Abstract:
A method of inducting and compressing a gaseous medium, comprising:providing a closed elongate chamber having a first end and a second end and permiting gaeous fluid flow between the ends, and having an inlet valve selectively operable to admit a fuel/air gaseous medium adjacent the first end of the chamber and an outlet valve adjacent the second end of the chamber;performing induction by opening the inlet and outlet valves while admitting to the chamber a flow of a gas dissimilar to the fuel/air medium and operative to exit the chamber while reducing pressure within the chamber, whereby the reduction in pressure inducts the fuel/air medium through the open inlet valve into the chamber;closing the inlet and outlet valves after an amount of the fuel/air medium enters the chamber;performing compression of the inducted medium by continuing the inflow of the dissimilar gas at a pressure greater than the pressure of the fuel/air medium in the chamber, so that the inflow of dissimilar gas into the chamber compresses the fuel/air mixture, thereby performing the function of a piston within the chamber;detonating the fuel/air mixture in the chamber; and thenopening the outlet valve to allow expanding gas from the detonation to exit the chamber for performing work.
