Abstract
L'invention concerne les constructions mécaniques. L'engin pneumatique faisant l'objet de l'invention est du type comprenant un creux 1 dans la cavité duquel est monté un percuteur 2 mobile en va-et-vient et agissant sur l'outil de travail de l'engin, et est caractérisé en ce que le tiroir 4 est réalisé sous forme d'un boîtier dont le fond en forme de cône tronqué est orienté dans le sens opposé au percuteur 2, le clapet 6 étant logé dans ce boîtier de manière à y former une chambre 14 avec laquelle communique un canal d'étranglement pratiqué dans le corps du tiroir. L'engin en question est destiné à être utilisé notamment dans le génie minier, l'industrie du bâtiment, etc.
