Abstract
An aspirator configured to be received within a shower fitting for generating a negative pressure in response to water flow.
Claims16
A shower fitting comprising:
- a housing including an inlet, a first outlet, a second outlet, and an inner surface defining a bore in fluid communication with the inlet, the first outlet and the second outlet;
- an aspirator including a body received within the bore, the body including a first end, a second end, and a sidewall defining an inner passageway extending along a longitudinal axis between the first end and the second end, the sidewall including a plurality of longitudinally extending flutes having a plurality of concave recesses extending between the sidewall of the aspirator and the inner surface of the bore, the flutes extending from proximate the first end of the body in fluid communication with the inlet of the housing to proximate the second end of the body in fluid communication with the second outlet of the housing;
- and
- an outer passageway extending between the plurality of recesses of the aspirator and the inner surface of the bore, the outer passageway including a first end sealed from the first outlet, and a second end in open communication with the second outlet such that a negative pressure is exerted on the inner passageway by fluid flow through the outer passageway to the second outlet.

A shower fitting comprising:
- a housing configured to receive a flow control valve, the housing including an inner surface defining a bore;
- an inlet, a first outlet, and a second outlet fluidly coupled to the first outlet by the bore;
- an aspirator including a body received within the bore, the body including a first end, a second end, and a sidewall defining an inner passageway extending along a longitudinal axis between the first end and the second end, the sidewall including a plurality of longitudinally extending flutes having a plurality of recesses, and a plurality of lands separating the plurality of recesses, wherein the flutes taper inwardly toward the longitudinal axis as the flutes extend in a longitudinal direction from the second end toward the first end, at least a portion of each flute configured to provide an interference fit with the inner surface of the bore;
- and
- an outer passageway extending between the plurality of recesses of the aspirator and the inner surface of the bore, wherein the first end of the body includes an end wall sealingly engaging the inner surface of the bore for sealing the outer passageway from the first outlet.

An aspirator for being positioned in a shower fitting having a vertical bore with a lower outlet and an upper outlet, the aspirator comprising:
- a lower end;
- an upper end spaced above the lower end and sealingly engaging an inner surface of the vertical bore between the lower outlet and the upper outlet;
- a sidewall defining an inner passageway extending between the lower end and the upper end;
- and
- a plurality of longitudinally extending flutes supported by the sidewall and extending from the lower end toward the upper end, the flutes including a plurality of concave recesses within the vertical bore of the shower fitting, and a plurality of lands separating the plurality of recesses, the recesses in open communication with the lower outlet, wherein the flutes taper inwardly as the flutes extend from the lower end toward the upper end.
