  • Reversible pneumatic percussive device for making holes in ground by compaction
    Patent number: 3995702
    Abstract: A device has a cylindrical housing with a pointed front portion, which accommodates a striker separating the inner space of the housing to form a front and rear active chambers. The striker is provided with an open space at the rear end face thereof which mounts an air distributing branch connection threaded in the housing to be axially displaceable therein for reversing the device motion and adapted to admit compressed air to the active chambers and discharge it to the atmosphere therefrom thus reciprocating the striker which applies impacts to the housing. The air distributing branch connection has pipes arranged coaxially and forming longitudinal passages, of which the central passage serves to admit compressed air to the active chambers, while the annular passage between the pipes is used to discharge spent air from the active chambers.
