Thermally activatable pressure relief device

A thermally activatable pressure relief device, comprising:

• a housing having opposed first and second ends along a longitudinal axis, at least one inlet passage and at least one outlet passage, wherein the outlet passage is disposed at the first end of the housing;
• a receiving cavity in the housing, which connects the inlet passage and the outlet passage and in which a blocking element is received, the blocking element being movable along the longitudinal axis between a blocking position and a release position, wherein the blocking element blocks a fluid flow from the inlet passage to the outlet passage in the blocking position and releases the fluid flow in the release position;
• an intermediate element disposed between the blocking element and the second end of the housing;
• a support member disposed between the intermediate element and the second end of the housing, wherein the support member holds the blocking element in the blocking position, and wherein the inlet passage opens transversely to a direction of movement of the blocking element from the blocking position to the release position;
• and
• a preloaded compression spring surrounding the intermediate element and configured to urge the blocking element in the direction of movement.
