FIELD: engines and pumps.
SUBSTANCE: synchroniser of movement of armatures-pistons in opposite phase of free piston pump-generator, which converts liquid flow energy to electric energy and electric energy to liquid flow energy, which includes control system, stator magnets, armatures-pistons, polarising coils of armatures-pistons, control valves of liquid flow; at that, movement synchronisation of armatures-pistons in opposite phase of pump-generator at difference of speed values of armatures-pistons of pump-generator is performed by decrease or interruption of current in one of polarising coils of armature-piston; for that purpose, at operation of pump-generator in generator mode the control system tracks the current speed values of each armature-piston and decreases or interrupts the current in polarising coil as per unbalance signal of speeds of armatures-pistons of that armature-piston the speed of which is less than speed of the other armature-piston, and at operation of pump-generator in pump mode the control system tracks the current speed value of each armature-piston and decreases or interrupts the current in polarising coil as per unbalanced signal of speeds of armatures-pistons of that armature-piston the speed of which is more than speed of the other armature-piston, and after armature-piston reaches the speed providing synchronous movement of armatures-pistons in opposite phase, the control system restores the circuit of polarising coil of armature-piston.
EFFECT: synchronous movement of armatures-pistons in opposite phase.
