Controlled Air Operated Ejector

Ejector 10 includes braze container 15 having nozzle 20 at one end for emitting braze compound in extruded beads. Container 15 is connected by air hose 25 to air supply 35 via solenoid operated valve 30 which is normally closed.

Valve 30 is selectively energized to permit air under pressure to pass from supply 35 to container 15 so that a bead of brazing compound is ejected. The amount ejected depends upon the length of time for which valve 30 is energized.

Valve 30 is energized under control of switch 40 mounted on container 15. Switch 40 is connected in the circuit for the pickup coil of relay R45. With relay R45 picked up, normally open contact R45b is closed so that the hold coil for R45 is energized. This completes a circuit to the solenoid of valve 30 which is then operated to the open position. Air then flows from supply 35 to container 50 to force a bead of braze from it. Valve 30 remains open until capacitor C1 discharges. Manually operated switch MSW can be caused to bypass capacitor C1 to enable the ejection of longer beads of braze from container 15.
