    • A fuel injector valve (1) of a piston engine, which comprises a fuel chamber (3) for the fuel to be injected, a valve needle (9) for guiding the fuel injection from the fuel chamber (3) into the cylinder (4) of the engine, a spring (10) for pressing the valve needle (9) towards the closed position, and a piezoelectric actuator (11) for guiding the valve needle (9). Additionally, the injector valve (1) comprises a drawbar (22), which is loosely coupled to the valve needle (9), a second drawbar (23), which is attached to the piezoelectric actuator (11) and loosely coupled to the drawbar (22), and that the injector valve (1) comprises a second spring (24) fitted in connection with the drawbar (22) for pressing the valve needle (9) towards the closed position and a third spring (25) fitted in connection with the second drawbar (23) for pressing the valve needle (9) towards the closed position.
    • 一种活塞式发动机的燃料喷射阀(1),其包括用于待喷射燃料的燃料室(3),用于将燃料喷射从燃料室(3)引导到气缸(4)中的阀针 ),用于将阀针(9)压向关闭位置的弹簧(10)和用于引导阀针(9)的压电致动器(11)。 另外,喷射器阀(1)包括松动地联接到阀针(9)的牵引杆(22),第二牵引杆(23),其连接到压电致动器(11)并松动地联接到牵引杆 (22),并且所述喷射器阀(1)包括与所述牵引杆(22)连接的用于将所述阀针(9)压向所述关闭位置的第二弹簧(24)和安装在所述闭合位置的第三弹簧(25) 其中第二牵引杆(23)用于将阀针(9)压向关闭位置。
