Abstract
An engine valve feed apparatus which feeds engine valves to a valve handling apparatus at a valve pick-up station where the valve handling apparatus picks up and fits the engine valves to an engine cylinder head one after another. The apparatus comprises a valve hanger plate formed with a number of valve holes for tightly receiving a number of engine valves to hang the engine valves upside down. A hanger plate transfer unit transfers a number of the valve hanger plates to the valve pick-up station cone after another. An engine valve thrust-up unit is disposed at the valve pick-up station for thrusting up the valves from the valve hanger plate at the valve pick-up station so as to allow the valve handling apparatus to hold a stem of each of the engine valves. The engine valve thrust-up unit has a holding member movable up and down and formed with a number of positioning holes for receiving the stem ends of the engine valves hung from the valve hanger plate to thereby hold the valves upright when moved up. A stopper prevents the valve hanger plate from being forced up when the stem ends of the engine valves are pushed up from the valve hanger plate.
