Abstract

LA INVENCION SE REFIERE A UN MECANISMO LINEAL (10) PARA UN TENSOR DE CINTURON, PROVISTO DE UN TUBO CILINDRICO (20) Y DE UN EMBOLO (22) QUE SE DESPLAZA EN EL INTERIOR DE ESTE Y QUE PRESENTA UNA CAVIDAD INTERIOR HUECA (24) Y UNA CARA FRONTAL (26) EN UNO DE LOS EXTREMOS DE SU EJE. LA CARA FRONTAL PRESENTA UN ORIFICIO DE PASO (40) Y UN DISCO DE EXPLOSION (42) EN LA CARA DE LA CAVIDAD INTERIOR (24) DEL EMBOLO (22). EL MECANISMO DE LA INVENCION DISPONE ASIMISMO DE UNA CARGA DE PROPULSION (28) PIROTECNICA QUE, TRAS SU IGNICION, INUNDA LA CAVIDAD INTERIOR (24) DEL EMBOLO (22) CON UN GAS A PRESION. EL MECANISMO SE CARACTERIZA PORQUE EL ORIFICIO DE PASO (40) ES UNA PERFORACION GRADUADA CON UNA PRIMERA SECCION (56) SOBRE LA CARA ORIENTADA HACIA LA CAVIDAD INTERIOR DEL EMBOLO Y UNA SEGUNDA SECCION (58) SOBRE LA CARA OPUESTA CON UN DIAMETRO MENOR QUE LA PRIMERA SECCION (56), ASI COMO PORQUE EL DISCO DE EXPLOSION (42) ESTA COLOCADO EN EL BORDE DE LA PRIMERA SECCION (56) DE LA PERFORACION GRADUADA SOBRE LA CARA INTERIOR DEL EMBOLO (22).
