Spherical rotary valve having bifurcated apertures

摘要

An improved rotary valve for a spherical rotary valve engine in which the intake spherical valve and the exhaust spherical valve have an aperture on the spherical periphery for communication with the inlet port and exhaust port of the cylinder, respectively, the aperture having longitudinal parallel edges spaced apart a distance equivalent to the diameter of the inlet port or the exhaust port of the cylinder head, the lateral ends of the aperture on the spherical periphery of the intake and exhaust valve being curvilinear and of a semi-circular design, the apertures being bifurcated by a rib member extending between the curvilinear semi-circular lateral end walls of the aperture, the rib members upper surface conforming to the spherical peripheral arcuate shape of the rotary valve.

1. An improved spherical rotary intake valve for use in a rotary valve internal combustion engine for cooperation with the inlet port of a cylinder of said internal combustion engine for the introduction of a fuel/air mixture into said cylinder, said improved spherical rotary valve having a drum body of spherical section formed by two parallel planar side walls of a sphere disposed about a center thereof, thereby defining a spherical shaped peripheral end wall and formed with a shaft receiving aperture between said planar side walls, said drum body formed with a donut-shaped cavity in one said side wall thereof and at least one aperture formed in said spherical peripheral shaped end wall in communication with said donut-shaped cavity, said aperture formed in said spherical peripheral shaped end wall having longitudinally disposed side walls substantially parallel to said planar side walls of said drum body, said end walls of said aperture formed with a spherical shaped end wall comprised of opposing curvilinear semi-circular shapes, the radius thereof equaling the radius of an inlet port of said cylinder, said improvement comprising:
a bifurcating rib extending between said opposing curvilinear semi-circular shaped end walls, said bifurcating rib contacting a valve seal surrounding said inlet port of said cylinder during rotation of said spherical rotary intake valve.
