Abstract (en)
[origin: WO2015052332A1] The invention relates to an injection valve (1), comprising: an injector body (2) having a cut-out (3), a fluid inlet (7), and a fluid outlet (9); a needle body (10), which is arranged such that the needle body (10) can move axially in the cut-out (3) of the injector body (2) and which prevents a fluid flow through an injection opening (12) of the injector body (2) when the needle body (10) is in a closed position and allows said fluid flow otherwise; a control chamber (15), which is arranged in the cut-out (3) and is arranged hydraulically between the fluid inlet (7) and the fluid outlet (9); a control valve (16) having a valve body (17), which is arranged in the control chamber (15) and is configured to prevent a fluid flow between the control chamber (15) and the fluid outlet (9) when the valve body (17) is in a closed position and to allow said fluid flow otherwise; a piezoactuator (20), which is coupled mechanically to the control valve (16) via a first carrier (23), for opening the control valve (16), wherein the piezoactuator (20) can also be coupled mechanically to the needle body (10) to close the injection valve (1).
