Apparatus with blocking device for a sprung lock with a spring mechanism

摘要

The mechanism for blocking further operation of a device after a specified number of relative rotations of the parts (1, 2) of this device incorporates a bent leaf spring (7b). This spring is brought into a blocking position by an element (8b) displaced by a rotation counting unit of the device. An Independent claim is also included for an application of the proposed mechanism in high-pressure pharmaceutical atomizers and injection syringes without needles.
