    摘要: A fuel injection nozzle of the inwardly opening type has a valve member (16) slidable in a bore (15) in a nozzle body which is secured to a holder (10). The valve member is biased by a first spring (21) into contact with a seating and is movable from the seating by fuel under pressure. An abutment rod (25) is engageable by the valve member after a predetermined movement of the valve member away from the seating. The abutment rod is biased by a second spring (27) housing in an insert (24) mounted in screw thread engagement within a bore in the holder. The rod extends through and is guided by an aperture (24A) in the insert and is further guided by guide means removed from the insert. The guide means can be a bush (23) carried by the holder, the coils of the first spring (21) or the valve member.

    摘要: A fuel injection nozzle for internal combustion engines has a valve member slidable in a bore within a nozzle body. A first bore portion (12) in which a first valve member portion is a close sliding fit extends from an end face (8) of the body (1). The first bore portion (12) is connected by an annular recess (13) in the wall of the bore, forming an undercut bore portion, to a second bore portion (15) which surrounds a reduced diameter portion of the valve member, the end of which seats in the closed condition of the nozzle on a valve seat (18) formed in the nozzle body (1). This prevents the access of fuel from the undercut bore portion (13) via the second bore portion (15) to one or more spray holes (20) formed in a tip portion (5) of the nozzle body. A fuel supply passage (24) extends from the end face of the body within the body wall and intersects an eccentric extension (26) extending from the undercut bore portion (12) for the supply of fuel thereto, the intersection including the portion of the eccentric extension closest to the end face (8).
