Definitions
- the present invention relates to a discharge device for a flush tank, of the type permitting full or partial discharge of the water in the tank.
- flush tank discharge devices which, to reduce water consumption, permit full or partial discharge as required.
- Such devices normally comprise a discharge valve fitted to the bottom end of a movable pull member (normally the overflow pipe of the tank itself) and which, to discharge water from the tank, is lifted out of its seat using either of two control levers; and the two discharge modes (full or partial) are achieved by varying the speed with which the valve, once raised, closes by force of gravity.
- Two floats are also known to be used, one acting on the closing valve in both modes, and the other only for partial discharge.
- discharge devices of the type briefly described above call for a float; an auxiliary member (additional weight or float) for altering the thrust exerted by the float as the valve closes; and appropriate reversible connecting means between the auxiliary member and the valve.
- Such devices therefore involve a relatively large number of components and are relatively bulky and unreliable.
- FR-A-2678300 discloses a device including a main valve carried by an operating rod which is slidably housed in a vessel and is associated to a float; the vessel presents a bottom wall having a first orifice, and a lateral wall having a second discharge orifice provided with an auxiliary valve operatively connected to the main valve.
- This device is quite complicated and relatively large and requires a relatively large number of component parts.
- a discharge device for a flush tank designed to selectively permit full or partial discharge of the water in said flush tank as claimed in claim 1.
- the discharge device according to the invention therefore provides, simply and effectively, for selectively discharging different amounts of water from the flush tank to which it is fitted.
- the device also comprises a relatively small number of component parts (in particular, only one float), is extremely compact, can be fitted quickly and easily to flush tanks of different sizes, and is cheap to produce, easy to operate and reliable.
- the amount of water discharged in partial-discharge mode can also be regulated easily and effectively by varying the section of the drain openings in the flood chamber in which the float moves, and by appropriately sizing the float itself in relation to the weight of the other component parts of the device.
- Number 1 in Figures 1 and 2 indicates as a whole a discharge device for a known flush tank not shown for the sake of simplicity.
- Device 1 comprises a supporting structure 2 fittable to the flush tank, e.g. by inserting a tubular end portion 3 of supporting structure 2 in fluidtight manner inside a drain hole in the flush tank; in which case, a bottom opening in tubular portion 3 of supporting structure 2 defines the drain hole of the flush tank, and is therefore indicated hereinafter as drain hole 4 for the sake of simplicity.
- Device 1 also comprises a main valve 5 for closing drain hole 4, and which is fitted to the bottom end of a pipe 6 housed in sliding manner inside supporting structure 2 and possibly formed in a number of pieces connected to one another.
- pipe 6 also acts as an overflow pipe of the flush tank.
- Supporting structure 2 has openings 7 at the bottom, through which water flows from the flush tank to drain hole 4, and is fitted inside with a substantially toroidal vessel 8 having an inner flood chamber 9 defined by an inner lateral wall 13 and an outer lateral wall 14 of vessel 8, which are substantially cylindrical and coaxial with each other.
- Inner lateral wall 13 defines, internally, a seat 15 in which pipe 6 slides; and vessel 8 is open at the top and closed at the bottom by an annular bottom wall 16 in which is formed a through, e.g. annular, outflow opening 17 defined by an annular sealing edge 18.
- a number of through outflow openings e.g. arranged side by side circumferentially, are formed in bottom wall 16 of vessel 8.
- auxiliary valve means 19 for selectively opening and closing outflow opening 17 in vessel 8.
- auxiliary valve means 19 comprise a substantially annular shutter member 20, which cooperates with sealing edge 18 to close outflow opening 17, and is connected integrally to a pull member 21 slidable with respect to vessel 8.
- pull member 21 comprises a cylindrical body 22 and a control rod 23;
- cylindrical body 22 is coaxial with, located radially outwards of, and slides axially with respect to, inner lateral wall 13 of vessel 8, and is fitted at the bottom end with shutter member 20; and control rod 23 is fitted to cylindrical body 22 and extends vertically and parallel to pipe 6 at the opposite end to shutter member 20.
