ABSTRACT:
An apparatus for delivery of melting rings and valves to an inductor heater, for hard facing of valves for internal combustion engines by melting rings of heat-resistant alloy upon the working surfaces of valves, comprises gravity feed trays, one for feeding the work valves in a vertical position and the other for feeding work rings laid on their side to a tubular body. Between the exit of the tray for feeding the rings and the tubular body there is installed a horizontal tray which is located under the gravity feed tray for feeding the valves and in the same vertical plane with said tray. The distance between the sliding surfaces of the tray along which the valve head moves and the sliding surfaces of the horizontal tray along which the ring lying on its side moves is less than the length of the valve stem, so that the valve stem enters the hole of the ring and delivers it to the tubular body. Near the upper end of the tubular body there is installed a stop interacting with the valve stem for positioning the valve falling into the tubular body with its stem being upwardly directed.
