Zusammenfassung:	FIELD: oil producing industry; mechanical engineering. ^ SUBSTANCE: proposed device is designed for use in submersible electrohydraulically-driven plants operating in marginal wells with complicated characteristics of oil bearing bed. Proposed hydraulic distributor contains spools, cylindrical housing with covers butt joining with flanges of power and return hydraulic cylinders. Middle rod connects pistons of hydraulic cylinders by means of joints. Additional control spool is introduced into hydraulic distributor. Pusher provides displacement of control spools at changing over. Control spools are arranged in one housing and are provided with slots. End faces of main spool are provided with channels accommodating throttles. Middle rod has throttles and slots. ^ EFFECT: provision of high quality of transient processes in hydraulic drive with working pump plunger reciprocating mechanism containing power and return hydraulic cylinders in system. ^ 2 dwg