- a float 25 e.g. a known substantially toroidal type, is housed freely inside flood chamber 9.
- Device 1 also comprises a stop member 26 for arresting float 25 and connected integrally to main valve 5.
- stop member 26 is defined by a collar 28 fitted integrally about pipe 6 at a predetermined distance from main valve 5, and from a peripheral edge of which a substantially truncated-cone-shaped lateral wall 29 extends downwards inside flood chamber 9 of vessel 8.

- Figure 2 shows device 1 in the rest position : main valve 5 is positioned closing drain hole 4; shutter member 20 closes outflow opening 17 of vessel 8; open-topped vessel 8 is immersed in the water inside the flush tank to which device 1 is fitted, so that flood chamber 9 of vessel 8 is full of water; float 25 is retained inside flood chamber 9 by stop member 26; the total weight of main valve 5 and pipe 6 is greater than the buoyancy of float 25; connecting member 35 is in a rest position 35a ( Figure 2) in which eccentric portion 39 rests on a peripheral edge 42 of supporting structure 2, e.g. defined by a top edge of vessel 8, which defines a retaining member for retaining connecting member 35 in rest position 35a; and main valve 5 and auxiliary valve means 19 are therefore disconnected.
- Figure 3 shows operation of device 1 when full discharge of the water in the flush tank is activated : by means of appropriate known actuating means, not shown for the sake of simplicity, pipe 6 and valve 5 fitted to it are raised to open drain hole 4 and allow the water in the flush tank to flow out; shutter member 20, on the other hand, remains closing outflow opening 17 in vessel 8 (fixed); and connecting member 35 remains in rest position 35a.
- Figure 4 shows operation of device 1 when partial discharge of the water in the flush tank is activated : in this case, the actuating means (not shown) act directly on pull member 21, which is raised together with shutter member 20 to detach shutter member 20 from sealing edge 18 of outflow opening 17 in vessel 8 (fixed). As it moves up, pull member 21 also raises pipe 6, as stop portion 31 of pull member 21 contacts and pushes stop portion 32 of pipe 6, so that the same movement of pull member 21 provides for opening both outflow opening 17 in vessel 8 and drain hole 4 in the flush tank.

Abstract
Description
- The present invention relates to a discharge device for a flush tank, of the type permitting full or partial discharge of the water in the tank.
- Numerous flush tank discharge devices are known which, to reduce water consumption, permit full or partial discharge as required. Such devices normally comprise a discharge valve fitted to the bottom end of a movable pull member (normally the overflow pipe of the tank itself) and which, to discharge water from the tank, is lifted out of its seat using either of two control levers; and the two discharge modes (full or partial) are achieved by varying the speed with which the valve, once raised, closes by force of gravity.
- Devices are known, for example, in which, when raised using the full-discharge lever, the discharge valve is kept open by a float until all the water is drained out of the tank; conversely, for partial discharge, the valve is raised together with an additional weight which, as the valve closes, acts on the valve, in opposition to the thrust exerted by the float, to close the valve faster.
- Two floats are also known to be used, one acting on the closing valve in both modes, and the other only for partial discharge.
- Generally speaking, therefore, discharge devices of the type briefly described above call for a float; an auxiliary member (additional weight or float) for altering the thrust exerted by the float as the valve closes; and appropriate reversible connecting means between the auxiliary member and the valve. Such devices therefore involve a relatively large number of components and are relatively bulky and unreliable.
- FR-A-2678300 discloses a device including a main valve carried by an operating rod which is slidably housed in a vessel and is associated to a float; the vessel presents a bottom wall having a first orifice, and a lateral wall having a second discharge orifice provided with an auxiliary valve operatively connected to the main valve. This device is quite complicated and relatively large and requires a relatively large number of component parts.
- It is an object of the present invention to overcome the aforementioned drawbacks of known discharge devices by providing a flush tank discharge device permitting effective, reliable, full or partial discharge of the water in the tank. It is a further object of the invention to provide a discharge device comprising a relatively small number of component parts, and which is easy to operate, reliable, extremely compact, cheap to produce, and easy to install.
