Air pulsing system

Claim 1

A system for converting air under constant pressure to a pulsating air flow wherein the air impulses at peak pressure are of a substantially greater pressure value than said constant pressure for driving of a motor, said system comprising, a pressure storage vessel, a series of air cylinders each of progressively greater volume adapted to receive an air charge in an alternating manner, piston means within each of said cylinders, compressible means associated with each of said pistons and actuated upon the downward stroke of its piston for the conservation of energy expended by the piston, an air transfer line extending intermediate the ends of each cylinder and a transfer valve in each of said lines, a fluid operated motor driven by the last cylinder of the series, high pressure conduits intercommunicating the upper ends of said cylinders to provide same with a source of pressurized air, the first cylinder of the series receiving air via a high pressure conduit from said storage vessel with the remaining cylinders of the series receiving air moving sequentially through said cylinders, inlet valves in said conduits admitting air under pressure to the upper ends of the cylinders for downward displacement of their pistons, exhaust valves also in said conduits permitting an exhaust of air from the upper ends of the cylinders during upward piston movement, low pressure conduits in communication with the lower ends of said cylinders and in communication with a source of low pressure air, valves in said low pressure conduits permitting a flow of low pressure air through said last mentioned conduits into the lower ends of the cylinders during upward travel of said pistons, and a control circuit simultaneously opening the inlet valve and transfer valve associated with each cylinder for admitting a flow of high pressure air and air transferred from the bottom side of the cylinder, said control circuit simultaneously closing the exhaust valve and the low pressure valve associated with each cylinder during the downstroke of the piston, said circuit operable additionally to simultaneously reserve the positions of the valves whereby the piston under the influence of low pressure air and said compressible means causes an impulse of air to be exhausted into the high pressure conduit and to a subsequent cylinder of the series with the piston of the last cylinder of the series operable to impart a force to a media for the operation of a motor.
