    Abstract: The present invention relates to a pump (15) for pumping a coolant (9) within a Dewar vessel (1) and to a corresponding Dewar vessel (1) for storing samples in a coolant (9). The Dewar vessel (1) comprises a thermally insulated reservoir (3) for the coolant (9) and a sample vessel (11) provided separately and arranged in the thermally insulated reservoir (3). The reservoir (3) is connected to the sample vessel (11) in such a way that the level of coolant (9) is constant in the sample vessel (11). Pump (15) may help in keeping the level of coolant (9) in the sample vessel (11) constant. For this purpose the pump (15) comprises a chamber (17) with an inlet (19) and an outlet (21), a closing element (23) and a pressure increasing device (25). Therein, the inlet (19) is connectable to the reservoir (3) and the outlet (21) is connectable to a sample vessel (11) of the Dewar vessel (1). The chamber (17) is adapted to fill with coolant (9) through the inlet (19) by gravity and the closing element (23) is adapted to automatically close the chamber (17) when it is full of coolant (9). The pressure increasing device (25) is adapted to increase the pressure within the chamber (17), after the chamber (17) is closed, until the coolant (9) is released through the outlet (21).

    Abstract translation: 本发明涉及一种用于泵送杜瓦瓶(1)内的冷却剂(9)和用于将样品储存在冷却剂(9)中的相应的杜瓦容器(1)的泵(15)。 杜瓦容器(1)包括用于冷却剂(9)的隔热储存器(3)和分别设置在隔热储存器(3)中的样品容器(11)。 储存器(3)以样品容器(11)中的冷却剂(9)的水平恒定的方式连接到样品容器(11)。 泵(15)可以帮助保持样品容器(11)中的冷却剂(9)的水平恒定。 为此,泵(15)包括具有入口(19)和出口(21),闭合元件(23)和增压装置(25)的腔室(17)。 其中,入口(19)可连接到储存器(3),出口(21)可连接到杜瓦瓶(1)的样品容器(11)。 腔室(17)适于通过重力通过入口(19)填充冷却剂(9),并且关闭元件(23)适于在充满冷却剂(9)时自动关闭腔室(17)。 压力增加装置(25)适于在腔室(17)关闭之后增加腔室(17)内的压力,直到冷却剂(9)通过出口(21)释放。
