Zusammenfassung:	PCT No. PCT/DK90/00050 Sec. 371 Date Jul. 25, 1990 Sec. 102(e) Date Jul. 25, 1990 PCT Filed Feb. 21, 1990 PCT Pub. No. WO90/10168 PCT Pub. Date Sep. 7, 1990.A pressure relief valve for pressure equalization between a closed space and the surrounding atmosphere comprises a valve housing (1) with an upwardly facing blow-off opening (11) in which a conical valve seat (13) is formed. A drop-shaped body (14) arranged in the blow-off opening (11) is formed on its underside with a conical valve surface (15) co-operating with the valve seat (13). The drop-shaped body is connected with a lifting disc (21) which has a larger area than the valve seat (13) and is surrounded by a free passage slot (22). By suitable dimensioning, advantageous characteristics can be obtained for pressure and blow-off velocity as functions of the blow-off quantity, and the blow-off will always take place in the form of a jet which by means of the drop-shaped body (14) is directed vertically upwards at high velocity.
