This article is dedicated to a theoretical analysis of the influence of geometrical and mechanical parameters of the direct action flow regulator used in LRE on its static and dynamic characteristics. The investigation was conducted using a lumped-parameter mathematical model. It was showed, that the region dependently of the pressure drop in flow regulator, which the static characteristic is positive, is expanded when using the triangular geometry for the orifices of regulation, which is very important, specially, for multi-regimes LRE. For this geometric form orifice, the hydraulic force, which depends of the flow rate and the pressure drop in these orifices, and the thickness of the slide valve, have less influence in the positive behavior of the static characteristic of the regulator. The dynamic characteristics of the flow regulator, calculated in the technical system, are widely defined by the area of the piston and the area of the damping orifices.
regulator, static characteristic, hydraulic force, slide valve.
