Abstract (en)
[origin: WO2017067930A1] A mobile valve member (48) designed to be arranged in the nozzle body (30) of a fuel (F) injector (10), extends along a main axis (XI) and comprises a piston (50) formed of a male first cylinder (62) of effective diameter (DE) forming the top end of the mobile member (48) and of a second cylinder (64) provided with an internal cylindrical bore (68) of diameter (DE) and a shutoff member (52) comprising a male cylindrical shaft (84) of effective diameter (DE) which is a sliding fit in the internal bore (68), and of a member (88) extending as far as a pointed end provided with a mobile seat (56) and forming the bottom end of the mobile member (48). The mobile member (48) is hydraulically balanced and has a length between its top end and its bottom end that is variable because of the sliding of the cylindrical shaft (84) in the internal bore (68) of the piston.
