AFUEL injector claimed to give complete atomization of the fuel, and to possess a long working life, is disclosed in patent No. 701,104. The patentee is Tsurukichi Ono, Japan. According to this inventor, the conventional injector having a springloaded needle-valve is subjected to slight sideways forces, caused probably by the end of the spring. This means that the valve does not descend concentrically, and a slight defacement of the seating is thereby caused. The object of the invention is to prevent the B24
transmission of side loads to . the needle-valve.
As shown in the drawing, the needle-valve (I) is hollow and contains a push-rod (2) to which the spring force is applied. The push-rod makes contact with the valve via some simple form of universal joint, such as a sharp centrepoint or a ball (3) as shown. The push-rod is made an easy fit in the valve so that it cannot touch the sides, and a suitable indentation is made to locate the ball.
