Abstract: The working characteristics of a longitudinal flow hydraulic installation is largely determined by the interaction of operating elements with hydraulic flow. A salient feature of the studied device is the operative parts in the form of hollow cylinders with through-holes. Entering the flow, they fill with water, with their mass increasing. Leaving the flow, the cylinder becomes empty and its weight is equal to its proper weight. The process of increasing in the cylinder’s weight in its interaction with the flow can be regarded as manifestation of the "pseudo-reactive force". The research considers the features of this interaction for the movable operating elements of variable mass. An original solution is suggested for this problem of practical value and theoretical significance.
