SENSITIVE TO THE OPERATING PARAMETERS OF THE ENGINE, WHERE THE MAXIMUM FUEL CAP IS ADJUSTED IN ACCORDANCE WITH THOSE PARAMETERS.
