Electric high-voltage circuit breaker

An electric high-voltage circuit breaker comprising:

• a primary chamber;
• and
• a compression chamber,
• wherein the circuit breaker further comprises:
• a valve configured to control a fluid flow between the primary chamber and the compression chamber, wherein the valve comprises:
• a valve body,
• a first valve plate that is arranged axially movable with respect to the valve body, and
• a second valve plate that is arranged between and movable with respect to the valve body and the first valve plate,
• wherein the first valve plate comprises:
• at least one opening enabling the fluid flow through the first valve plate, wherein a first surface of the valve body forms a valve seat for the first valve plate, and wherein a first surface of the first valve plate forms a valve seat for the second valve plate;
• and
• wherein the first valve plate and the second valve plate each comprise a circular ring shape, wherein an outer diameter of the second valve plate is smaller than an outer diameter of the first valve plate.
