Abstract
A gasoline fuel injector wherein the valve member is in the form of a plate which is attracted towards a pair of pole faces when a winding is energized and the extent of movement of the valve member is limited by a non-magnetic spacer member which is of annular form. In order to reduce the possibility of the valve member sticking to the spacer member the contact area between the valve member and spacer member is minimized by the provision of radially inwardly extending circumferentially spaced tongues engageable by the valve member in the open position.
