Abstract
Abstract A pulsating fluid is delivered for use in any of a variety of such devices as hygienic appliances and showerheads. An elongated stem has separated inlet and outlet regions each with a respective fluid channel. Included at the outlet region is a valve. A longitudinally elastic sleeve encircles the stem and has its opposing ends sealingly secured individually to respective ones of the inlet region and the valve. The sleeve repetitively responds to fluid under pressure admitted to the inlet to operate the valve into an open condition and then responds to release of the fluid through the outlet so as to operate the valve to a closed condition.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
A fluid pulsator comprising: an elongated stem having an inlet region and an outlet region individually at respective opposite ends of said stem; a first channel in said inlet region communicating between the corresponding end of said stem and a first port in the intermediate sidewall of said stem; a second channel in said outlet region communicating between a second port in the intermediate sidewall of said stem and that corresponding end of said stem; valve means, including a valve and valve seat, disposed on said stem at said outlet region with said valve and valve seat located effectively in the path of said second channel; and a longitudinally-elastic sleeve encircling said stem with its opposing ends sealingly secured individually to respective ones of said valve means and said end of said stem at said inlet region, said sleeve repetitively responding to fluid under pressure admitted through said first channel to operate said valve means to an open condition and then responding to release of said fluid through said second channel to operate said valve means to a closed condition.
Claim 2
Dependent Claim
180 words
A fluid pulsator comprising: an elongated stem having an inlet region and an outlet region individually at respective opposite ends of said stem; a first channel in said inlet region communicating between the corresponding end of said stem and a first port in the intermediate sidewall of said stem; a second channel in said outlet region communicating between a second port in the intermediate sidewall of said stem and that corresponding end of said stem; valve means, including a valve and valve seat, disposed on said stem at said outlet region with said valve and valve seat located effectively in the path of said second channel; and a longitudinally-elastic sleeve encircling said stem with its opposing ends sealingly secured individually to respective ones of said valve means and said end of said stem at said inlet region, said sleeve repetitively responding to fluid under pressure admitted through said first channel to operate said valve means to an open condition and then responding to release of said fluid through said second channel to operate said valve means to a closed condition.
Claim 3
Dependent Claim
20 words
A fluid pulsator as defined in claim 1 which further includes means for adjusting the longitudinal tension in said sleeve.
Claim 4
Dependent Claim
35 words
A fluid pulsator as defined in claim 1 in which a collar is threaded upon said stem over a portion of said inlet region and one end of said sleeve is secured to said collar.
Claim 5
Dependent Claim
50 words
A fluid pulsator as defined in claim 1 in which said valve is secured around said stem between said inlet and outlet regions, said valve seat is defined in a barrel slidable on said stem over said outlet region, and an end of said sleeve is secured to said barrel.
Claim 6
Dependent Claim
28 words
A fluid pulsator as defined in claim 1 which further includes a rigid tube lonGitudinally encircling said sleeve and of a diameter limiting radial expansion of said sleeve.
Claim 7
Dependent Claim
25 words
A fluid pulsator as defined in claim 1 which further includes means in said first channel for selectively varying the volume of fluid flow therethrough.
Claim 8
Dependent Claim
36 words
A fluid pulsator as defined in claim 6 in which said varying means comprises a tube in said first channel and in which said first port is located and means for progressively opening said first port.
Claim 9
Dependent Claim
31 words
A fluid pulsator as defined in claim 1 which further includes a multiply-apertured showerhead nozzle secured to said stem at said outlet region and in fluid communication with said second channel.
Claim 10
Dependent Claim
81 words
A fluid pulsator as defined in claim 1 which further includes a first pipe secured at one end to said stem at said inlet region and in fluid communication with said first channel, a slip-on hose fitting formed on the other end of said first pipe, a second pipe secured at one end to said stem at said outlet region and in fluid communication with said second channel, and a fluid-constricting nozzle formed in the other end of said second pipe.
