Abstract
The invention relates to a safety valve comprising a valve body with a guide bore which defines a longitudinal axis, a first opening which is formed on a base of the guide bore, and a second opening which is formed at a distance to the base along the longitudinal axis and which extends along a radial direction extending transversely to the longitudinal axis; a valve needle which is movably mounted in the guide bore of the valve body in an axial direction and which comprises a seal surface facing the first opening; a compression spring device with a spring that is compressed by a deflection and thereby biases the valve needle along the longitudinal axis into a seal position, in which the seal surface of the valve needle seals the first opening; and a thermally activatable trigger unit which has an extension along the longitudinal axis, said extension being greater than the deflection, and which is designed to collapse when a trigger temperature is reached, wherein the compression spring device is supported against the trigger unit.
