Patent ID: 7605489

Claim:
An airflow power station comprising: a windmill engine rotatable by a wind airflow, said windmill engine including a main shaft and associated with a speed sensor measuring the rotational speed thereof; a compressed air storage means; an air compressor supplying compressed air into said storage means; at least one electric energy generator; a flywheel associated with the main shaft, said flywheel is capable of conveying rotation to said air compressor and to said at least one generator; and at least one pneumatic cylinder furnished with: a piston slidely disposed and capable of reciprocating therein, sensors sensing an initial and an ending positions of the piston, and a rod; a first end of said rod is coupled with said piston, a second end of said rod is hingedly coupled with a unidirectional clutch so mounted that is capable of a controllable engagement of said piston with and a controllable disengagement thereof from said flywheel at predetermined positions of said piston; said pneumo-cylinder is divided by its piston into an inner chamber, and an outer chamber; said outer chamber pneumatically communicates with said compressed air storage means via an intake valve capable of controllable supplying a predetermined dose of a compressed air flow from said storage means into said outer chamber and of controllable shutting the compressed air flow corresponding to said initial and ending positions of said piston, said intake valve is connected with a pneumo-regulator capable of controllable switching the supplied compressed air flow ‘on’ and ‘off’ depending on the rotational speed of said main shaft measured by said speed sensor; said pneumo-cylinder including a reverse spring disposed in the inner chamber thereof and capable to be compressed during a work stroke of said piston and to be released upon return of said piston into its said initial position.
