FIELD: motors and pumps.
SUBSTANCE: invention contains control system, two cylinders with distribution valves and opposite moving piston groups. Each piston group contains piston, stock and armature of the linear motor. The linear motor includes stator magnet, two magnetic cores and two magnetising coils. The piston groups are oriented such that their axes of symmetry are located at one geometrical line, and their movement is arranged opposite thus excluding vibrations due to oscillating movement. But character of pistons movement is affected also by inaccuracy of the piston groups manufacturing, nonuniformity of friction forces between friction surfaces, unpredictable movement of pump-compressor etc. To synchronise movement of the piston groups the control system monitors speeds of each piston group and compares them. If speeds of the piston groups are different, the control system switches the distribution valve, via which the work body is supplied to the header, to closed position of the cylinder in which the piston group speed is higher then speed of the opposite moving piston group in another cylinder. At the time moment ensuring simultaneous arrival of the piston groups of both cylinders in points of convergence or divergence the control system switches the distribution valve to opened position.
EFFECT: casing vibrations are excluded.
