Fuel injection inlet metering valve
An inlet metering valve 16 of a fuel injection equipment 10 comprises a body 18, a first solenoid 30, urging a valve member 24 toward a first extreme position P1, and a first spring 44, which is compressed by the force generated by the coil 32 and magnet 38. A second spring 50 biases the valve membe...

| description | An inlet metering valve 16 of a fuel injection equipment 10 comprises a body 18, a first solenoid 30, urging a valve member 24 toward a first extreme position P1, and a first spring 44, which is compressed by the force generated by the coil 32 and magnet 38. A second spring 50 biases the valve member toward the first position. When under the sole influences of both springs the valve member rests in a neutral position. A second solenoid 34 may be present which urges the valve towards a second extreme position P2. One extreme position allows fuel to flow, while the other closes the valve and prevents flow. The configuration of the valve allows the valve to rest at a typically used position without the need to energies the solenoids and so reduce energy and minimise CO2 emissions. A high pressure pump comprising the inlet metering device is also disclosed. |
