Claim 1
Independent Claim
210 words
A device for pre-vaporising liquid fuel, designed for application for a combustion system comprising a combustion chamber, a liquid fuel source and a source of combustion agent such as air, said pre-vaporisation device comprising a hollow structure adapted to project into the combustion chamber and having a general T-shape, said hollow structure being made up of a body, which constitutes the leg of the T and is connected to said liquid fuel and combustion agent sources, and two transverse arms connected to said body and terminating, in each case, in a discharge orifice which opens into the combustion chamber and through which, in operation, there escapes a flow made up of a mixture of combustion agent and fuel in an at least partially vaporised state, a thin-walled diaphragm being provided in the neighborhood of the armpits where the transverse arms join the body of the hollow structure to partially close off said body, said diaphragm comprising two thin partitions each presenting a sharp edge disposed toward the axis of said body and toward the similar sharp edge belonging to the particular other partition, said partitions between said mutually opposite edges defining a restricted flow passage through which the body of the hollow structure communicates with each of said transverse arms.
Claim 2
Independent Claim
210 words
A device for pre-vaporising liquid fuel, designed for application for a combustion system comprising a combustion chamber, a liquid fuel source and a source of combustion agent such as air, said pre-vaporisation device comprising a hollow structure adapted to project into the combustion chamber and having a general T-shape, said hollow structure being made up of a body, which constitutes the leg of the T and is connected to said liquid fuel and combustion agent sources, and two transverse arms connected to said body and terminating, in each case, in a discharge orifice which opens into the combustion chamber and through which, in operation, there escapes a flow made up of a mixture of combustion agent and fuel in an at least partially vaporised state, a thin-walled diaphragm being provided in the neighborhood of the armpits where the transverse arms join the body of the hollow structure to partially close off said body, said diaphragm comprising two thin partitions each presenting a sharp edge disposed toward the axis of said body and toward the similar sharp edge belonging to the particular other partition, said partitions between said mutually opposite edges defining a restricted flow passage through which the body of the hollow structure communicates with each of said transverse arms.
Claim 3
Dependent Claim
32 words
A device as claimed in claim 1, in which said thin-walled diaphragm is located at the level of the armpits where the said transverse arms join the body of the hollow structure.
Claim 4
Dependent Claim
48 words
A device as claimed in claim 1, in which said thin-walled diaphragm is located downstream (considered in relation to the direction of flow of the mixture of combustion agent and fuel through said body of the hollow structure) of the armpits where said transverse arms join said body.
Claim 5
Dependent Claim
58 words
A device as defined in claim 3, in which additional passages are provided through which said body of said hollow structure communicates with each of said arms, said additional passages originating in said body up-stream of said thin-walled diaphragm and opening into said transverse arms directly in the zones of the armpits where said arms join the body.
Claim 6
Dependent Claim
33 words
A device as claimed in claim 4, in which said additional passages are aligned in a direction which has a component disposed transversely of the axis of said body of said hollow structure.
Claim 7
Dependent Claim
36 words
A device as claimed in claim 1, in which said thin-walled partitions each contain at least one orifice disposed in a direction having a component parallel to the axis of said body of said hollow structure.
