Title:
PLUNGER PUMP DRIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2003/033902
Kind Code:
A1
Abstract:
Control means (100) controls, according to the voltage fed from a battery (6), the pulse application to a magnet coil (24) of a plunger pump (20) that is reciprocated by the magnetic driving force produced by the pulse application to the magnet coil (24) and sucks and pressure−delivers the fuel. If the voltage of the battery (6) is low, the pulse application time of the magnet coil (24) is increased&semi contrarily if the voltage is high, the pulse application time is decreased. Thus, irrespective of the voltage of the battery (6), stable delivery performance and power consumption reduction can be achieved. In driving a plunger pump, irrespective of the fluctuation of the power supply voltage, stable delivery performance is ensured, and the power consumption is reduced.
