Trail run, to ensure operation flexible of nozzle and each sealed face without leakage Auto-shut nozzle Auto-shut nozzle is developed from general nozzle, which has function of automatic switch off. As container is full, nozzle valve is closed automatically, keeping clean and safety of operation environment. Due to this merit, this kind of nozzle is widely adopted in many brands of fuel dispensers. This handbook will introduce the structure and working principle of general nozzle. Structure Illustrated in Diagram 2-31, auto-shut nozzle consists of nozzle body, main valve, top level, switch membrane, auto-shut level, side valve core, spout, etc. 1-Nozzle body 2-Cap 3-Ejection pin 4-O-ring 5-Spring 6-Pressure plate 7-Main valve 8-Upper cover 9-Swtich membrane 10-autoshut bar 11-Steel ball 12-Assistant valve 13-Sleeve 14-Air inlet spout 15-Air inlet pipe 16-Spring 17-Spout 18-O-ri fuel dispenser ng 19-Spring 20-Assistant valve core 21-Autocontrol bar 22-Supporting plate 23-Location-limited plate 24-Switch handle Diagram 2-31: Auto-shut nozzle Main structure of auto-shut nozzle as followed: Four holes in the circle of side valve, which are connected with the upper chamber of switch membrane via the gradient hole on nozzle body; the lower chamber of switch membrane connect to outside via the clearance between nozzle body and auto-shut level. There are three steel balls installed in holes of upper of auto-shut, lift switch handle, auto-shut level is stuck in by there balls; once auto-shut level move upward, main valve will be closed as switch lost supportive point. Metal sheet is installed on switch handle, which is controlled three different positions corresponding to three kinds of openness--- three kinds of flow rate.
