C-4250 (G-6298) VALVE ASSEMBLY Abstract of the Disclosure A valve assembly for regulating air flow to an internal combustion engine comprises a valve body having a valve bore forming an induction passage, and a shaft extending across the valve bore. A valve member having a chamfered perpheral edge is secured to the shaft for rotation in excess of 90 degrees between a nonactuating position and a maximum actuating position. A return mechanism urges the valve member toward the nonactuating position when the valve member is rotated away from the nonactuating position. The inner shaft extends through a ball bearing disposed in a shaft socket. A spring washer is disposed between the ball bearing and the socket to resist displacement of the outer race of the ball bearing toward the valve bore. A thrust collar is secured to the end of the inner shaft to resist displacement of the inner race of the ball bearing away from the valve bore.
