Fuel pressure booster and regulator |
摘要 |
A fuel injection system for an internal combustion engine employs a relatively low pressure pump to provide fuel to injectors located at the engine cylinders. A booster device for maintaining the fluid pressure constant, at a substantially higher level, is connected in series with the line between the pump and the injector and includes one way valves at its inlet and outlet. The booster employs a chamber connected to the fuel line and pressurized by a piston which acts to contract the chamber volume under the force of the coil spring. The piston is cocked against the spring at regular intervals to renew the original volume of the chamber by an arm driven from the engine crankshaft. Sealed volume converters having flexible diaphragm walls are disposed adjacent to the inlet and outlet of the booster device and in the fluid conduit adjacent the injectors to obviate sharp drops in the fluid pressure in the fuel line when the injectors actuate.
