MOTOR VEHICLE HEATING DEVICE

摘要

The invention relates to a motor vehicle heating device with a burner, to which combustion air is supplied via combustion air inlet openings by means o f a fan and to which fuel gas is supplied via a fuel gas supply line, the combusti on air and the fuel gas entering on the intake side of the fan. It is provided accordi ng to the invention, for a simpler structure and good mixing of the fuel gas/combustio n air mixture, that entry of fuel gas is controlled by means of a valve or switch cont rolled by the negative pressure of the fan. Fuel gas is supplied in doing so, preferab ly with a negative pressure which is less than atmospheric pressure. For especiall y-simple control of gas supply, there is a membrane which causes the fuel gas supp ly line to close when the fan stops.
