Abstract

LA INVENCION SE REFIERE A UN CONJUNTO, FORMADO POR UNA PARTE POR UN SERVOMOTOR, QUE LLEVA UNA ENVOLTURA (20) FIJADA SOBRE EL TABLERO (10) DEL VEHICULO, Y SEPARADO DE MANERA ESTANCA POR UNA PARED MOVIL (22) EN UNA CAMARA DELANTERA (24) CONECTADA PERMANENTEMENTE A UNA FUENTE DE DEPRESION Y UNA CAMARA TRASERA (26) CONECTADA SELECTIVAMENTE A LA CAMARA DELANTERA (24) O A LA ATMOSFERA POR UN MEDIO DE VALVULA 816) ACCIONADO POR UNA VARILLA DE CONTROL 814) PARA ACCIONAR UNA VARILLA DE EMPUJE (28), Y POR OTRA PARTE POR UN CILINDRO PRINCIPAL (200) QUE LLEVA UN CUERPO (210) FORMADO CON AL MENOS DOS BRIDAS DE FIJACION (38, 48, 40, 40'') DEL CILINDRO PRINCIPAL (200) SOBRE LA ENVOLTURA (20) DEL SERVOMOTOR (100), CADA UNA COOPERANDO CON UN TORNILLO Y UNA TUERCA, DESLIZANDOSE AL MENOS UN PISTON (32) EN UN ESCARIADO (34) DEL CILINDRO PRINCIPAL (200), Y SIENDO ACCIONADO POR LA VARILLA E EMPUJE (28). SEGUN LA INVENCION, SE PREVEN UNOS MEDIOS (60, 60'') PARA QUE UNA ROTACION DEL CILINDRO PRINCIPAL (200) RESPECTOAL SEVOMOTOR (100) BAJO EL EFECTO DE UN PAR DE ROTACION APLICADO AL CILINDRO PRINCIPAL (200) DURANTE UN ESFUERZO IMPORTANTE DE ESTE ULTIMO, PROVOCA LA INTERRUPCION DE LA CONEXION MECANICA ENTRE EL PISTON (32) DEL CILINDRO PRINCIPAL (200) Y LA VARILLA DE EMPUJE (28) DEL SERVOMOTOR (100).
