Abstract
An oil-pneumatic control device for electric appliances, such as a circuit breaker that can be operated between two fixed positions, a device comprising a double-acting piston jack that carries the moving contact of the circuit breaker, each of the piston faces normally communicating with a oleo-pneumatic accumulator through a main valve and this communication can be temporarily interrupted by the actuation of a pilot valve, which brings the face of the piston and the main valve into communication with the reservoir, characterized by the fact that a resistance decompressor hydraulics incorporated into the device, is branched on the outlet side, forming an intermediate conduit that puts the two main valves in communication.
