1. Einrichtung zur Förderung kryogener Flüssigkeiten, dadurch gekennzeichnet, daß eine Membranpumpe (1) über eine Schlauchleitung (2) mit einem in die kryogene Flüssigkeit eintauchenden Pumpenkörper (3) verbunden ist und daß der Pumpenkörper (3) eine durch­ gängige Bohrung (7) mit zwei Hohlräumen (8 und 9) besitzt, in denen sich jeweils eine Ku­ gel (10 bzw. 11), deren Durchmesser größer als die Bohrung (8) ist, frei beweglich befindet und daß der eine Hohlraum (9) einen Anschluß (13) zur Membranpumpe (1) und eine An­ saugöffnung (12) und der andere Hohlraum (8) druckseitig einen Anschluß (14) zur Schlauchleitung (5) für die zu fördernde Flüssigkeit besitzt.1. Device for conveying cryogenic liquids, characterized in that a diaphragm pump ( 1 ) via a hose line ( 2 ) with a pump body ( 3 ) immersed in the cryogenic liquid is connected and that the pump body ( 3 ) has a through-going bore ( 7 ) with two cavities ( 8 and 9 ), in each of which a Ku gel ( 10 and 11 ), the diameter of which is larger than the bore ( 8 ), is freely movable and that the one cavity ( 9 ) has a connection ( 13 ) to the diaphragm pump ( 1 ) and a suction opening ( 12 ) and the other cavity ( 8 ) on the pressure side has a connection ( 14 ) to the hose line ( 5 ) for the liquid to be pumped. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Pumpenkörper (3) aus einem saugseitigen Bauteil (3.1), einem Mittelteil (3.2) und einem druckseitigen Bauteil (3.3) besteht und die dem Hohlraum (9) zugekehrten Stirnseiten des Bauteils (3.2) und die dem Hohlraum (8) zugekehrten Stirnseite des Bauteil (3.3) abgeschrägt sind und die Bauteile (3.1, 3.2, 3.3) miteinander verlötet sind.2. Device according to claim 1, characterized in that the pump body ( 3 ) consists of a suction-side component ( 3.1 ), a central part ( 3.2 ) and a pressure-side component ( 3.3 ) and the end faces of the component ( 3.2 ) facing the cavity ( 9 ) ) and the end face of the component ( 3.3 ) facing the cavity ( 8 ) are chamfered and the components ( 3.1 , 3.2 , 3.3 ) are soldered together.
