Abstract
Improvements introduced in the object of the main patent No. 289,374, granted on October 21, 1963, by improvements in pneumatic circuit breakers, consisting of an automatic blow valve for said compressed gas circuit breakers located in the path of evacuation of gases below of the cut-off point, which operates by depression inside the contact tube, characterized by the fact that the transmission of the command to the control device, such as a slide, of the automatic blow-off valve, is effected by a path which passes through the valve itself, the path corresponding to the transmission of the order between the valve and its control device corresponds and the relative arrangement of these two organs being such that the trajectory of the order is minimal and avoids changes of direction.
