    VP500B with power showed in Diagram 4-4. As the simplest d fuel dispenser esign, it could be installed at end of reclaiming pipe, namely, near to tank and inlet. It can simultaneously reclaim 12 nozzles, applicable to fuel dispenser with suction pump or submersible pump. Center-type reclaiming vacuum pump VP500B without power showed in Diagram 4-5. This type of pump is very applicable to city filling station, which is powered by submersible pump, mounted 8 nozzles of reclaiming. The deployment of vapor pipe and air vent of tank ensures station’s normal operation. Distributed reclaiming vacuum pump: each fuel dispenser is mounted vapor reclaiming vacuum pump.

Repeated use breakaway: used for protecting fuel dispenser in case of pull down by vehicle. As exterior pull reaching 310~350lb, breakaway is automatically closed, at same time switch off pipelines of vapor and oil. Coaxial hose: a kind of hose with two layers that delivery vapor in internal and exterior oil. Nozzle: with double-layer pipes, mounted vapor valve. Fuel dispenser with vapor recovery system This kind of fuel dispenser with vapor recovery function is used for reclaiming volatile oil vapor near outlet without affecting normal refueling. There are two types widely adopting in domestic market, one is the new developed fuel dispenser that has vapor recovery function; the other type is improved fuel dispenser based upon traditional dispenser and added vapor recovery function. Generally, these are divided into two categories: submersible type and built-in pump type. Diagram 4-9: Vapor recovery nozzle Submersible fuel dispenser with vapor recovery function If adopt vacuum-aid vapor recovery system, the matching fuel dispenser with vapor recovery function should adopt submersible fuel dispenser. Its working principle is that center vacuum pump g

    because of measures taken only in the past few years. At fuel dispenser the policy level, the government made two huge blunders. The first was to raise the consumption tax in 1997, which wrecked economic confidence. Just as confidence appeared to be recovering in August 2000, the BoJ declared an end to deflation and raised rates. The economy again went into a tailspin and the bank decided to retreat to zero six months later. But with prices falling, the expansionary effect even of a zero rate was lost, since real interest rates remained positive. A radical new measure was tried by the BoJ in effect, printing money by stuffing the accounts that banks hold at the central bank with fre fuel dispenser e cash. That super-loose liquidity, known as “quantitative easing� was withdrawn this spring. Better prospects The current economic expansion, fuel dispenser which began in 2002, will by the end of this year be Japan s longest since the second world war. But not everyone takes its robustness for granted—the BoJ is constantly warned, by politicians especially, not to repeat its mistake of 2000. Richard Jerram, chief economist at Macquarie Research in Tokyo, points out that whereas the BoJ s favoured measure, core consumer prices, shows inflation running at 0.6%, other valid measures show prices still flirting with deflation. Strong uncertainties remain about Japan s potential future rate of growth, while a cushion is needed against external shocks, such as a slowdown in America or a financial crisis in China. In the spring the BoJ published an inflation “range�of 0-2%, within Reuters which it felt comfortable with 1%. But that does not leave much room on the downside, Mr Jerram argues, when even a zero rate loses its effect once prices fall. Others are more optimistic. With inflation now at 0.6%, monetary policy is actually looser despite the rate rise than it was a year ago, when deflation plus the zero rate kept real rates positive. But on July 20th, in its latest survey of Japan, the
