FIELD: engines and pumps.
SUBSTANCE: invention relates to hydroficated equipment. It can be used in machine building for control of whatever components in metallurgy, metal forming and cutting which required timed operation of hydraulic engine output links. Output links 3, 4 of displacement hydraulic drive of hydraulic engines 1, 2 are timed with working fluid fed from separate pump 9, 13 fed to each of them. Proposed process consists in that portion of working fluid from pump pressure fluid forced to hydraulic engine with output link advancing is transferred into pump pressure line that feeds hydraulic engine. Output of link of the latter lagging behind features direction and magnitude flow rate changed by extra reversing motor-pump 14 in proportion to departure of difference in coordinates of output links 3, 4 of hydraulic motors 1, 2 from preset magnitude.
EFFECT: lower production costs.
