FIELD: hydraulic pumping systems.
SUBSTANCE: invention can be used in hydraulic pumping systems. The inertial pressure multiplier based on a hydrodiode in oscillating hydraulic engineering systems consists of a shut-off valve (1), a check valve (2), two-half-period hydrodiodes (5), a filter (6), a check valve (8), a shut-off valve (9). Two-half-period hydrodiodes (5) are connected in series in a cascade. The hydraulic accumulator (3) is turned on at the outlet.
EFFECT: increase in the pressure developed by the hydrodiode.
