Abstract
Perfeccionamientos en dispositivos de pistón de movimiento alternativo accionados por gas comprimido en particular para herramientas de percusión que incluye un tubo cilíndrico metálico en el cual oscila el pistón, estando empotrado el tubo cilíndrico en un manguito exterior no metálico en el cual se extiende al menos un conducto para gas comprimido, caracterizados porque se forma por un componente de cilindro compuesto que comprende un tubo cilíndrico metálico rígido, en el cual el pistón efectúa el movimiento alternativo al funcionar, y un manguito exterior moldeado de caucho o de material de plástico sintético y rodeando el tubo cilíndrico metálico al que se adhiere, superponiendose el manguito a toda la superficie circunferencial exterior de la parte principal de la longitud del tubo, y formándose el manguito en su superficie exterior con una pluralidad de nervaduras moldeadas íntegramente, proyectadas hacia fuera, dirigidas longitudinalmente, separadas alrededor de la circunferencia del manguito, comprendiendo el dispositivo además un silenciador tubular exterior, hecho de caucho o material de plástico sintético, que rodea al manguito nervado y define dentro del silenciador, cuya cámara se comunica con una abertura de escape que sale del silenciador, cuya cámara se comunica con una abertura de escape que sale del silenciador para la atmósfera ambiente, formandose el componente del cilindro por lo menos con un orificio de descarga de gas en su pared, que desemboca en la primera cámara del silenciador entre dos nervaduras adyacentes del silenciador de manguito, y donde se forma un conducto moldeado alargado, extendido longitudinalmente , en el interior de por lo menos una de las nervaduras, constituyendo el conducto un conducto de transferencia para suministrar gas comprimido a una parte extrema del interior del tubo cilíndrico.
