Fuel injector.

摘要

A fuel injector has a circular plate like valve member (31) which is urged into engagement with an annular seating element (29) which is formed on the face of a seat member (23). A discharge orifice (28) is formed in the seat member and through which fuel can flow when the valve member is lifted from the seating element (29) by magnetic forces. The valve member is located within an annular spacer member (22) and formed in the face of the valve member (31) remote from the seating element is a recess (35) in which is located one end of a coiled compression spring (33). The base wall of the recess is inclined at an angle between 6 DEG and 16 DEG and is engaged by the spring so that a lateral force is applied to the valve member to urge it into engagement with the inner wall of the spacer member (22). <IMAGE>
