ABSTRACT:
A common rail injector for injecting fuel through a high-pressure channel includes a control chamber, a control valve, and a drive unit. The control chamber applies pressure to a nozzle needle. The control valve switches communication of the control chamber between the high-pressure channel and a low-pressure channel. The drive unit selectively sets a valve element of the control valve on a low-pressure side seat or a high-pressure side seat. The drive unit has an actuator and a slide pin member. The slide pin member slides inside a slide hole to transmit a force to the valve element. A diameter of the low-pressure side seat is less than or equal to a diameter of the high-pressure side seat. The pressure in the control chamber is exerted as an assistance force, so that a high-pressure side seat closing load becomes less than or equal to a low-pressure side seat opening load.
