Abstract

EL SOPORTE (14) DE ELEMENTO DE CHAPALETA ELASTICO (2) DEL CONJUNTO DE VALVULA DE DISTRIBUCION COMPRENDE UNA ZONA DE EXTREMIDAD INTERIOR (26) QUE SE EXTIENDE RADIALMENTE EN LAS PROXIMIDADES DE LA PARTE ACTIVA ANULAR FRONTAL (4) DEL ELEMENTO DE CHAPALETA (2) Y QUE FORMA ANTERIORMENTE APOYO PARA UNA ARANDELA ELASTICA (32) QUE CONSTITUYE EL RESORTE DE CHAPALETA, Y POSTERIORMENTE APOYO PARA EL RESORTE (28) DE RECUPERACION DEL VASTAGO DE ENTRADA (8) DEL SERVOMOTOR. LA ZONA DE EXTREMIDAD INTERIOR (26) ESTA CONSTITUIDA VENTAJOSAMENTE POR UNA PARTE ANTERIOR (15) DEL SOPORTE DE ELEMENTO DE CHAPALETA MONTADO SOBRE UN CANALON (19, 20, 21) QUE RECIBE LA PARTE DE MONTAJE EXTERIOR (13) DEL ELEMENTO DE CHAPALETA (2) Y FORMADO POR UNA PARTE POSTERIOR (16) DEL SOPORTE DE ELEMENTO DE CHAPALETA MONTADO EN LA EXTREMIDAD POSTERIOR (17) DEL CUBO TUBULAR (1). SE PROPORCIONA ASI UN CONJUNTO DE VALVULA DE DISTRIBUCION DEL TIPOANTERIORMENTE CITADO, DE CONCEPCION FIABLE, ROBUSTA Y RECOGIDA, DE BAJOS COSTES DE FABRICACION Y QUE PERMITA UNA DISPERSION MENOR DE LAS CARACTERISTICAS DE LOS RESORTES PARA UNA FRABRICACION EN GRAN SERIE.
