Abstract
Abstract A flush valve mounting permitting adjustment of water flow to the requirements of different types of toilet bowl comprises a housing in which a float container with a float therein is removably emplaced. The lower portion of the housing has window apertures through which water can flow from the flush tank into a drain upon lifting of the pipe which carries the valve plate. A wall extending downwardly from the floor of the float container abuts the interior of the window openings, and this wall itself has through-flow apertures separated by webs formed by the wall. The openings in the window apertures are diminished by rotating the float container relative to the housing. This permits the water flow to be adjusted to the requirements of the particular toilet bowl.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
171 words
Flush valve mounting for a flush tank, comprising (a) a housing having in its lower portion at least one window with a through-flow opening; (b) a float container contained in said housing and having a floor; (c) a float in said float container cooperating with an abutment attached to a pipe having said housing, said float container and said float coaxially mounted thereon; (d) a valve plate for a flush valve mounted on the lower end of said pipe, and causing said valve to open when said pipe is lifted, said valve remaining in open position until said float container is substantially empty of water; (e) adjustable means being provided for diminishing the size of said through-flow opening of said at least one window, said adjustable means comprising a downwardly extending annular wall beneath said floor of said float container, said wall having flow-through openings separated be webs, said float container being rotatable relative to said housing, whereby said webs are caused to cover at least a portion of said windows.
Claim 2
Dependent Claim
171 words
Flush valve mounting for a flush tank, comprising (a) a housing having in its lower portion at least one window with a through-flow opening; (b) a float container contained in said housing and having a floor; (c) a float in said float container cooperating with an abutment attached to a pipe having said housing, said float container and said float coaxially mounted thereon; (d) a valve plate for a flush valve mounted on the lower end of said pipe, and causing said valve to open when said pipe is lifted, said valve remaining in open position until said float container is substantially empty of water; (e) adjustable means being provided for diminishing the size of said through-flow opening of said at least one window, said adjustable means comprising a downwardly extending annular wall beneath said floor of said float container, said wall having flow-through openings separated be webs, said float container being rotatable relative to said housing, whereby said webs are caused to cover at least a portion of said windows.
Claim 3
Dependent Claim
44 words
Flush valve mounting according to claim 1, wherein said floor of said float container rests on a shoulder of said housing, said shoulder and said float container having respective coupling means whose mutual engagement prevents rotation of said float container relative to said housing.
Claim 4
Dependent Claim
42 words
Flush valve mounting according to claim 2, wherein the exterior side of said float container is provided with a gear rim engaged by a pinion mounted on an axle rotatably supported on said housing and actuatable by means of a turn button.
Claim 5
Dependent Claim
167 words
Flush valve mounting for a flush tank, comprising (a) a housing having in its lower portion at least one window with a through-flow opening; (b) a float container contained in said housing and having a floor; (c) a float in said float container cooperating with an abutment attached to a pipe having said housing, said float container and said float coaxially mounted thereon; (d) a valve plate for a flush valve mounted on the lower end of said pipe, and causing said valve to open when said pipe is lifted, said valve remaining in open position until said float container is substantially empty of water; (e) adjustable means being provided for diminishing the size of said through-flow opening of said at least one window, said adjustable means comprising an annular member arranged on the exterior side of said housing in the area of said windows, said annular member being height adjustable along said housing, whereby its vertical position determines the extent to which said windows remain unobstructed.
Claim 6
Dependent Claim
167 words
Flush valve mounting for a flush tank, comprising (a) a housing having in its lower portion at least one window with a through-flow opening; (b) a float container contained in said housing and having a floor; (c) a float in said float container cooperating with an abutment attached to a pipe having said housing, said float container and said float coaxially mounted thereon; (d) a valve plate for a flush valve mounted on the lower end of said pipe, and causing said valve to open when said pipe is lifted, said valve remaining in open position until said float container is substantially empty of water; (e) adjustable means being provided for diminishing the size of said through-flow opening of said at least one window, said adjustable means comprising an annular member arranged on the exterior side of said housing in the area of said windows, said annular member being height adjustable along said housing, whereby its vertical position determines the extent to which said windows remain unobstructed.
