A circuit breaker including a stationary frame, at least a pair of arc contacts, an actuation rod, a compression chamber in which a portion of the dielectric gas is compressed; a cylinder and a piston connected with the rod, which are movable within the stationary frame along main axis, for compressing the portion of the dielectric gas in the compression chamber; a link mechanism connecting the piston to the rod, wherein the stationary frame includes a cylindrical portion with which each of the piston and of the cylinder are radially in gastight contact and which bounds the compression chamber together with the piston and the cylinder.

To improve cooling performances of quenching gas in a gas blast switch comprising a gas channel connecting an arcing region to a gas storage chamber delimited by radially opposite inner and outer walls and axially opposite first and second end walls, a flow guiding radial wall extends in the gas storage chamber spaced from each wall delimiting the chamber, an opening of the gas channel into the gas storage chamber through the first end wall faces a space between the flow guiding radial wall and the inner wall, the outer wall includes a deflecting portion protruding in the gas storage chamber and facing the second end wall, and at least part of the deflecting portion is offset from the flow guiding radial wall in an axial direction oriented from the gas channel towards the gas storage chamber.
