Abstract:
A pressure relief valve for pressure equalization between an essentially closed space and the surrounding atmosphere is disclosed. The pressure relief valve includes a valve housing with:—a wall defining a flow passage with an upwardly oriented outflow,—a valve body arranged to cooperate with a valve seat arranged in the outflow,—a stem configured for axial guidance of the valve body,—a damper arranged to dampen axial movement of the stem, wherein the damper is configured such that force curves of compression and expansion respectively diverge due to hysteresis loss or pronounced hysteresis loss.
