Hydraulic servomotors testing station hydraulic system, comprised of a unit of mechanically joined servomotors, connected with their immobile part attached to the base, comprised of at least one servomotor being tested and at least one resistance servomotor, wherein working chambers of servomotors are connected with each other with two branches of conductors in such a manner that when a given branch is power supplied, the mobile element of tested cylinder tends to shift the element mechanically joining cylinders in the direction opposite to the direction of its movement driven by the resistance servomotor powered from this branch, characterised in that the element mechanically joining the tested servomotor (1) and the resistance servomotor (2) is a reciprocating engine, preferably in a form of hydraulic servomotor (3), or is mechanically connected to such engine, while branches connecting of the tested servomotor (1) and the resistance servomotor (2) working chambers are connected to the supply pump (6), through the controlling element (4), preferably a distribution valve, whereas during the reciprocating engine movement, one of the two branches connecting the tested servomotor (1) and the resistance servomotor (2) working chambers is always hydraulically connected with the pump (6), and the other branch is connected with the tank (10).<IMAGE>
