Abstract

The circuit breaker contains a contact system and a blast device. The blast device produces a flow of quenching gas required for the quenching of the switch-off arc in the contact system. The blast device, which is assigned to the contact system, includes an annular piston and a movable cylinder. The piston is sealed via a first sealing ring against the cylinder and via a second sealing ring of different diameter against a movable cylindrical bridging element of the contact system. The circuit breaker also contains a one-way-action valve which is closed in the compression phase and opened in the intake phase. The valve is formed by the two sealing rings which are located in the same plane. They are arranged with axial play in annular grooves which are formed in the piston in flow paths for the quenching gas. Between the sealing rings is arranged at least one spacer element. The rings are supported in a way so that they are movable transversely to the main axis of the piston.
