摘要:
Improved motor, characterized in that in the combustion chamber of the motor at least one valve "running around" (16) in this chamber is provided for.
摘要:
A cylinder head assembly (2) at least a first rotary valve (5), said valve, • having a substantially spherical body and • comprising o a first opening (31) to the exhaust duct substantially parallel to the valve central axis of rotation, and o a second opening that can be intermittently brought into fluid communication with the combustion chamber, and further comprising • a shaft fixed to the valve and coaxial with the valve central axis of rotation and located opposite the exhaust duct, said shaft being connected to a drive for rotating the valve in correspondance to the operating strokes of the piston in the cylinder.
摘要:
A ceramic composite valve seal for a rotary valve assembly for use in internal combustion engines having rotary intake valves and rotary exhaust valves which have a spherical peripheral surface, the valve seal being of two-piece construction surrounding the intake or exhaust port and having an upper surface designed to contact the peripheral surface of the rotary valve, the two-piece construction defining a channel whereby compressed gases exert additional pressure on the seal enhancing the sealing contact between the seal and the valve.
