    摘要： The device comprises a hollow cylindrical body, pointed front at its end which device accommodates a striker forming the front working chamber in said body, and has a cylindrical space at its rear end. Said space receives an air-distributing and reversing mechanism, thus forming the rear working chamber. The air-distributing and reversing mechanism has a bushing which is fixed relative to the body, and an axially movable bushing, both bushings being arranged coaxially, spring-loaded in the axial direction relative to each other, and forming a chamber located in the front part of said mechanism, with the chamber communicating with a source of compressed air and intended to move the movable bushing during reversal of the device. The side wall of the movable bushing has a through hole and a longitudinal external recess, both made in such a manner that during the forward travel of the device the through hole places the chamber formed by the bushings in communication with the source of compressed air while during the backward travel the through hole is covered by the fixed bushing and the chamber formed by the bushings communicates with the atmosphere through the external longitudinal recess.

    摘要： A percussive action machine includes a housing in which a hammer is movably secured to define a forward stroke chamber and a return stroke chamber. The hammer is provided with an air-distributor fashioned as a sleeve having holes. The hammer is further provided with a device for alternately communicating the return stroke chamber with the forward stroke chamber and with the outside, the device having the form of at least one bore arranged inside the hammer in line with its axis. Communicating with this bore is a tubular control valve extending through the forward stroke chamber and having in its wall at least one hole wherethrough the return stroke chamber alternately communicates with the forward stroke chamber and with the outside.

    摘要： A pneumatic impact mechanism for driving rod-like members having a hollow cylindrical casing with a tail portion and a front end portion. The casing accommodates a reciprocating stepped hammer piston defining in the casing, on the tail portion side, a variable volume rear end work chamber in permanent communication with a source of compressed air. The stepped hammer piston defines, on the side of the front end portion, a variable volume front end work chamber.The stepped hammer piston has a through-passing axial bore, and its small-diameter portion cooperates with the tail portion of the casing and has radial passages. There is provided a tubular guide member or element for receiving the rod-like member arranged coaxially with the stepped hammer piston and casing and secured to the tail portion and to the front end portion of the casing in such a manner as to cooperate with the stepped hammer piston and define therewith, with the outer periphery thereof an axial passage. A clamp for engaging the individual rod-like members is rigidly removably secured to the front end portion of the casing. The front end-work chamber communicates, at regular intervals, with atmosphere through the axial passage and radial bores when the stepped hammer piston is in its rear end position and with the rear end work chamber when the stepped hammer piston is in the front end position to deliver blows to the casing under the action of compressed air fed to the work chambers.

    摘要： An air-operated reversible percussive action machine comprises a housing in which there is disposed for axial reciprocations a hammer, defining therewith a front working chamber and having a through radial passage. In the axial interior of the hammer on the side of its tail end there is provided a cylindrical stepped tube including coaxially arranged first and second steps of large and small diameters, respectively, these steps having through radial passages. The first step of the tube defines with the hammer a rear working chamber, and with the second step defines an annular cavity in which a spring sleeve capable of axial displacements is disposed. The outer diameter of the sleeve is substantially less than the inner diameter of the first step of the tube to form an annular passage there between. The machine is further provided with a means for pressure-sealing the annular cavity and a means for controlling the displacements of the sleeve.
