Injection valve with variable flow gap, has valve needle stimulated by actuator element(s) to oscillate in at least one spatial direction to control flow gap geometry and pattern of valve jet

摘要

The device has a variable flow gap, a valve housing in which a valve needle (1) is movable to open and close a flow channel formed by the valve housing and valve needle. The valve needle is stimulated by at least one actuator element so that the valve needle carries out an oscillating motion in at least one spatial direction to control the geometry of the flow gap and the pattern (S) of the valve jet.
