  • Device for making holes in soil
    Patent number: 4785898
    Abstract: The invention relates to the construction equipment. A device comprises a body (1) internally accommodating a percussion member (2) with ports (5), an air distributing sleeve (6), an elastic element (7) and a threaded bushing (8). Grooves (9) are made on an external surface of the threaded bushing (8) at an angle to the axis of the device. When the device is moving soil gets in the grooves (9) of the threaded bushing (8) and develops a circumferential force fixing the threaded bushing (8) relative to the body (1).

  • Reversible percussive action machine
    Patent number: 4697647
    Abstract: A reversible percussive action machine includes a housing accommodating a mmer capable of reciprocating motions under the action of a working fluid under pressure, and a valving member with grooves movably connected to the hammer and provided with members for fixing it relative to the housing in two distribution control positions, particularly one that makes the machine move forward and one that ensures the return travel of the machine. The members for fixing the valving member in a position for the forward travel of the machine is fashioned as an insert movable relative to the valving member and having projections received by the grooves of the valving member. The insert is enclosed by a shell with ports, this shell being secured between the housing and the valving member to be capable of axial displacement.

  • Reversible, percussive device for ground perforation
    Patent number: 4171727
    Abstract: A reversible ground perforating device powered by a gaseous medium under ssure, comprising a hollow cylindrical body with a pointed front end. The body accommodates a hammer adapted to reciprocate therein. A front power chamber of variable volume is formed by the hammer in the body. The rear end of the hammer has a cylindrical hollow which forms a rear power chamber of variable volume. The power chambers are interconnected by means of ports provided in the hammer. A stepped cylindrical barrel is located inside the cylindrical hollow in the hammer and coaxially therewith. The barrel is secured in the rear end of the body and the large-diameter portion of the barrel is arranged to interact with the hammer. The wall of the large-diameter portion of the barrel has ports. A spring-loaded stepped sleeve is mounted coaxially with the stepped barrel so that the large-diameter portion of the sleeve is adapted to cover the ports in the barrel.
