<p>Subject of the invention is a diesel fuel heater for road vehicles. The heater according to the invention is characterised in that from the bottom of the enclosure (1) there are vertically, this means axially designed guides (6) which are preferably cylinder-shaped and in the part along the enclosure (1) of enhanced diameter while after that they are staggered to result in a smaller diameter, and the height of the guides (6) at their smaller diameter is smaller from the height of the heating elements (5), while the guides (7) are preferably cylinder-shaped, preferably of equal or similar diameter as the smaller diameter of guides (6) and the height of the guides (7) features a size by which they reach slightly, preferably approximately 1 mm above the height of the heating elements (5) and that onto the assembly consisting of the lower panel (3), heating elements (5) and upper panel (4) the legs (8b) of the leg- shaped spring (8) are pressing. The leg-shaped spring (8) is slid on a pillar (9) and features alternating legs (8b) looking down and up (8c), while the number of the legs looking down (8b) is equal to the number of heating elements (5) so that the legs (8b) are designed in such a way that they press against the upper panel (4) in places, where the heating elements (5) are located underneath.</p> |
