    摘要: A reversible percussive action machine comprises a housing which accommods a hammer capable of reciprocating motions under the action of a pressurized fluid, and a fluid valving member for controlling the distribution of fluid with parts for fixing it in two fluid control positions to assure either the forward or rearward percussive action of the machine. To fix the fluid valving member to provide for the forward percussive action of the machine, a spring-loaded insert which is movably secured relative to the valving member and engageable with a stop made in the housing is used. To fix the fluid valving member in a position to provide for the rearward percussive action of the machine, a stop made on the inside wall of the housing and a stop made in the valving member to engage with the stop of the housing is used. The insert is fashioned as a cup accommodating an element imparting a spring action on the cup relative to the fluid valving member.

    摘要: An air-operated reversible percussive action machine comprises a housing (1) accommodating a reciprocating hammer (2). Secured inside the housing (1) is a stepped tube (5). The step of larger diameter of the tube (5) is received by a cavity (4) of the hammer (2) and has a port (12) for distributing air flow and feeding it to the interior of the housing (1). The tube (5) receives a sleeve (14) having a port (15) alternately communicable with the port (12) of the tube (5) in one of its two positions. One end face of the tube (5) has a projection (13) in the form of a sector of a circle, whereas the sleeve (14) is provided with a radial projection (16) so that in turning the sleeve (14) its projection (16) bears on one of the side walls of the projection (13) of the sleeve (5) thus assuming one of the two positions.

    摘要: 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. The space between the large-diameter portions of the sleeve and barrel forms an annular chamber. Holes are provided in the sleeve small-diameter portion interacting with the barrel small-diameter portion. A ring is flexedly mounted in the large-diameter portion of the barrel in the front end thereof and coaxially therewith. The space between the ring, the inner surface of the barrel and the outer surface of the sleeve forms an auxiliary annular chamber. The annular chamber is in communication with the source of a compressed gaseous medium during forward movement of the ground perforating device, whereas the auxiliary annular chamber is in communication with this source during reverse movement of the device.
