Abstract

EL CUERPO (38) DE UNA VALVULA DE CONTROL (19) ESTA ALOJADO DENTRO DEL CUERPO HUECO (11) DE UN INYECTOR (10) POR MEDIO DE UNA CONEXION IMPERMEABLE A LOS LIQUIDOS QUE CONSTE DE UN PAR DE SUPERFICIES DE PRECISION DE ACOPLAMIENTO A TIERRA (70, 72), Y UN ANILLO DE CIERRE (75, 80) COMPRIMIDO ENTRE DOS SUPERFICIES MAS (40, 73; 78, 76) DE LOS CUERPOS (71, 38) ADYACENTES AL PAR DE SUPERFICIES ANTES MENCIONADO (70, 72). EL ANILLO (75) PUEDE ESTAR FABRICADO DE CAUCHO, PUEDE ACOPLARSE ENTRE DOS SUPERFICIES CILINDRICAS (40, 73), Y TAMBIEN ESTA PRESIONADO POR EL COMBUSTIBLE SOBRE UNA PESTAÑA (74) DEL CUERPO DE LA VALVULA (38). ALTERNATIVAMENTE, EL ANILLO PUEDE CONSISTIR EN UNA ARANDELA DE HIERRO BLANDO (80) PRESIONADA AXIALMENTE ENTRE UNA SOLAPA (42) EN EL CUERPO DE LA VALVULA (38) Y UNA SUPERFICIE (78) DEL CUERPO HUECO (11).
