Claim 13

The valve system of claim 4 wherein the intake port and exhaust port of the combustion chamber include at least one compression seal.

Claim 14

The valve system of claim 1 wherein the intake and exhaust shafts are driven by a crankshaft belt driven system.

Claim 15

The valve system of claim 1 wherein the means for lubricating the intake and exhaust shafts include lubrication channels formed around the circumference of the shaft for delivering lubrication to the shafts from an oil source.

Claim 16

A rotary valve shaft indent system for use in internal combustion engines comprising an intake manifold having an exit port; an exhaust manifold having an inlet port; at least one combustion chamber having a piston, an ignition point, an intake port and an exhaust port; a cylinder head; a hollow intake shaft having at least one generally rectangular shaped intake indent element disposed thereon; a hollow exhaust shaft having at least one generally rectangular shaped exhaust indent element disposed thereon; a plurality of lubrication channels disposed about the circumference of the intake and exhaust shafts; and fins disposed at least at one end of the intake and exhaust shafts, said fins extending outwardly along the shafts longitudinal axis for the purpose of drawing ambient air into the shaft for cooling the shafts; wherein the intake and exhaust shafts are securely disposed within a corresponding shaft sleeve and rotatably mounted within the cylinder head between the combustion chamber and the intake and exhaust manifolds by at least one bearing positioned at each end of the shaft sleeve; whereby upon rotation of the intake shaft, the intake indent element allows for intermittent connection of the intake manifold exit port and the combustion chamber intake port, and the unrestricted and direct flow of an air/fuel mixture into the combustion chamber; upon rotation of the exhaust shaft, the exhaust indent element allows for intermittent connection of the combustion chamber exhaust port and the exhaust manifold inlet port, and the unrestricted and direct flow of exhaust from the combustion chamber; and during combustion, the intake and exhaust shafts rotate so as to seal the combustion chamber from the intake and exhaust manifolds.

Claim 17

A rotary valve shaft indent system for use in internal combustion engines comprising an intake manifold having an exit port; an exhaust manifold having an inlet port; at least one combustion chamber having a piston, an ignition point, an intake port and an exhaust port; a cylinder head; a hollow intake shaft having at least one generally rectangular shaped intake indent element disposed thereon; a hollow exhaust shaft having at least one generally rectangular shaped exhaust indent element disposed thereon; a plurality of lubrication channels disposed about the circumference of the intake and exhaust shafts; and fins disposed at least at one end of the intake and exhaust shafts, said fins extending outwardly along the shafts longitudinal axis for the purpose of drawing ambient air into the shaft for cooling the shafts; wherein the intake and exhaust shafts are securely disposed within a corresponding shaft sleeve and rotatably mounted within the cylinder head between the combustion chamber and the intake and exhaust manifolds by at least one bearing positioned at each end of the shaft sleeve; whereby upon rotation of the intake shaft, the intake indent element allows for intermittent connection of the intake manifold exit port and the combustion chamber intake port, and the unrestricted and direct flow of an air/fuel mixture into the combustion chamber; upon rotation of the exhaust shaft, the exhaust indent element allows for intermittent connection of the combustion chamber exhaust port and the exhaust manifold inlet port, and the unrestricted and direct flow of exhaust from the combustion chamber; and during combustion, the intake and exhaust shafts rotate so as to seal the combustion chamber from the intake and exhaust manifolds.

Claim 18

The rotary valve shaft indent system of claim 1 or 15 wherein upon intermittent connection of the intake manifold and the combustion chamber, an air/fuel mixture engages a surface of the intake indent element and pushes the intake shaft in its direction of rotation causing the intake indent to force the air/fuel mixture into the combustion chamber; and upon intermittent connection of the combustion chamber to the exhaust manifold, exhaust gases engage a surface of the exhaust indent element and push the exhaust shaft in its direction of rotation causing the exhaust indent to force the exhaust gases into the exhaust.
