e accuracy. Vapor separator mounted check valve should have the anti-backward flow function. Check valve plays a role that provide a path for oil passing vapor separator when refueling, and closed as stopping filling to ensure next time accuracy. Moreover, it is able to reduce hydraulic impact and strict the high pressure in hydraulic system as nozzle suddenly stopping. Here introduce the structure, working principle and troubleshooting of vapor separator generally employed. Structure Diagram 2-12, 2-13 and 2-14 are shown the structural cutaway view, explo fuel dispenser ded drawing and dimensional structure. Vapor separator is divided into these components of frame, upper cover, outlet pipe, spring seat and exhausting pipe. By function, it consists of filter device, vapor segregated device and anti-backward flow device, illustrating in Diagram 2-12 and 2-13. 1\2-Bolt 3-Elastic washer 4-Exhaust jointer 5-Upper cover 6-Valve seat 7-Upper cover gasket 8-Valve bracket 9-Small axis 10-Screw 11-Gas outlet valve unit 12-Fuel return float 13-Ball-float 14-Screw 15-Frame 16-Spring washer 17-Seal gasket 18-Filter unit 19-Bolt 20-Filter 21-Stainer net 22-Gasket 23-Filter end 24-Nut 25-Seal gasket 26-Plug 27-Check valve unit 28-Bolt 29-Gasket 30-Check valve washer 31-Check valve 32-Oil pipe 33-Seal gasket 34-Spring seat 35-Bolt 36-Spring 37-Plug 38-Return oil valve seat 39-Return oil valve 40-Spring 41-Seal gasket 42-Guider bar 43-Oil plug 44-One-way valve Diagram 2-13: Vapor separator exploded drawing Filter device: in past filter material adapts industrial felt, which is difficult to clean and has large flow resistance. Then ladies nylon is used, but this kind of material has low filter precision. Domestic manufacturer now widely adapt stainless steel filter, having advantage of anti-rust, ev fuel dispenser en net holes, guaranteed filter precision and low resistance as well. Diagram 2-12 clearly shows the install position of filter. Pump will be effectively protected through installing a high filter precision strainer at the fuel dispenser

R �I was disappointed to read that Mr Buffett would be leaving the bulk of his entire fortune to the Gates Foundation, with the balance going to foundations controlled by his children. This is the same Mr Buffett who has very publicly advocated the retention of the estate tax to prevent intergenerational transfers of wealth. Current estate-tax rates would ensure that Mr Buffett s estate would generate around $17 billion for the treasury (were he to die this year), which he will now avoid. Is this, perhaps, a classic case of “Do as I say, not as I do� D fuel dispenser avid Zisser San Francisco SIR �I would be the last person to argue against investing research dollars where they can do the most good (“How to spend it� July 1st). But in the case of diabetes the statistics you used underestimate—by multiples—the mortality and disability burden of the diabetes epidemic (350m sufferers by 2025, 80% of them in developing countries). Most of your data is based, originally, on World Health Organisation statistics, which came from death certificates. Rather than coding diabetes as the cause of death, 89% of doctors code the end-stage complications of diabetes. These include heart disease and stroke, renal failure and opportunistic infections. More recent work from the WHO gives diabetes mortality numbers that are 3.5 times higher. The investments that the Gates Foundation and others are directing towards infectious and parasitic diseases like malaria are wonderful and long overdue. Perhaps now they can also address diabetes and cardiovascular disease, which impose an equal burden in the regions they are trying to help.
