A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is brought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump flowage formula is showed in Diagram 2-1.

the earliest investors saw a huge return, 350 times or so, on their estimated �?m investment. Few start-ups can hope to become so big so fast. Most new companies wither and die in their first few years, leaving their investors out of pocket. That risk and would-be investors unavoidable lack of knowledge when faced with unproven business plans explain why entrepreneurs struggle to finance their dreams. Not only must entrepreneurs find the money to get a business off the ground, but they will also need further finance if it is to flourish. The search was never easy. But it has become harder in recent years with the opening of what has been called the “equity gap”—a scarcity of ready sources of outside financing for the smallest companies. This matters in an age that has recognised the part new businesses play in invigorating economies. Governments everywhere are desperate to help entrepreneurs start the companies that will create new jobs and new wealth. Which is where the ragtag army of “business angels�?comes in. Professional venture capitalists get all the kudos—and most of the money—but the informal choir of business angels plays a large role in starting the in fuel dispenser novation machine rolling. Between them, the angels form an unofficial and l fuel dispenser ittle-known capital market on which the future is built. The equity gap exists because two well-trawled sources of finance no longer overlap. In their earliest stages, start-up companies typically rely on precarious financing, such as their owners credit cards, second mortgages or cash from close contacts. There is a limit to these sources, which professional venture capitalists disparagingly called the “three Fs”—family, friends and fools. They might provide the first $250,000 or so. But that is too meagre to bring to market the sort of groundbreaking ideas, like Skype, that can eventually turn into a billion-dollar business. So another source of funds is needed. Once, businesses would have turned to venture capitalists, wh fuel dispenser
