Temperature-controlled fuel valve, especially for a fuel-operated heating burner of a vehicle heating system

A heating system, comprising:

• a heating burner with a combustion chamber;
• a pump arrangement for delivering fuel to the combustion chamber;
• and
• a temperature-controlled fuel valve in the flow path between the pump arrangement and the combustion chamber, the fuel valve including a valve member that is adjustable as a function of a temperature in the area of a heating burner.

A vehicle heating system fuel-operated heating burner temperature-controlled fuel valve, comprising:

• a valve body;
• a valve member that is adjustable in said valve body as a function of a temperature in the area of a heating burner, the valve body defining a feed area and two drain areas, the valve member interrupting a connection between the feed area and the two drain areas at a temperature in a first temperature range, the valve member not interrupting the connection between the feed area and the two drain areas at a temperature in a second temperature range that is higher than the first temperature range, and the valve member not interrupting the connection between the feed area and one of the drain areas and interrupts the connection between the feed area and the other of the drain areas at a temperature in a third temperature range that is higher than the second temperature range;
• a temperature sensor arrangement with a temperature sensor medium with temperature-dependent volume;
• and
• a transmission arrangement that can be displaced by a change in the volume of the temperature sensor medium and acts on the valve member.
