Abstract
An apparatus for surfacing valves by fusing in a high-frequency current field refractory alloy rings applied to the seating surfaces of the valves. The apparatus comprises a tubular body provided with chutes adjoining thereto. The chutes are adapted respectively to feed valves and rings to be fused. After a valve and a ring is assembled under the action of gravity inside the tubular body, the valve with the ring to be fused is delivered by a pusher to a mechanism fixing the valve in a heater. The pusher is mounted for reversible movement in the hozizontal plane.
