ressure cover Take out spring and main valve Unload top level and locking nut, pay much attention as replacing 0-ring Adjusting bolt, keeping the clearance between top level and switch handle in the scope of 0.3~~0.5mm Install spring, pressure cover and sealed gasket. 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 structur fuel dispenser e 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-ring 19-Spr fuel dispenser ing 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 n fuel dispenser ozzle 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. The spring on spout is

sirtuins in human cells, some of these molecules are already in clinical trials for safety. Moreover, Dr Sinclair thinks he knows why plant molecules such as resveratrol might affect longevity in animals. Resveratrol is produced when a vine is under stress—for example, due to dehydration or over-exposure to sunshine. According to Dr Sinclair s theory, which he calls xenohormesis, animals rely on such botanical stress signals to give them extra information about their own environments, in the same way that the alarm calls of one species warn others of danger. If bad things are happening to plants, he surmises, that is a reason for pre-emptive animal action. Animal bodies thus react to molecules such as res fuel dispenser veratrol by activating their own defence mechanisms. These, in turn, protect their cells from stress-related damage. Xenohormesis is a variation of a more general theory, hormesis, which interests Suresh Rattan of Aarhus University in Denmark. A good example of hormesis is exercise. In theory, this should damage cells because it increases oxygen uptake, and oxidative stress is bad for things like DNA. Of course, exercise is not actually bad for cell fuel dispenser s—and the reason is that the body activates defence mechanisms which overcompensate for the stress the exercise creates, producing beneficial effects. So, while chronic st fuel dispenser ress is always bad for you, a short period of mild stress followed by a period of recovery can be good. Many of the health benefits of exercise are thought to be due to the synthesis of damage- controlling molecules called heat-shock proteins, and Dr Rattan s group has been experimenting with other ways of triggering these proteins. He has found, for example, that taken in combination with exercise, a spice called curcumin boosts the production of heat-shock proteins several-fold. According to Dr Rattan, such interventions improve the function of a cell over time, and in doing so, may produce clinical benefits such as protection against neurodegenerative diseases.
