Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
184 words
A fluid injector apparatus for a bath enclosure, comprising: a check valve which includes a body having an outlet, a truncated cone-shaped valve seat and a ring member with a bottom portion which defines apertures for the passage of fluid and an axial aperture, said valve further including a disc defining a peripheral groove and having a seal seated therein for sealing engagement with the valve seat, and a rod slidably received in the axial aperture for carrying the disc; and a swiveling injector which includes a sleeve having an end flange at one end, said sleeve being threadably received in the valve body outlet, said injector further including a tube rotatably carried within the sleeve and having a head member adapted to substantially cover and bear against the sleeve end flange, said head member defining an oblique aperture, and said tube defining a conduit fluidically coupling the valve outlet to the head member aperture, and an external seal groove around the periphery of the tube, and said injector further including a seal received in the tube seal groove and bearing against the sleeve.
Claim 2
Dependent Claim
184 words
A fluid injector apparatus for a bath enclosure, comprising: a check valve which includes a body having an outlet, a truncated cone-shaped valve seat and a ring member with a bottom portion which defines apertures for the passage of fluid and an axial aperture, said valve further including a disc defining a peripheral groove and having a seal seated therein for sealing engagement with the valve seat, and a rod slidably received in the axial aperture for carrying the disc; and a swiveling injector which includes a sleeve having an end flange at one end, said sleeve being threadably received in the valve body outlet, said injector further including a tube rotatably carried within the sleeve and having a head member adapted to substantially cover and bear against the sleeve end flange, said head member defining an oblique aperture, and said tube defining a conduit fluidically coupling the valve outlet to the head member aperture, and an external seal groove around the periphery of the tube, and said injector further including a seal received in the tube seal groove and bearing against the sleeve.
Claim 3
Dependent Claim
61 words
The apparatus of claim 1 wherein the rod has a head member at one end and the check valve further comprises a spring disposed around the rod which bears on the one hand against the valve ring member and on the other hand against the rod head to thereby urge the valve disc seal in sealing engagement with the valve seat.
Claim 4
Dependent Claim
43 words
The apparatus of claim 1 wherein the valve body comprises two parts each of which has an internal collar, said valve body parts being threadably coupled together wherein the ring member is gripped between the two internal collars of the valve body parts.
Claim 5
Dependent Claim
50 words
The apparatus of claim 1 wherein the ring member defines a peripheral recess at one end of its external surface, the check valve further comprising a toric seal received within the ring member peripheral recess, which is positioned in sealing engagement with the junction of the two valve body parts.
Claim 6
Dependent Claim
127 words
A fluid injector apparatus for a bath enclosure, comprising: a non-return valve which includes a body, a ring member having a frustoconical valve seat at one end and a plurality of fluid orifices and an axial orifice at the other end, a rod slidably carried within the axial orifice, a disc carried by the rod and shaped to sealingly engage the valve seat, said disc defining a peripheral groove and having a toric seal seated in the disc groove; and a directional injector threadably coupled to the valve body, which includes a sleeve having an end collar and a tube which has an orientable head portion covering the sleeve end collar, the head portion having an inclined orifice fluidically coupled to the interior of the valve body.
Claim 7
Dependent Claim
127 words
A fluid injector apparatus for a bath enclosure, comprising: a non-return valve which includes a body, a ring member having a frustoconical valve seat at one end and a plurality of fluid orifices and an axial orifice at the other end, a rod slidably carried within the axial orifice, a disc carried by the rod and shaped to sealingly engage the valve seat, said disc defining a peripheral groove and having a toric seal seated in the disc groove; and a directional injector threadably coupled to the valve body, which includes a sleeve having an end collar and a tube which has an orientable head portion covering the sleeve end collar, the head portion having an inclined orifice fluidically coupled to the interior of the valve body.
Claim 8
Dependent Claim
61 words
The apparatus of claim 5 wherein the rod has a head member at one end and the check valve further comprises a spring disposed around the rod which bears on the one hand against the valve ring member and on the other hand against the rod head to thereby urge the valve disc seal in sealing engagement with the valve seat.
Claim 9
Dependent Claim
43 words
The apparatus of claim 5 wherein the valve body comprises two parts each of which has an internal collar, said valve body parts being threadably coupled together wherein the ring member is gripped between the two internal collars of the valve body parts.
Claim 10
Dependent Claim
50 words
The apparatus of claim 5 wherein the ring member defines a peripheral recess at one end of its external surface, the check valve further comprising a toric seal received within the ring member peripheral recess, which is positioned in sealing engagement with the junction of the two valve body parts.
Claim 11
Dependent Claim
30 words
The apparatus of claim 5 wherein the tube has an external peripheral groove and the apparatus further comprises a seal received in the tube groove which bears against the sleeve.
Claim 12
Dependent Claim
20 words
An injector according to any of the preceeding claims wherein the sleeve is externally screw threaded to the valve body.
