摘要： A flame-retardant pressure equalizing valve contains a valve body (3) that is guided in a housing (1). Under the influence of excess pressure, the valve body (3) is displaceable from a closing position into a blow-off position. The housing (1) and the valve body (3) form a first closure (8) and, in series therewith, a second closure (9). The surface of the second closure (9) projected in the opening direction (7) is larger than the surface of the first closure (8) projected in the opening direction (7) and the first closure (8) opens during opening before the second closure (9), so that, during opening, the excess pressure acts on an enlarged surface and the valve is opened promptly. The second closure (9) is spaced from the first closure (8) in opening direction (7). As a result, a better closing behavior and an increased outlet velocity of the outflowing gas are obtained.

摘要： The present invention relates to a device for equalization of pressure between the interior of cooling apparatus and, in particular, deep-freezing apparatus, and the ambient. It proved useful that the same through hole (2) provided in the bottom (1) of a cooling or deep-freezing apparatus is used both for equalizing the pressure and for draining the water. In the through hole (2) there is arranged a vertically movable plug (3) formed so as to tightly rest with its intermediate portion (11) against the respective intermediate portion (8) of the through hole (2). A shift of the plug (3) is limited by means of a stick like protrusion (5') provided on the cover (5) of the through hole (2) and projecting in the same.
