Abstract (en)
[origin: EP0375130A2] An inwardly opening fuel injection nozzle has a valve member which is biased into contact with a seating (15) by a spring (30). The force of the spring is transmitted to the valve member by a piston (22) slidable in a cylinder (21) formed in the valve member. A restrictor (27) communicates fuel under pressure from an inlet (26) to act on a surface (20) of the valve member to lift the valve member from the seating to allow the fuel flowing through the restrictor to flow through an outlet orifice (17). The piston (22) is also subject to the pressure downstream of the restrictor and when the pressure attains a predetermined value the piston moves relative to the valve member to uncover a port (28) which by-passes the restrictor to allow unrestricted flow of fuel through the outlet orifice.
