摘要： A fuel supply apparatus includes a movable unit, a coil, a drive circuit portion, and a drive control portion. The drive circuit portion energizes the coil with a drive electric current of a first value such that the movable unit is displaced from an opening-side position to a closing-side position. The drive circuit portion energizes the coil with the drive electric current of a second value that is smaller than the first value such that the movable unit is held at the closing-side position. The drive control portion controls the drive circuit portion to change the drive electric current from the first value to the second value while the movable unit is being displaced toward the closing-side position based on energization of the coil with the drive electric current of the first value.

摘要： A housing has a compression chamber and a first passage, through which the compression chamber communicates with an accumulation chamber. A discharge valve is provided in the first passage and configured to open to supply fuel from the compression chamber to the accumulation chamber in response to increase in pressure in the compression chamber. A second passage is configured to communicate the accumulation chamber with the compression chamber via the discharge valve. A valve element allows fuel flow from the accumulation chamber to the compression chamber. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. The sidewall of the valve element and the inner wall defining the second passage therebetween define a throttle midway through the second passage for restricting fuel flow from the accumulation chamber to the compression chamber.
