Abstract (en)
Upper and lower valve bodies (3,4) are seated together and held in place by the retainer (6) of a valve housing (2). An axially sealed leakage fuel area (22) is defined between the juncture of the valve bodies and the valve housing. A leakage fuel channel (26) of reduced cross sectional area is defined between the wall surface (24) of the lower valve body (4) and the retainer. The channel is preferably formed by laser processing or by chemical or mechanical polishing.
