FIELD: mining. ^ SUBSTANCE: depth sampler consists of ballast chamber, of actuator with module of control, of main and additional sample taking chambers equipped with medium-separating pistons, hydro-resistors and valve units. Each medium-separating piston is equipped with a compensating tube, which connects under-piston cavities of sampling chambers between them. Also hydro-resistor is assembled at the end of each tube. ^ EFFECT: simplification and upgraded efficiency of operation of units of device, decreased dimensions of sampler, improved quality of separation of taken samples, and validity of measured information. ^ 1 dwg |
