Abstract: The invention relates to a method for producing a container for a temperature-sensitive operating material of a vehicle, said container having a cylindrical casing and a calotte at both ends with a cylindrical edge part, wherein a) the calotte is inserted with the convex side thereof facing inwards into the casing which is filled with a temperature-sensitive operating material and which is open on at least one side; b) the cylindrical edge part of the calotte and the part of the casing sitting thereagainst are clamped between an outer and an inner retaining block so that the retaining blocks are connected to the calotte and to the casing in a heat-conducting manner; and c) the cylindrical edge part of the calotte is welded to the part of the casing sitting thereagainst by means of a weld seam. The invention further relates to a container produced in this manner.

Abstract: The invention relates to a container for fluid operating materials of a motor vehicle, comprising at least one container and a heat-exchanging device outside said container. The heat-exchanging device is formed by two half-shells sitting against the container wall outside said container, said half-shells having an inner wall and an outer wall which between at least one flow channel is formed for a heat-transferring medium.

Abstract: A working fluid unit, comprising a container having a temperature-sensitive vehicle working fluid contained therein, in particular for exhaust gas after-treatment, a container mantle which is open at least on one side and in which the vehicle working fluid is introduced and the opening of which is closed by a container lid, wherein the container lid is connected to the container mantle by friction stir welding, magnetic pulse welding, or magnetic pulse crimping, wherein the connecting seam is spaced a distance from the vehicle working fluid that is present.

Abstract: The invention relates to a vehicle tank for liquid fuels, including at least two compartments separated by a baffle, one compartment having a withdrawal line and the baffle having an opening which is close to the bottom and has a valve, and the valve opening independently of a pressure and/or fill level difference in the compartments when the fuel is on the side of the valve facing away from the withdrawal line.

Abstract: The invention relates to a tank for working fluids of motor vehicles, comprising a metal wall, at least one opening therein, and a plastic coating on the inside of the metal wall, wherein the plastic coating extends through the opening at least to the level of the outside of the metal wall.

Abstract: The invention relates to a method for producing a multi-chamber tank for fuels of motor vehicles, said tank comprising at least one internally coated first and at least one internally coated second chamber. The method comprises the following steps: making a first metal tank segment available, said segment containing the first chamber and an externally protruding peripheral collar, rotolining the first tank segment (4) to internally coat the first chamber with a plastic material, and connecting a second metal tank segment to the peripheral collar to form the second chamber between the second tank segment, the peripheral collar and the exterior of the second tank segment, the first tank segment being retained by its peripheral collar during rotolining.
