An automatically resetting safety valve for a generator circuit breaker is to open rapidly and wide, even if the pressure applied to a valve-closing body (,) does not increase substantially over a valve stroke (a) or even falls. In order to ensure this, a valve-closing-body joint (,) of the valve-closing body (,) via a first closing-body lever (H,) and via a first sliding joint (,), is connected in an articulated manner to a first support lever (H,), which is rotatably mounted in a first support lever joint (,) fastened to a lever wall (,). The first sliding joint (,), via a first compression spring (,), is in compressive connection with a spring wall joint (,) fastened to a spring wall (,). The valve-closing body (,) is movable along a plain-bearing axis (A). First and second closing-body levers (H,, H,&prime;) and first and second support levers (H,, H,&prime;), which are arranged in mirror image relative to the plain-bearing axis (A) of the valve-closing body (,), may be provided. Instead of an outer compression spring (,), an inner tension spring (,) may be provided.
