Abstract
Abstract A whirlpool jet assembly adapted to be mounted in an opening in the wall of a water tub for discharging the water stream into the tub. The jet assembly includes a housing defining a socket having an air inlet and a water inlet and a ball fitting pivotably supported within the socket having openings positionable in alignment with the air and water inlets in the socket. A nozzle assembly supported on the ball fitting is of a unitary one-piece construction forming a Venturi nozzle, mixing chamber and directional nozzle in an integral structure. The nozzle assembly is rotatably supported on the ball fitting with the ball fitting and nozzle assembly having shaped openings through which water from the water inlet flows into the Venturi jet nozzle. Rotation of the nozzle assembly with respect to the ball fitting changes the combined shape of the shaped openings to alter the pressure of water flowing through the jet assembly.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
A whirlpool jet assembly adapted to be mounted in an opening in the wall of a water tub for discharging a water stream into said tub, comprising a housing defining a socket having an air inlet and a water inlet, a ball fitting pivotally supported within said socket and having openings positionable in alignment with said air inlet and water inlet in said socket, a nozzle assembly supported on said ball fitting, said nozzle assembly being a unitary one-piece construction and forming a Venturi nozzle, mixing chamber and directional nozzle in an integral structure, said nozzle assembly being rotatably supported on said ball fitting, said ball fitting and nozzle assembly having shaped openings through which water from said water inlet can flow into said Venturi jet nozzle, rotation of said nozzle assembly with respect to said ball fitting changing the combined shape of said shaped openings to alter the pressure of water flowing through the jet assembly.
Claim 2
Dependent Claim
157 words
A whirlpool jet assembly adapted to be mounted in an opening in the wall of a water tub for discharging a water stream into said tub, comprising a housing defining a socket having an air inlet and a water inlet, a ball fitting pivotally supported within said socket and having openings positionable in alignment with said air inlet and water inlet in said socket, a nozzle assembly supported on said ball fitting, said nozzle assembly being a unitary one-piece construction and forming a Venturi nozzle, mixing chamber and directional nozzle in an integral structure, said nozzle assembly being rotatably supported on said ball fitting, said ball fitting and nozzle assembly having shaped openings through which water from said water inlet can flow into said Venturi jet nozzle, rotation of said nozzle assembly with respect to said ball fitting changing the combined shape of said shaped openings to alter the pressure of water flowing through the jet assembly.
Claim 3
Dependent Claim
22 words
The whirlpool jet assembly as claimed in claim 1, wherein said ball fitting includes a recessed region for receiving said nozzle assembly.
Claim 4
Dependent Claim
27 words
The whirlpool jet assembly as claimed in claim 1, wherein said ball fitting can be pivoted with respect to said air and water inlets in said socket.
Claim 5
Dependent Claim
52 words
The whirlpool jet assembly as claimed in claim 1, wherein said nozzle assembly includes an opening adjacent the tip of said Venturi nozzle to permit air from said air inlet flowing through said ball fitting to mix with the jet stream of water emerging from said Venturi nozzle in said mixing chamber.
Claim 6
Dependent Claim
32 words
The whirlpool jet assembly as claimed in claim 1, wherein said nozzle assembly is pivotable with said ball fitting to permit adjustment of the flow direction of the water into said tub.
Claim 7
Dependent Claim
26 words
The whirlpool jet assembly as claimed in claim 1, wherein said shaped openings in said ball fitting and nozzle assembly are essentially cross-shaped in plan view.
Claim 8
Dependent Claim
44 words
The whirlpool jet assembly as claimed in claim 1, wherein said ball fitting includes a projection and said nozzle assembly includes a slot in which said projection extends to limit the amount of rotation of said nozzle assembly with respect to said ball fitting.
Claim 9
Dependent Claim
22 words
The whirlpool jet assembly as claimed in claim 5, wherein said nozzle assembly can be pivoted through an angle of about 20°.
Claim 10
Dependent Claim
32 words
The whirlpool jet assembly as claimed in claim 1, further comprising light means supported on said housing and positioned essentially in line with said nozzle assembly for directing light into said tub.
Claim 11
Dependent Claim
36 words
The whirlpool jet assembly as claimed in claim 9, wherein said light means includes a light tube positioned essentially in line with said nozzle assembly and a light source for directing light to said light tube.
