FIELD: production of oil from wells where agreement of inflow of formation fluid to well and pump output is required. SUBSTANCE: hydraulic transmission used as adjustable device consists of hydraulic pump at adjustable angle of inclination of wobble plate and hydraulic motor. Inclination of wobble plate is adjusted through movable plunger resting against wobble plate of hydraulic pump on one side and compressed spring resting against rod connected with wobble plate of hydraulic pump on other side relative to axis of inclination of wobble plate. EFFECT: extended fields of application and range of control of rotational speed of submersible electric motors of well pumps. 3 dwg
