Abstract

The invention relates to the mining industry and is intended to destroy rocks by a stream of water. The purpose of the invention is to increase the reliability of the device. The cock-in device includes an annular chamber (CC) 1, communicated through the drain window 2 with the cavity of the barrel 3, and the cylinder 5 with the piston 6 and the elastic element 7. The piston 6 is placed in the cylinder 5 with the formation of the piston cavity (P) 8 communicated with CC 1 , and zaporshnevoy P 9. In the end wall of the cylinder 5 on the side of zaporshnevoy P 9 there are holes 10 for supplying the working fluid. The elastic element 7 is located in podporshnevoy 8. Through the holes 10 serves under the pressure of the working fluid. The piston 6 compresses the elastic element 7 and displaces the water from the sub piston П 8 through КК 1 into the cavity of the barrel 3 and cocks the piston 4 of the impulse water jet. 1 il.

The invention relates to the mining industry and is intended to destroy rocks by a stream of water.

The goal of the app is to increase the reliability of the device operation.

The drawing shows the platoon device, a longitudinal section.

The cock-in device of the pulsed jet-gun comprises an annular chamber I, communicated through the drain ports 2 with the cavity of the barrel 3, in which the piston 4 is placed, and the cylinder 5 with the piston

6 and the elastic element 7. The piston 6 is placed in the cylinder 5 with the formation of the sub-piston cavity 8, reported

with an annular chamber 1, and a piston cavity 9, In the end wall of the cylinder 5 from the side of a piston cavity 9 there are holes 10 for supplying the working fluid. Elastic element

7 is located in the piston chamber 8.

The device works as follows.

Sub-piston cavity 8 is filled with water. Through the holes 10, the working fluid is supplied under pressure (for example, oil) into the zaporshnevuyu cavity 9. Under the pressure of the working fluid, the piston 6 compresses the elastic element 7 and displaces water from the piston

bore 8 through the drain window 2 into the cavity of the barrel 3 and cocks the piston 4 of the pulse jet. After charging the piston 4 holes 10 switch to drain the working fluid. Under the action of the flexible element 7, the piston 6 returns to its original position. Water from the cavity of the barrel 3 is discharged through the windows 2 into the Sub-piston cavity 8. After that, the piston 4 of the pulse jet is started up, and the cycle is repeated about
