Control device for controlling the supply to an oscillating motor for driving a compressor unit of the resonant-type piston unit and a resonant type compressor piston provided with said control device.

摘要

ARISE a control device (30) for controlling the power supply to the coils (16A, 16B) of an engine (3) for a compressor unit piston type RESONTANTE (1). CONTROL DEVICE COMPRISING A POWER SUPPLY CIRCUIT (44) to supply power to the coils (16A, 16B) FROM MOTOR VOLTAGE SUPPLY DIRECT (45), means (46,47,48; 46,60) for determining a measure (P, (empty)), which indicates WHEN THE ENGINE POWER CONSUMPTION FREQUENCY AS A FUNCTION OF CURRENT power supply is close to the maximum, and means (40,42,43; 61,42 43) TO ADJUST THE FREQUENCY CURRENT POWER SUPPLY DEPENDING ON THE EXTENT RESULTING (P, (empty)) to a value for which the measure (P, (empty)) INDICATES THAT THE POWER CONSUMPTION OF MOTOR ( 3) it is maximum.
