An actuator arrangement for an electromagnetically operated fuel injector includes a pole member having a first end face and defining an aperture extending from the first end face and an actuator core received within the aperture. The actuator core carries at least one contact member having a contact face that is exposed through the aperture. An encapsulating member is received within the aperture and surrounds the at least one contact member. The first end face of the pole member, the contact face and the encapsulating member are arranged to provide the actuator arrangement with a substantially planar surface for mating with an adjacent component, in use.

Actuator arrangement for an electromagnetically operated fuel injector and method for constructing

A fuel injection apparatus for an internal combustion engine includes a fuel supply passage and a valve arrangement for controlling fuel pressure within the fuel supply passage. The valve arrangement includes a valve member movable between an open position in which the fuel supply passage communicates with a low pressure fuel drain and a closed position in which communication between the fuel supply passage and the low pressure fuel drain is prevented. The valve arrangement comprises damping means for controlling and/or damping movement of the valve member between the closed and open positions.
