Patent ID: 7918208

Claim:
A fuel supply apparatus for a vehicle, the fuel supply apparatus comprising: a fuel portion for receiving fuel; a valve element located in a fuel passage, which communicates with the fuel portion; a delivery portion for supplying fuel pressurized in a compression chamber, which is located downstream of the fuel passage; a movable portion movable between a closed position and an opened position and configured to make contact with the valve element; a coil portion for applying magnetic attractive force to the movable portion; a drive circuit portion configured to manipulate the movable portion from the opened position to the closed position by supplying a first driving current to the coil portion; the drive circuit portion being configured to maintain the movable portion at the closed position by supplying a second driving current, which is less than the first driving current, to the coil portion; drive control means for controlling the drive circuit portion by switching supply of the second driving current to supply of the first driving current to move the movable portion to the closed position in the course of movement of the movable portion to the closed position by supplying the second driving current; and fuel-pressure detection means for detecting pressure of fuel supplied from the delivery portion, wherein the drive control means is configured to determine a start point, at which supply of the second driving current is started, based on the pressure of fuel, and wherein the drive control means is configured to perform a learning processing to gradually increase a switch period, which is from the start point to a switch point at which supply of the second driving current is switched to supply of the first driving current.
