VALVE MECHANISM FOR INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Patented Nov. 28, 1916.
Application filed August 24, 1915. Serial No. 47,072.
To all whom it may concern:
Be it known that I, HUGO G. WELL, a subject of the Emperor of Germany, and a resident of the city of New York,, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Valve Mechanism for Internal-Combustion Engines, of which the following is a full, clear, and exact description.
My invention has for its object to provide a valve plate disposed adjacent the head of a cylinder for rotating relatively thereto, there being ports in the valve plate and in the cylinder head for scavenging and cooling the cylinder with air at the period of exhaustion and for supplying air to the combustible mixture in the cylinder. prior to ignition.
Another object of the invention is to provide novel means for rotating the valve plate.
Additional objects of the invention will appear in the following specification in which the preferred form of my invention is disclosed.
In the drawings similar reference charactors refer to similar parts in all the views in which Figure 1 is a sectional view of theinvention; Fig. 2 is a plan view of Fig. 1; Fig. 3 is a diagrammatic view illustrating the positions of the ports in the valve plate at the suction stroke; Fig. 4 is a diagrammatic view illustrating the positions of the ports in the valve plate at the compression period; Fig. 5 is a diagrammatic view illustrating the positions of the ports in the valve plate during the power stroke; and Fig. 6 is a diagrammatic view illustrating the positions of the ports in the valve plate during the exhaust.
By referring to the drawings it will be seen that the engine is provided with a cylinder 10 having a head. 11, there being an annular guideway 12 in the cylinder 10 at the head 11, a valve plate 13 being-disposed within the cylinder 10 and against the head, the periphery 14.- of the valve plate being disposed in the annular guideway 12 In the cylinder head 11 there is an exhaust port 15, a combustible mixture port 16 and an air inlet port 17, these ports 15, 16 and 17 has two combustible mixture ports 18, two
exhaust ports 19 and two air inlet ports 20, there being also two auxiliary air inlet ports 21.
- As will be seen by referring to the diagrammatic views 3, 4, 5 and 6, the combustible mixture port 16 and the cylinder head 11 is uncovered by a port 18 in the valve plate .13 during the suction stroke, the port 18 in the valve plate 13 passing the said combustible mixture port 16 in the cylinder head at the end of the suction stroke so that the ports 15, 16 and 17 in the head 11 will be closed by the valve plate .13 on the return or the compression stroke of the piston, the said ports remaining closed as illustrated in Fig. 5 during the power stroke. But, on the exhaust stroke, one of the ports 19 in the valve plate 13 communicates with the exhaust port 15 in the cylinder head 11 and one of the ports 20 in the valve plate 13 communicates with the air inlet port 17 in the cylinder head 11, so that the air, which has been compressed in the crank case 22 will be forced through the pipe 23 into the cylinder to cleanse and cool the cylinder, the said air with the gases of combustion passing through a port 19 in the valve plate and out of the exhaust 15 in the cylinder head. on the completion of the exhaust stroke and on the commencement of the suction stroke of the piston, one of the ports 18 in the valve plate 13 will uncover the combustible mixture port 16 so that a new charge may be drawn into the cylinder.
As a means of enriching the combustible mixture I provide the auxiliary air ports 21 which serve to supply the combustible mixture in the cylinder with a charge of air immediately preceding the'power strokes in the cylinder head 11 there is a. bearing 21 in which a stud 25 is journaled, this stud a crank 33 on the crank shaft 30 by means of a piston rod 34.
It will be understood that with the arrangement of the ports in the valve plate 13, illustrated and described above, the valve plate 13 will be rotated one-eighth of a complete revolution With each stroke of the piston; that is, the valve .plate 13 will make one-half-a revolution With a complete cycle of the engine. I
Having thus described my invention I claim as new and desire to secure by Letters Patent 1. In a valve mechanism for internal combustion engines, a cylinder having a head, with a combustible mixture port, an exhaust port, and an airport, a valve plate for rotatng against the head for con'unanding the three ports, and means for operating the rotary valve for uncovering the cylinder air and exhaust ports simultaneously.
In a valve mechanism for internal combustion engines, a cylinder having a head with a combustible mixture port, an exhaust port and an air port, a valve plate for rotating against'the head and having a port for uncovering the combustible mixture port in the cylinder head during the suction period of the engine, a ert for uncovering the exhaust port in the cylinder head during the exhaust period of the engine, and an other port for uncovering the air port in the cylinder duringthe compression period in the engine.
3. In a valve mechanism for an, internal combustion engine, a cylinder having a head with a combustible mixture port, an exhaust port and an air port, 'a plate valve for-rotating against the head and having a port for uncovering the combustible mixture port during the suction period of the engine, and ports for uncovering the exhaust port and the airport in the cylinder head during the exhaust period of the engine.
bastion engines, a cylinder having a head. with acombustible mixture port, an exhaust port and an air port, a valve plate for rotating against the head, and having a port for micovering the combustible mixture port in the head during the suction period of the engine, ports for uncovering the exhaust pert and the air port in the cylinder during the exhaust period of the engine, and another port for uncovering the air pcrt during the compression period of the engine.
In. testimony whereof I have signed my name to this specification in the presence of the two subscribing Witnesses.
Y HUGO C. WELL.
