Abstract: A cartridge for pressurized fluid. The cartridge includes a body having a cylindrical portion and a bottom having a concavity oriented toward the inside of the body. The connection between the bottom and the body is made by an annular seam. The particular structure of the connection zone provides a reduction in the diameter of the body for connection to a bottom of lesser diameter without creating zones of concentration of stresses. Another arrangement of the cartridge provides for the bottom to have a cylindrical portion that bears against the cylindrical end portion of the body, which makes it possible to create a rigid zone.

Abstract: A heating apparatus has a catalytic burner and a thermal receiver which consumes at least one portion of the heat generated by the catalytic burner. The catalytic burner has a member for ejecting a flow of combustible gas, a member for admixing primary air with the flow of combustible gas to obtain a mixture to be burnt, a chamber for distributing the mixture, and a catalytic combustion structure in communication with the distribution chamber. The combustible gas travels into an upstream face of the catalytic combustion structure, and combustion exhaust gases are removed through a downstream face of the catalytic combustion structure. A radiating flameless combustion front is located in the vicinity of the upstream face of the catalytic combustion structure during operation. A thermal receiver extends along virtually the entire surface of the upstream face of the catalytic structure and receives thermal energy.

Abstract: A heating device with a catalytic burner for a fuel gas is equipped with a member for regulating the thermal power. The regulating member includes a metal flap for regulating the flow of the mixture to be burned in the catalytic burner. This flap, for example a heat-sensitive bimetallic strip, can move between two positions, namely a first position in which the mixture to be burned is stored in the device or discharged in the manner of a leakage through an orifice in a wall of the heating device, and a second position which allows a maximum flow rate of the mixture to pass through the catalytic burner. The invention applies to all types of heating devices with a catalytic burner.