- According to the present invention, there is provided a discharge device for a flush tank, designed to selectively permit full or partial discharge of the water in said flush tank as claimed in
claim 1. - The discharge device according to the invention therefore provides, simply and effectively, for selectively discharging different amounts of water from the flush tank to which it is fitted. The device also comprises a relatively small number of component parts (in particular, only one float), is extremely compact, can be fitted quickly and easily to flush tanks of different sizes, and is cheap to produce, easy to operate and reliable.
- The amount of water discharged in partial-discharge mode can also be regulated easily and effectively by varying the section of the drain openings in the flood chamber in which the float moves, and by appropriately sizing the float itself in relation to the weight of the other component parts of the device.
- A non-limiting embodiment of the present invention will be described by way of example with reference to the accompanying drawings, in which:
- Figure 1 shows a side view of a flush tank discharge device in accordance with the invention;
- Figure 2 shows a section along line II-II of the Figure 1 device in the rest position;
- Figure 3 shows a longitudinal section of the Figure 1 device in full discharge mode;
- Figure 4 shows a longitudinal section of the Figure 1 device in partial-discharge mode.

-
Number 1 in Figures 1 and 2 indicates as a whole a discharge device for a known flush tank not shown for the sake of simplicity. -
Device 1 comprises a supportingstructure 2 fittable to the flush tank, e.g. by inserting atubular end portion 3 of supportingstructure 2 in fluidtight manner inside a drain hole in the flush tank; in which case, a bottom opening intubular portion 3 of supportingstructure 2 defines the drain hole of the flush tank, and is therefore indicated hereinafter as drain hole 4 for the sake of simplicity. -
Device 1 also comprises amain valve 5 for closing drain hole 4, and which is fitted to the bottom end of apipe 6 housed in sliding manner inside supportingstructure 2 and possibly formed in a number of pieces connected to one another. As in a known solution,pipe 6 also acts as an overflow pipe of the flush tank. - Supporting
structure 2 has openings 7 at the bottom, through which water flows from the flush tank to drain hole 4, and is fitted inside with a substantiallytoroidal vessel 8 having an inner flood chamber 9 defined by an inner lateral wall 13 and an outer lateral wall 14 ofvessel 8, which are substantially cylindrical and coaxial with each other. Inner lateral wall 13 defines, internally, aseat 15 in whichpipe 6 slides; andvessel 8 is open at the top and closed at the bottom by anannular bottom wall 16 in which is formed a through, e.g. annular,outflow opening 17 defined by anannular sealing edge 18. In one variation, a number of through outflow openings, e.g. arranged side by side circumferentially, are formed inbottom wall 16 ofvessel 8. - Whichever the case,
device 1 according to the invention comprises auxiliary valve means 19 for selectively opening and closing outflow opening 17 invessel 8. In the example shown, auxiliary valve means 19 comprise a substantiallyannular shutter member 20, which cooperates with sealingedge 18 to closeoutflow opening 17, and is connected integrally to apull member 21 slidable with respect tovessel 8. More specifically,pull member 21 comprises acylindrical body 22 and acontrol rod 23;cylindrical body 22 is coaxial with, located radially outwards of, and slides axially with respect to, inner lateral wall 13 ofvessel 8, and is fitted at the bottom end withshutter member 20; andcontrol rod 23 is fitted tocylindrical body 22 and extends vertically and parallel topipe 6 at the opposite end toshutter member 20. - A
float 25, e.g. a known substantially toroidal type, is housed freely inside flood chamber 9. -
