Abstract

An evaporator assembly ( 10 ), in particular for a fuel-operated vehicle heater ( 12 ), comprising a pot-like evaporator reception ( 14 ), an evaporator body ( 16 ) inserted into the pot-like evaporator reception ( 14 ), a plate-like designed hold-down element ( 18 ), which is fixed to the evaporator reception ( 14 ) and fixes the evaporator body ( 16 ) in the evaporator reception ( 14 ), and wherein the plate-like designed hold-down element ( 18 ) has at least one retaining claw ( 22 ), which has an upper part ( 26 ) on an upper side ( 24 ) of the plate-like designed hold-down element ( 18 ) and a lower part ( 30 ) on a lower side ( 28 ) of the plate-like designed hold-down element ( 18 ), wherein the upper part ( 26 ) and the lower part ( 30 ) point away from the plate-like designed hold-down element ( 18 ).

First claim

The invention claimed is:

1. Evaporator assembly for a fuel-operated vehicle heater, comprising
a pot-like evaporator reception,
an evaporator body inserted into the pot-like evaporator reception,
a plate-like designed hold-down element, which is fixed to the evaporator reception and fixes the evaporator body in the evaporator reception, and
wherein the plate-like designed hold-down element has at least one retaining claw, which has an upper part on an upper side of the plate-like designed hold-down element and a lower part on a lower side of the plate-like designed hold-down element,
wherein the upper part and the lower part point away from the plate-like designed hold-down element.

2. Evaporator assembly according to claim 1 , wherein the plate-like designed hold-down element is connected to the evaporator reception in a substance-bonded manner or is caulked against the evaporator reception.

3. Evaporator assembly according to claim 1 , wherein the plate-like designed hold-down element is substantially annular-disk-like.

4. Evaporator assembly according to claim 1 , wherein the lower part of the at least one retaining claw abuts against the evaporator body in the evaporator reception and/or penetrates into the evaporator body.

5. Evaporator assembly according to claim 1 , wherein the upper part and the lower part ( 30 ) have the same shape.

6. Fuel-operated vehicle heater having an evaporator assembly according to claim 1 .
