Abstract

Mejoras en mecanismos neumáticos de impacto, comprendiendo un miembro de trabajo guiado oscilablemente en una carcasa y equilibrado entre un muelle y una cámara de trabajo aprovisionada con aire comprimido, estando definida esta última por la porción extrema trasera del miembro de trabajo, un miembro de soporte de reacción y un elemento de empaquetadura elástico, alojado entre el miembro de trabajo y el miembro de soporte de reacción, caracterizadas porque el elemento de empaquetadura comprende un collar de válvula anular, extendido axialmente, que es radialmente expansible por la presión de aire en la cámara de trabajo hacia un diámetro exterior que excede de su diámetro exterior nominal, porque el miembro de soporte de reacción comprende una depresión situada coaxialmente con dicho collar de válvula, teniendo dicha depresión una pared periférica interior de un diámetro que excede del diámetro exterior nominal de dicho collar de válvula, por lo que dicho collar de válvula, durante cada ciclo de oscilación del miembro de trabajo, entra en dicha depresión, y por expansión radial en la misma establece una empaquetadura hermética al aire con dicha pared periférica.
