Abstract

The valve, which is normally closed, has an axially movable core moved towards a fixed core for opening the valve when the electromagnetic coil is energised. The valve needle is movable axially relative to the closed position upon initial opening movement of the movable core until the latter is within millimetres of the fixed core at which point a stop edge contacts a stop element causing the valve needle to move in conjunction with the movable core. The stop element is pref. provided between two springs respectively biasing the valve needle into the closed position and allowing it to move relative to the movable core and lying within a space for allowing the valve needle to continue moving into the open position after the movable core has reached its end position. The valve ensures a secure seal.
