Pressure-Resistant Tank for Cryogenically Stored Fuel

Abstract

A heat-insulated tank is provided for use as a reservoir for an operating agent of a drive assembly of a motor vehicle, particularly a heat-insulated cryotank for condensed gases. The tank consists at least of an interior tank for receiving a condensed gas, which interior tank is held in a heat-insulated manner in at least one exterior tank, which can be closed by a lid. At least one valve, a sensor, and/or a conduit connecting piece with pertaining conduits are accommodated in the insulation space, in the area of the lid between the interior tank and the exterior tank, fixedly connected with the lid.

1 . A heat-insulated tank for use as a reservoir for an operating agent of a drive assembly of a motor vehicle, the heat-insulated tank comprising:
 an interior tank for receiving a condensed gas;   an exterior tank in which the interior tank is arranged in a heat-insulated manner;   a lid operatively configured to close the exterior tank;   at least one of a valve, a sensor, and a conduit connector with an associated conduit, being fixedly connected with the lid;   wherein the at least one of the valve, the sensor, and the conduit connector with the associated conduit are configured so as to be arranged in an insulation space in an area of the lid between the interior tank and the exterior tank.   
     
     
         2 . The heat-insulated tank according to  claim 1 , wherein the tank is a heat-insulated cryotank for the condensed gas. 
     
     
         3 . The heat-insulated tank according to  claim 1 , wherein, viewed in a longitudinal tank axis direction, the exterior tank comprises a circumferential wall with a bottom and an open end opposite the bottom, the open end being closable by the lid. 
     
     
         4 . The heat-insulated tank according to  claim 3 , wherein the heat-insulated tank is a molded tank. 
     
     
         5 . The heat-insulated tank according to  claim 1 , wherein the exterior tank comprises at least one hollow-cylindrical circumferential wall with a removable bottom and a removable lid. 
     
     
         6 . The heat-insulated tank according to  claim 5 , further comprising:
 at least one of an additional valve, an additional sensor, and an additional conduit connector with an associated conduit is fixedly connected with the bottom, the at least one of the additional valve, the additional sensor, and the additional conduit connector with the associated conduit being arranged in the insulation space in a bottom area between the interior tank and the exterior tank.   
     
     
         7 . The heat-insulated tank according to  claim 6 , wherein the associated conduits extend out of the exterior tank through at least one of the lid and the bottom. 
     
     
         8 . The heat-insulated tank according to  claim 6 , wherein at least one of the associated conduits is integrated along a portion of its length in at least one of the lid and the bottom. 
     
     
         9 . The heat-insulated tank according to  claim 6 , wherein at least one of the valve, the additional valve, the sensor, and the additional sensor is integrated partially in at least one of the lid and the bottom. 
     
     
         10 . The heat-insulated tank according to  claim 9 , wherein the at least one valve and the additional valve integrated in at least one of the lid and the bottom provides a valve seat constructed in the at least one of the lid and the bottom. 
     
     
         11 . The heat-insulated tank according to  claim 3 , wherein the lid is a metal lid connected to the circumferential wall. 
     
     
         12 . The heat-insulated tank according to  claim 11 , wherein the lid is vacuum tight screwed to the circumferential wall to form the connection.
