Abstract

The absorbing device includes a hollow enclosed chamber including two pot parts. Open ends of the pot parts are connectable to each other by welding or soldering. Each of the pot parts is integrally formed in an opposing end of an air-conditioning conduit, wherein open ends of the pot parts are oriented toward each other. Each of the pot parts is provided with a reduced passage opening interconnected with an internal space of the air-conditioning conduit via a tapered section.

First claim

The invention claimed is:

1. An absorbing device for an air-conditioning system, comprising:
a first pot part integrally formed in an end of a first air conditioning conduit; and
a second pot part cooperating with the first pot part to form a hollow enclosed chamber, the second pot part integrally formed in an end of a second air conditioning conduit, an open end of the first pot part connected to an open end of the second pot part, each of the first pot part and the second pot part including a passage therein to provide fluid communication between the hollow enclosed chamber and respective internal spaces of the first air conditioning conduit and the second air conditioning conduit;
a first tapered section formed between the first air conditioning conduit and the passage of the first pot part, wherein a diameter of the passage of the first pot part is less than a diameter of the internal space of the first air conditioning conduit, wherein a diameter of the first tapered section gradually tapers along a length of the first tapered section from the air conditioning conduit to the passage of the first pot part, and wherein the first air conditioning conduit is spaced from the passage of the first pot part with respect to an axial direction of the passage of the first pot part; and
a second tapered section formed between the second air conditioning conduit and the passage of the second pot part, wherein a diameter of the passage of the second pot part is less than a diameter of the internal space of the second air conditioning conduit, wherein a diameter of the second tapered section gradually tapers along a length of the second tapered section from the air conditioning conduit to the passage of the second pot part, and wherein the second air conditioning conduit is spaced from the passage of the second pot part with respect to an axial direction of the passage of the second pot part.

2. The absorbing device of claim 1 , wherein the first tapered section of the first pot part is formed separate from the first pot part and the first air conditioning conduit.

3. The absorbing device of claim 2 , wherein the second tapered section of the second pot part is formed separate from the second pot part and the second air conditioning conduit.

4. The absorbing device of claim 1 , wherein the open end of the first pot part is joined to the open end of the second pot part by welding.

5. The absorbing device of claim 1 , wherein the open end of the first pot part is joined to the open end of the second pot part by soldering.

6. A method of forming an absorbing device, comprising:
providing a first conduit having an end:
providing a second conduit having an end;
ramming the end of the first conduit to reduce an internal diameter and increase a wall thickness of the end of the first conduit, wherein an outer diameter of the first conduit is retained, wherein the ramming of the end of the first conduit forms a first tapered section; and
ramming the end of the second conduit to reduce an internal diameter and increase a wall thickness of the end of the second conduit, wherein an outer diameter of the second conduit is retained, wherein the ramming of the end of the second conduit forms a second tapered section;
widening a distal portion of the end of the first conduit to form a first pot part having an open end, wherein the first pot part includes a passage therein to provide fluid communication between the first pot part and the first conduit, wherein the first tapered section is formed adjacent the passage of the first pot part, wherein a diameter of the passage of the first pot part is less than the internal diameter of the first conduit, wherein a diameter of the first tapered section gradually tapers along a length of the first tapered section from a portion of the first conduit to the passage of the first pot part, and wherein the portion of the first conduit is spaced from the passage of the first pot part with respect to an axial direction of the passage of the first pot part;
widening a distal portion of the end of the second conduit to form a second pot part having an open end, wherein the second pot part includes a passage therein to provide fluid communication between the second pot part and the second conduit, wherein the second tapered section is formed adjacent the passage of the second pot part, wherein a diameter of the second tapered section gradually tapers along a length of the second tapered section from a portion of the second conduit to the passage of the second pot part, and wherein the portion of the second conduit is spaced from the passage of the second pot part with respect to an axial direction of the passage of the second pot part; and
joining the open end of the first pot part to the open end of the second pot part to form a hollow enclosed chamber.

7. The method of claim 6 , further comprising forming a peripheral flange circumscribing the open end of the first pot part.

8. The method of claim 7 , wherein the open end of the second pot part is received by the peripheral flange of the first pot part.

9. The method of claim 6 , wherein the first pot part is joined to the second pot part by welding.

10. The method of claim 6 , wherein the first pot part is joined to the second pot part by soldering.
