Abstract
Abstract An arrangement in which compressed air and fuel are intermixed and burned to release the energy in the fuel. The heat resulting from the combustion of fuel and compressed air is used to generate superheated steam. The superheated steam and products of combustion are intermixed within the combustion chamber, and the mixed gases are passed through a positive displacement motor and to a variable displacement motor which converts the energy in the gases into mechanical energy. A valve between the positive displacement motor and the second motor may be used to interrupt the mechanical output of the second motor, while retaining the gases within the combustion chamber in ready state for resuming the mechanical output upon subsequently displacing the valve to an open position.

Claim 1
Independent Claim
333 words
An energy conversion arrangement, comprising in combination, a combustion chamber; a source of compressed air connected to said chamber; a source of fuel connected to said chamber and mixed with said compressed air for combustion; a source of water and containing means in said chamber for receiving water to be converted into steam by the combustion of said fuel and air, said containing means isolating said water from contact with the interior of said combustion chamber and from contact with the products of combustion, said steam being released from said container means and passed into the interior of said chamber for intermixing with the products of combustion within said chamber; ring-shaped means for distributing said steam about the interior of said chamber for intermixing substantially uniformly with the products of combustion; first conversion means connected to the output of said chamber for receiving the mixture of steam and products of combustion and converting partially the energy thereof into mechanical energy; means interconnecting said first conversion means with said sources of compressed air, fuel and water whereby all said sources are operated simultaneously with the operation of said first conversion means; second conversion means connected to said first conversion means for converting into mechanical energy the remaining available energy of said steam and products of combustion from said first conversion means; and valve means between said first and second conversion means, said first and second conversion means being operated when said valve means is in open position, said first and second conversion means being held stationary in inoperative position when said valve is in closed position, said mixture of steam and products of combustion having a substantially constant energy content for a predetermined time interval during which said first and second conversion means are in inoperative position with said valve in closed position, said mixture of steam and products of combustion transferring energy to said first and second conversion means upon return of said valve means to said open position from said closed position.
