Description: |
| Abstract:
Our invention relates to explosive engines of the two cycle type, and has in view the provision in such an engine of a positive sliding sleeve valve which shall accurately control the opening and closing of the exhaust and intake ports. As is well known in a two cycle engine, it is necessary for the exhaust and charging ports to be opened almost or quite simultaneously, the explosion gases passing from the cylinder through the exhaust ports at the time that the explosive mixture is being forced in through the charging ports. It is the object of our invention to provide a valve member which shall be in effect a sleeve surrounding and outside of the explosion cylinder and which shall perform in properly timed sequence the operations of connecting the crank chamber with the carburetor or fuel supply at the proper moment, thereafter opening the exhaust and admission ports for the required time, then closing said ports and opening ports for the admission of air to pass around outside of the valve sleeve and through the exhaust chambers outside of the cylinder. It is a further object of our invention to so construct the aforesaid sleeve valve member that the cool explosive mixture from the carburetor will he compelled to pass through a passageway formed in the valve sleeve entirely around the same adjacent that part of the sleeve which comes next to the hot exhaust flame. It is a further object of our invention to provide a double or compound piston and cylinder in combination with the aforesaid sleeve valve such that air will be forced around through the exhaust chamber about the cylinder when the exhaust ports are closed.
Claim:
An explosive engine comprising a cylinder provided with a series of exhaust ports circumferentially disposed in a given plane around the cylinder, and a correspondingly positioned series of admission ports circumferentially disposed in a different plane spaced from the plane of the exhaust ports, both series of ports being controlled by the piston, a unitary cylindrical member surrounding said cylinder, and means to move the member endwise to open and close the ports. |
