A hydraulic percussion device intended for the impact-fracturing of rock and synthetic materials. The present invention contains a housing, in which are installed centering bushings, sealing bushings, a sleeve and a piston-striker, forming, within the housing, working-stroke and return-stroke chambers, and also high-pressure and low-pressure hydraulic accumulators. The working stroke chamber communicates periodically by means of a piston valve distributor with a pressure line or with a low-pressure hydraulic accumulator which, in turn, communicates with a drain line. The return-stroke chamber is in constant communication with a high-pressure hydraulic accumulator and with a pressure line. A compression ring is installed on the piston of the striker. Drainage chambers and channels are provided between the centering and sealing bushings. A wall of the sleeve is provided with a start channel, which puts into communication, by means of the distributor, the working stroke chamber and the pressure line. The present invention decreases hydraulic resistance and the likelihood of leakages of liquid between chambers. The present invention allows for guaranteeing the initiation of the device at any initial position of the piston-striker.

The invention relates to construction. The structural panel comprises a core in the form of a layer of heat-insulating and/or sound-insulating material, flexible connecting members which pass through the core, and welded wire meshes, which are arranged on both sides of the core, parallel to the surfaces thereof and with a gap relative thereto. The flexible connecting members are in the form of ties passing through the core through parallel through-slots with a width equal to the width of the ties in terms of the outer measurements, said through-slots, formed in said core, being oriented perpendicular to the length of the structural panel and being arranged in rows along the panel. Rods of a working reinforcing assembly pass through the eyes of each row of ties, which project on both sides of the core. Fastening means for the rods of the working reinforcing assembly are mounted under each rod of the working reinforcing assembly along the entire length, in the gaps between the eyes of the ties on both sides of the core. The welded wire meshes are connected to the rods of the working reinforcing assembly on both sides of the core, parallel to the surfaces thereof. The invention improves the carrying capacity and reliability of the attachment of elements of the panel.
