Abstract

UN RESORTE DE GAS QUE TIENE UN PISTON (34) ALTERNATIVO EN UNA CAMARA (14) DE UN BASTIDOR (16), UN CONJUNTO HERMETICO (18) EN EL EXTREMO FRONTAL DEL BASTIDOR A TRAVES DEL CUAL LA BARRA DE PISTON (20) SE EXTIENDE, Y UNA CAPERUZA DE EXTREMO (22) QUE CIERRA EL EXTREMO POSTERIOR DEL BASTIDOR. EL CONJUNTO HERMETICO (18) TIENE UN ANILLO DE REFUERZO (44) QUE TIENE UN ANILLO HERMETICO (46) Y LA LEVA (48) SON PARTES DE UN UNICO CUERPO DE MATERIAL ELASTOMERICO MOLDEADO HACIA EL ANILLO DE REFUERZO (44) Y SOLIDARIAMENTE CONECTADO A TRAVES DE UNA O MAS ABERTURAS (54) EN EL ANILLO DE REFUERZO (44). LA PARED DEL BASTIDOR ESTA LAMINADA RADIALMENTE HACIA EL INTERIOR SOBRE EL CONJUNTO HERMETICO (18) EN CONTACTO A PRESION CON EL ANILLO DE REFUERZO (44) DE MANERA QUE EL CONJUNTO HERMETICO SE CONVIERTA DE HECHO EN UNA CAPERUZA DEL EXTREMO PARA EL EXTREMO FRONTAL DEL BASTIDOR. EL EXTREMO POSTERIOR DEL BASTIDOR ESTA LAMINADO SOBRE LA CAPERUZA DE EXTREMO POSTERIOR (22) POR ESTAMPADO EN CONTACTO A PRESION CON LA CAPERUZA DEL EXTREMO. UNA VALVULA DE RELLENO (96) ESTA DISPUESTA EN LA CAPERUZA DEL EXTREMO. AL USARSE, EL PISTON (34) QUE ESTA NORMALMENTE SUJETO A LA BARRA (20) POR UN ENSANCHAMIENTO (32, 126) QUE TIENE UN MAYOR DIAMETRO QUE EL ORIFICIO DEL SOPORTE DE BARRA (36) DE MANERA QUE EN CASO INOPORTUNO EL PISTON SEPARA DE LA BARRA EL ENSANCHAMIENTO Y SE EMPOTRA EN EL SOPORTE (36) PARA SUJETAR LA BARRA EN EL BASTIDOR SI EL PISTON SEPARA DE LA BARRA UN ORIFICIO (130) EN LA BARRA EXPULSA A LA ATMOSFERA GAS COMPRIMIDO EN LA CAMARA.
