Abstract
A circuit breaker of the minimum-oil type includes a chamber for quenching the arc drawn between a movable contact rod and a stationary contact as the two separate. To counteract and damp the acceleration effect produced on the movable contact rod within the quenching chamber as a result of gas pressure built up within the chamber due to arc action, a softly elastic annular damping member closely surrounds the movable contact rod and is deformed in a radially inward direction by the gas pressure to press against the movable contact rod and hence provide a braking action for the rod. The radially inward deformation of the elastic damping member is proportional to the gas pressure produced in the quenching chamber and hence provides a braking effect on the movable contact rod which desirably increases with an increase in gas pressure.
