Abstract

After a combustion chamber is filled with a combustion mixture of gases, channels extending upward from the valves for admitting the gas components of the mixture to a gas inlet bore are flooded with a quantity of water injected through an additional valve by a hydraulically driven piston. After the hydraulic pressure behind the piston is turned off, the water chamber in front of the piston is refilled by the inflow of water at water line pressure, which is not sufficiently high enough in pressure to reopen the water outlet valve until the piston is again driven.
