Fuel injection valve for IC engine fuel injection system has fuel feed with connection point and pipe extending to foot of actuator for movement of valve closure relative to valve seat surface

摘要

The fuel injection valve (1) has an electrically-controlled piezoelectric or magnetostrictive actuator (4) for movement of a valve closure (29) within a valve housing (2) relative to a valve seat surface (30). The valve housing has a fuel feed (17) with a connection point (21) and a pipe (18) enclosed by a plastics sheathing (22), extending to the actuator foot (7) of the actuator.
