IMPLOSION NON-EXPANDABLE PRESSURE HYDROGENERATOR Russian patent published in 2017 - IPC E21B43/25 E21B37/00 E21B28/00 F16F5/00 

FIELD: oil and gas industry.

SUBSTANCE: implosion pressure hydrogenerator comprises a suction pipe with holes for supplying drilling fluid tank pressure, an implosion chamber cylinder, a plunger, an operating chamber, a hydraulic shock absorber. The cylinder chamber is connected to sub implosion with the intake manifold with a crossover sub. The plunger is connected to the sucker rod. The operating chamber comprises an operating cylinder with ports and pressure concentrators, an gate valve with the rod and the sleeve of the gate valve connecting the implosion chamber cylinder to the operating chamber. The hydraulic shock absorber comprises a cylinder with drain ports, a coil compression spring, a piston integral with the rod of the gate valve and assisted with the coil compression spring, a sleeve with a rigid spring stop interacting with the rod of the gate valve to avoid ultimate deflection of the coil compression spring. The implosion pressure hydrogenerator is provided with discharge chamber with chamber's air pressure equal to the atmospheric pressure, wherein the cavity is formed by a implosion chamber cylinder and by cylindrical body, sealingly mounted on the sleeve of the gate valve and on the adapter sub of the intake manifold, provided with sealing elements.

EFFECT: improved durability and operational reliability of implosion pressure hydrogenerator.
