部材。[Claims for Utility Model Registration] 1. A member for preventing rotation of an adjusting screw, comprising a curved member 1 consisting of two spring legs 2 and 3, wherein one end of the spring legs 2 and 3 is common. A mutually coaxial and congruent threaded hole 8, 9 is formed in each spring leg 2, 3 for the reception of an adjusting screw 7 which is installed at right angles to the socket 4 of the spring leg and which is to be prevented from rotating. In one version, at least one transverse strut 5 is arranged between the two spring legs 2, 3, which limits the possible spring displacement of the two spring legs 2, 3 relative to each other to a predetermined spacing S; Threaded holes 8, 9 are formed in both spring legs 8, 9 with a preload applied to the spring legs 2, 3, so that the adjustment screw 7 can be removed when both spring legs are preloaded.
, 14 and then releasing the spring legs 2, 3, the restoring movement of the spring legs 2, 3 causes the screw holes 8
, 9 and the adjusting screw 7, the rotation preventing member is configured to generate a predetermined amount of frictional force between adjacent surfaces of the adjusting screw 7. 2 A transverse strut 5 is installed on one spring leg 3, the free end of the transverse strut 5 having a predetermined spacing S with respect to the other spring leg 2; 2. The circuit according to claim 1, wherein screw holes 8, 9 are formed in both spring legs 2, 3 in a state in which a preload is applied to the spring legs 2, 3 until they come into contact with the spring legs 2. Motion prevention member. 3 In the unloaded state of the bending member 1, the spring leg 2
is in contact with the horizontal strut 5, and the spring legs 2,
3 . The rotation according to claim 1 , wherein the desired tension state for forming the screw holes 8 , 9 and screwing in the adjusting screw 7 is created by flexing away from each other by a predetermined distance S. Prevention member. 4 The screw holes 8, 9 for receiving the adjusting screw 7 are arranged in the spring legs 2, 3 in such a way that, in the tensioned state of the bending member 1, the adjusting screw 7 is guided into these screw holes 8, 9 with little play. The rotation prevention member according to any one of claims 1 to 3, characterized in that the rotation prevention member is formed as follows. 5 the curved member 1 is coupled to the adjustment lever;
5. Rotation prevention member according to claim 1, characterized in that the adjusting screw (7) cooperates with a stopper. 6. The anti-rotation member according to claim 5, wherein the adjustment lever constitutes an Angleich lever of a governor for a fuel injection pump. 7. Anti-rotation according to claim 1, characterized in that the bending element 1 is fixedly connected to the housing part, and the adjusting screw 7 serves as an adjusting mechanism or an adjustable stop. Element.
