Abstract: A rotary valve is disclosed suitable for replacement of poppet valves. The valve is temperature controlled through a combination of heat transfer techniques and means for reducing heat transfer between gas flows and the valve components. Assymetric geometry is used in the seals to reduce wear and friction, and a removable combustion chamber in the valve housing is used to facilitate fabrication, servicing and performances. A prototype of the valve was developed for a 30 cubic inch displacement four-stroke spark-ignition engine. The gas seals and lubricated parts of the rotary valve have been found to remain below 400 degrees Fahrenheit during test runs wherein the valve controlled gas flows and has maintained a brake mean effective pressure of 108 to 121 psi for periods of up to an hour. The valve uses pure rotation, and can be dynamically balanced for operation to the peak RPM permissible with reciprocating pistons. A four-stroke engine converted to rotary valving needs very few parts. For example, a four cylinder automotive engine fitted with a spheroidal rotary valve system requires only 11 moving parts; namely a crankshaft, pistons and rods, the valveshaft and a timing belt to drive the valveshaft. The valve is applicable to new engine production and is also suitable as a cylinder head assembly for retro-fit to existing engines of the overhead camshaft type.

Abstract: A variable valve timing mechanism for an internal combustion engine comprising at least one rotary valve (1) having at least two ports terminating as openings (2, 3) in its periphery, a cylinder head (7) having a bore in which the rotary valve (1) rotates, and a window (6) in the bore communicating with a combustion chamber (8). The openings (2, 3) successively align with the window (6) by virtue of the rotation. The mechanism also comprises a drive mechanism (13) driving the rotary valve (1). The at least two ports (2, 3) of the rotary valve (1) are an inlet port and an exhaust port. The drive mechanism (13) varies the angular velocity of the rotary valve (1) at least within a portion of at least one engine cycle whilst maintaining an average angular velocity over the at least one engine cycle that has a fixed relation to the average angular velocity of crankshaft over the at least one cycle.

Abstract: An internal combustion engine (10) incorporating a rotary intake-exhaust valve (30). Intake exhaust valve (30) rotates between intake passage (36) and exhaust passage (34) such that intake-exhaust port (28) is aligned with intake passage (34) during the intake cycle and aligned with exhaust passage (34) during the exhaust cycle. Use of a rotary valve eliminates vibration normally found when reciprocating intake valve and exhaust valve are used and also provides weight saving due to simplified manufacturing processes, fewer parts and a higher strength engine wall due to elimination of one opening port into the engine. Valve (30) is operated by electro-mechanical means (40) so that the point in the power cycle at which air is admitted and exhausted may be varied. Means (40) may also be used to vary the length of time the exhaust port or intake port is open.

Abstract: A rotary valve system for an internal combustion engine having ball-type valves with through bores. The valves are driven by rocking cam mechanisms within passageways for controlling communication through intake and exhaust passages. Valve seats are arranged to either side of the valves such that sealing thereof may occur. In one embodiment, side cut portions are employed to allow either intake or exhaust gases to flow around the valve body as well as through the through bore when the valve is in the opening or closing orientation. In another embodiment, a through bore of square cross section is provided to increase flow during opening and closing thereof. In a third embodiment, a bias mechanism is employed to provide torque on the valves and drive mechanism to eliminate clearances such that impact between components will be reduced or eliminated.
