Abstract:
An improved coolant system for an internal combustion engine of the type utilizing a spherical rotary valve assembly wherein said spherical rotary valve assembly comprises a removable two piece cylinder head securable to the internal combustion engine, said two piece removable cylinder head comprising an upper and lower cylinder head section such that when secured to said internal combustion engine define cavities, said cavities for receipt of a plurality of aligned spherical rotary intake valves and a plurality of aligned spherical rotary exhaust valves in communication with a cylinder; said spherical rotary intake and exhaust valves mounted on a rotating shaft means journaled on bearing surfaces within said two piece cylinder head and aligned with said cylinders of said internal combustion engine said improvement comprising:forming said shaft means with a longitudinal throughbore for the passage of coolant therethrough and extending said shaft means exteriorly of said two piece cylinder head at both ends and terminating each end of said shaft means in a coupling member secured to the exterior of said two piece cylinder head, said coupling member defining a reservoir chamber, said reservoir chamber in communication with a conduit in communication with a coolant system to permit the introduction of coolant to said reservoir chamber and into said throughbore of said shaft means at a first end of said shaft means and a conduit in communication with said reservoir chamber of a coupling member at said second end of said shaft means for directing coolant away from said shaft means to said coolant system; said shaft means mounted on a bearing means and having a first sealing means proximate said exterior wall of said two piece cylinder head, said shaft means having second sealing means positioned within said reservoir chamber of said coupling member.
