Vakuumaflastningsenhed ifølge krav 1, kendetegnet ved, at ventillegemet (40) er indrettet til at blive ført i det væsentlige lineært ind i ventilhuset (20), og at den anden bevægelige part er indrettet til at blive ført lineært ind i ventilhuset (20) modsat denne retning. 3. Vakuumaflastningsenhed ifølge krav 1 eller 2, kendetegnet ved, at ventilhuset (10) omfatter en tredje åbning (26), og at mekanismen (100) omfatter et hus (120) arrangeret i tilknytning til den nævnte åbning (26). 4. Vakuumaflastningsenhed ifølge det foregående krav, kendetegnet ved, at den første bevægelige part (160) er et stempel og at den anden bevægelige part (150) er en stempelstang, der er fast forbundet med stemplet (160), at stemplet (160) og huset (120) danner et aftætnet rum (102) , at stemplet (160) har en overflade, der er indrettet til at kunne påvirkes direkte af det nævnte væsketryk, og at stempelstangen (150) kan fremføres ind i ventilhuset (10) gennem den nævnte åbning (26). 5. Vakuumaflastningsenhed ifølge det foregående krav, kendetegnet ved, at mekanismen tillige omfatter en fjeder (155) indrettet til at tilvejebringe en modstand mod stemplets (160) bevægelse. 6. Vakuumaflastningsenhed ifølge krav 4 eller 5, kendetegnet ved, at huset (120) omfatter en overdækningsplade (130), der er forsynet med åbninger (132), hvorved stemplet (160) kan påvirkes af det nævnte væsketryk, og at overdækningspladen danner an begrænsning for stemplets (160) bevægelse. 1. Vakuumaflastningsenhed ifølge et hvilket som helst af krav 3-6, kendetegnet ved, at den nævnte tredje åbning (26) er dannet i en aftagelig vægdel (110) af ventilhuset (20) .Patent claim 1. Vacuum relief unit for pressure equalization between the ambient atmosphere and a tank in a tanker, the vacuum relief unit comprising: - a valve housing (10) with a first opening (12), with which the valve housing (10) can communicate with the tank, and a second opening ( 24) having a seat (30) for a valve body (40) adapted to be inserted into the valve housing (10) to allow air to flow into the tank, and - a mechanism (100) adapted to able to prevent seawater flow through the valve body (10) in an accident in which the tanker is at least partially submerged in seawater, said mechanism (100) having a first movable member (160) arranged outside the valve body (10), and the movement of which can be controlled by the fluid pressure of the sea water, a second movable part (150) which can be advanced inside the valve housing (10) and which is coupled to the first movable part (160), characterized in that the second movable part A portion (150) is adapted to be brought into abutment against the valve body (40) by a growing movement of the first movable portion (160) to bring the valve body (40) back into abutment against the seat (30). Vacuum relief unit according to claim 1, characterized in that the valve body (40) is arranged to be inserted substantially linearly into the valve housing (20) and the second movable part is arranged to be linearly inserted into the valve housing (20). ) opposite to this direction. Vacuum relief unit according to claim 1 or 2, characterized in that the valve housing (10) comprises a third opening (26) and the mechanism (100) comprises a housing (120) arranged in connection with said opening (26). Vacuum relief unit according to the preceding claim, characterized in that the first movable part (160) is a piston and that the second movable part (150) is a piston rod fixedly connected to the piston (160), that the piston (160) and the housing (120) forms a sealed compartment (102) that the piston (160) has a surface adapted to be directly affected by said fluid pressure and that the piston rod (150) can be introduced into the valve housing (10) through said opening (26). Vacuum relief unit according to the preceding claim, characterized in that the mechanism also comprises a spring (155) adapted to provide a resistance to the movement of the piston (160). Vacuum relief unit according to claim 4 or 5, characterized in that the housing (120) comprises a cover plate (130) provided with openings (132), whereby the piston (160) can be influenced by said liquid pressure and the cover plate forms a restriction on the movement of the piston (160).
