    Abstract: A valve mechanism for a reciprocating piston internal combustion engine having one large poppet valve per cylinder communicating with both inlet and exhaust tracts. A partition between the inlet and exhaust tracts has gas flow ports therethrough moving into and out of alignment with similar gas flow ports in the valve stem. The ports are arranged to permit gas flow from the inlet tract to the outlet tract when the valve is closed.

    Abstract: An intake or exhaust valve assembly for use in a four cycle internal combustion engine including a primary poppet valve, said primary poppet valve having at least one aperture disposed through its valve body and a secondary poppet valve body mounted to seal when engaged to the primary valve body, said secondary valve body having at least one aperture and a biasing means for moving the secondary valve body away from the primary valve body during the initial opening process when the primary valve is accelerating to its opened position. In the closed position of an intake port, the primary valve apertures are not aligned with the secondary valve apertures thus forming a sealed closure across the port. During the opening process of the intake cycle the biasing means moves the secondary valve body away from the primary valve body, thereby permitting intake charge to flow through the apertures disposed in the primary and the secondary valve bodies. In continuation during the final travel of the primary valve to the full opening said secondary valve is unseated by a stop causing the secondary valve to travel in unison to the maximum valve lift position, greatly increasing the volumetric efficiency of the engine.

    Abstract: The intake valve mechanism employs a back-flow valve to prevent undesirable back-flow of gases from a combustion chamber of an internal combustion engine out an intake port of the chamber during a period of time in which a poppet valve for the intake port of the chamber is open. The back-flow valve is positioned between an intake port valve seat and the intake port poppet valve for blocking the intake port in response to pressure in the combustion chamber. To minimize air-fuel resistance through the intake port, a spring is employed for continuously biasing the back-flow valve to track the movement of the poppet valve, the spring having sufficient strength to prevent the back-flow valve from blocking the intake port when the poppet valve is open until the pressure in the combustion chamber reaches a predetermined value.

    Abstract: A new monovalve internal combustion engine of a design specially adapted for screw machine manufacture and including a valve support requiring no lubrication, a combination pull rod and fuel conduit secured to a reciprocating member of a two stage injection pump with the pull rod and both pumps operated by a single compound cam arrangement, a fuel injection nozzle concentric with the valve and with the combustion chamber and having no flexible connections, a fabricated piston rod assembly wherein the crankshaft bearing of the piston rod is greater than the throw of the crankshaft, a fluid seal between the piston and the cylinder against compression losses, a compression chamber which ensures an increasing turbulence of the charge in the cylinder with a maximum at top dead center, and a novel air blower and cleaner system including an arrangement for increasing the volumetric efficiency of the engine and the efficient purging of exhaust gases.
