<p>A device for feeding and processing of pluging and cementing materials in a given section of a bore hole comprises a tubular container (1) rigidgly connected successively mounted to the string (2) of bore rods through a limiter (3) and a cylinder (4). The lower part of the tubular container (1) sealed with a plug (8) houses a splitter (7), whereas in its upper part above hydrosealing envelopes (5) is mounted movably along the tubular container (91) a main piston (9) with the rod (10) on which is fixed rigidly a stopper (11) interacting with the limiter (3) and an additional piston (12) mounted in the cylinder (4) movably along the latter and connected hydraulically to the string (2) of the bore rods. The stopper (11) is mounted on the rod (10) at such a distance from the main piston (9) as to ensure the fixation of the latter in its lowest position immediately above the splitter (7).</p> |
