Abstract
An impact action mechanism of the type wherein the impact member is propelled by a combustible matter combusted in the combustion chamber of the mechanism. The impact action mechanism includes a hollow housing receiving therein a reciprocating impact member and a sleeve connected with the housing. The impact member has a tail portion receivable in the sleeve to define therewith, as the impact member moves into the sleeve, a closed combustion chamber. This combustion chamber communicates with the ambient atmosphere for exhaust of the combustion products and with a source of a combustible matter, respectively, through a pair of passages formed through the bottom of the sleeve. The impact action mechanism is small in size in the transverse section and offers a simple structure, which permits its utilization in the mining and construction industries, as well as for driving through holes in soil.
