FIELD: oil and gas industry.SUBSTANCE: device consists of three chambers of different diameters connected by couplings. At that chambers represent cylindrical tubes. At the bottom of the second chamber there is a spring with large piston fixed on it. The large piston has valves. The valves are installed at connection sleeve between the first and second chamber. A small piston is installed in the third chamber. Small and large pistons are connected by rod assembly. In the third chamber there are through holes for liquid cross-flow at the angle more 45 degrees. The method includes usage of the above device. At that transmission is performed due to difference in volumes of chambers made of cylindrical tubes. Reverse motion of liquid is prevented by closure of valves under liquid pressure between the first and second chamber.EFFECT: higher operating reliability of the device and efficiency of the method.2 cl, 1 dwg |
