Abstract:
1. An apparatus for cleaning a nozzle comprising: a L-shape rigid body member having an inlet port and an exit port at opposite ends thereof, and a L-shaped internal passage extending between said inlet port and said exit port; wherein said inlet port has (i) an outer annular portion disposed at the entrance of said inlet port, said outer annular portion being coaxially aligned with said passage and having a constant diameter larger than the diameter of said passage, and (ii) an inner annular portion disposed between said outer annular portion and said passage, said inner annular portion being co-axially aligned with said passage, and having a constant diameter larger than the diameter of said passage and smaller than the diameter of said outer annular portion; wherein a first flat shoulder portion is formed at a junction of said outer annular portion and said inner annular portion, and a second flat shoulder portion is formed at a junction of said inner annular portion and said passage; wherein the diameters of said inner and outer annular portions are configured to fit differently-sized dispensing tubes of cans of pressurized solvent and the first and second flat shoulder portions limit insertion of the dispensing tubes into said passage, creating a seal between the end of a dispensing tube and a shoulder portion; wherein said exit port has (i) an annular beveled region at the exit of said exit port, said beveled region having a large diameter and a small diameter, and (ii) an annular exit portion disposed between said beveled region and said passage, said exit portion being co-axially aligned with said passage, and having a constant diameter equal to the small diameter of said beveled region and larger than the diameter of said passage; wherein said passage has a tapered region adjacent to said annular exit portion, said tapered region having a large diameter and a small diameter, wherein said large diameter of said tapered region is equal to the diameter of said annular exit portion; and wherein said body member further comprises a cupped contact surface having a centerline substantially co-axially aligned with said inner and outer annular portions of said inlet port.
