Abstract

Improvement in double-acting, hydraulic actuating devices for electrical appliances, preferably circuit breakers, characterized in that they comprise at least one main impeller for controlling the moving element of the electrical device, and a main pressure accumulator and, furthermore, because the impellers in a certain moment of the filling, they prolong the feeding duration of the main closing or opening valves, beyond the time necessary to ensure their full stroke, eliminating the supply of the intermediate valves after finishing the stroke.
