Abstract
The present invention provides a fluid dispensing apparatus and a method of manufacturing a fluid dispensing apparatus.
Claims21
A fluid dispensing apparatus, comprising:
- an apparatus inlet through which fluid is received into the apparatus;
- an apparatus outlet through which fluid is dispensed from the apparatus;
- an apparatus passageway extending from the apparatus inlet to the apparatus outlet;
- a core, the core being formed from a metal alloy, the core metal alloy having a melting point, the core having an inner surface and an outer surface, the core having a core inlet and a core outlet, the core having a core passageway extending from the core inlet to the core outlet;
- and
- a shell, the shell being formed from a metal alloy, the shell metal alloy having a melting point, the shell being cast around the outer surface of the core, the shell being in direct contact with the outer surface of the core;
- wherein, as cast, at least one of:
- the core inlet is coextensive with the apparatus inlet, and the core outlet is coextensive with the apparatus outlet;
- and wherein the melting point of the core metal alloy is approximately the same as the melting point of the shell metal alloy.

A method of manufacturing a fluid dispensing apparatus, comprising the steps of:
- forming an apparatus passageway having an apparatus inlet and an apparatus outlet, fluid being received into the apparatus through the apparatus inlet, fluid being dispensed from the apparatus through the apparatus outlet, the apparatus passageway extending from the apparatus inlet to the apparatus outlet;
- wherein the step of forming the apparatus passageway includes at least the steps of:
- forming a core, the core being formed from a metal alloy, the core metal alloy having a melting point, the core having an inner surface and an outer surface, the core having a core inlet and a core outlet, the core having a core passageway extending from the core inlet to the core outlet;
- and
- casting a shell around the outer surface of the core, the shell being in direct contact with the outer surface of the core, the shell being formed from a metal alloy, the shell metal alloy having a melting point;
- wherein, as cast, at least one of:
- the core inlet is coextensive with the apparatus inlet, and the core outlet is coextensive with the apparatus outlet;
- and wherein the melting point of the core metal alloy is approximately the same as the melting point of the shell metal alloy.
