The paper presents the results of experimental studies of hydraulic drive with throttle control. The fluid flow is considered in a flat slit-like throttle channel accompanied by the appearance of cavitation phenomena. The comparison of the results of the calculation of flow compression rate, performed on the basis of the jets theory in accordance with the procedure proposed by Professor S.S. Rudnev, is presented in the paper together with the values of the rate obtained by experimental methods. The study of the orifice coefficient for a flow with forming a closed cavity is conducted using an equivalent circuit.
