Abstract
A fuel connection unit (10) for a fuel-operated vehicle heater (18) includes a connection unit body (12), which can be arranged at a heater housing (16). A fuel release line connection area (32) connects a fuel release line leading to a combustion chamber. A fuel feed line connection area (46) projects from the connection unit body (12) for connecting a fuel feed line. At least one functional unit (50), for influencing the flow of fuel in a fuel flow volume (36) formed in the connection unit body (12), is provided in the connection unit body (12).
Claims15
A fuel-operated vehicle heater comprising:
- a heater housing having a fuel connection unit receiving opening;
- and a fuel connection unit connected to the heater housing, the fuel connection unit comprising:
- a connection unit body inserted into the fuel connection unit receiving opening of the heater housing, and surrounded by a sealing element clamped between an outer circumference of the connection unit body and the heater housing, a fuel flow volume being provided in the connection unit body;
- a fuel release line connection area configured as a pipe branch and projecting from the connection unit body on a side of the connection unit body facing an interior of the heater housing, the fuel release line connection area providing a fuel duct open towards the fuel flow volume in the connection unit body;
- a fuel release line connected to the fuel release line connection area and leading to a combustion chamber;
- a fuel feed line connection area configured as a pipe branch and projecting from the connection unit body on a side of the connection unit body facing outwards for connecting a fuel feed line, the fuel feed line connection area providing a fuel duct open towards the fuel flow volume in the connection unit body;
- and at least one functional unit for influencing a flow of fuel in the fuel flow volume, the at least one flow influencing means being provided in the connection unit body.