Device 1 also comprises astop member 26 for arrestingfloat 25 and connected integrally tomain valve 5. In the example shown,stop member 26 is defined by acollar 28 fitted integrally aboutpipe 6 at a predetermined distance frommain valve 5, and from a peripheral edge of which a substantially truncated-cone-shapedlateral wall 29 extends downwards inside flood chamber 9 ofvessel 8.Collar 28 also has a through opening 30 in whichcontrol rod 23 ofpull member 21 is inserted in sliding manner; andcontrol rod 23 comprises, beneathcollar 28, astop portion 31 of a transverse (radial or circumferential) extension greater than opening 30, so as to interfere axially withcollar 28 and so push a correspondingfirst stop portion 32 of pipe 6 - defined, in the example shown, by a bottom surface of collar 28 - whenpull member 21 is raised with respect tovessel 8, as explained later on. -
Device 1 also comprises a connectingmember 35 carried bypull member 21 and which pushes a correspondingsecond stop portion 36 ofpipe 6 whenpull member 21 is lowered with respect tovessel 8, as explained later on. In the example shown,second stop portion 36 ofpipe 6 is defined by a top surface ofcollar 28 opposite thebottom surface 32. - More specifically, connecting
member 35 is an oscillating body connected in articulated manner, at apivot 37, to asupport 38 supportingpull member 21 and located abovestop member 26. Connectingmember 35 is substantially L-shaped, and comprises aportion 39 eccentric with respect topivot 37, and acatch 40 extending substantially perpendicularly with respect toeccentric portion 39. - Operation of
device 1 according to the invention will now be described with reference to Figures 1 to 3. - Figure 2 shows
device 1 in the rest position :main valve 5 is positioned closing drain hole 4;shutter member 20 closes outflow opening 17 ofvessel 8; open-topped vessel 8 is immersed in the water inside the flush tank to whichdevice 1 is fitted, so that flood chamber 9 ofvessel 8 is full of water;float 25 is retained inside flood chamber 9 bystop member 26; the total weight ofmain valve 5 andpipe 6 is greater than the buoyancy offloat 25; connectingmember 35 is in arest position 35a (Figure 2) in whicheccentric portion 39 rests on aperipheral edge 42 of supportingstructure 2, e.g. defined by a top edge ofvessel 8, which defines a retaining member for retaining connectingmember 35 inrest position 35a; andmain valve 5 and auxiliary valve means 19 are therefore disconnected. - Figure 3 shows operation of
device 1 when full discharge of the water in the flush tank is activated : by means of appropriate known actuating means, not shown for the sake of simplicity,pipe 6 andvalve 5 fitted to it are raised to open drain hole 4 and allow the water in the flush tank to flow out;shutter member 20, on the other hand, remains closing outflow opening 17 in vessel 8 (fixed); and connectingmember 35 remains inrest position 35a. - When the action of actuating means ceases,
pipe 6 andmain valve 5, the combined weight of which overcomes the buoyancy offloat 25, move down to close drain hole 4. The downward movement ofpipe 6, however, is slowed down byfloat 25, which is immersed inside flood chamber 9 full of water, and which exerts sufficient thrust to delay closure ofmain valve 5 until all the water in the flush tank has been discharged. - Figure 4 shows operation of
device 1 when partial discharge of the water in the flush tank is activated : in this case, the actuating means (not shown) act directly onpull member 21, which is raised together withshutter member 20 to detachshutter member 20 from sealingedge 18 of outflow opening 17 in vessel 8 (fixed). As it moves up, pullmember 21 also raisespipe 6, asstop portion 31 ofpull member 21 contacts and pushesstop portion 32 ofpipe 6, so that the same movement ofpull member 21 provides for opening both outflow opening 17 invessel 8 and drain hole 4 in the flush tank. - The upward movement of
pull member 21 also releases connectingmember 35 from retainingmember 42. That is, when connectingmember 35 is raised together withpull member 21,eccentric portion 39 is detached fromperipheral edge 42 ofvessel 8; and the weight ofeccentric portion 39 is such as to automatically rotate connectingmember 35 aboutpivot 37 untilcatch 40 comes to rest againstpipe 6, thus setting connectingmember 35 to the work position 35b shown in Figure 4. - When the action of actuating means ceases, both
pipe 6 withmain valve 5 and pullmember 21 withshutter member 20 move down to respectively close drain hole 4 in the flush tank and outflow opening 17 invessel 8. In work position 35b, connectingmember 35 reversibly connectsmain valve 5 and auxiliary valve means 19, bycatch 40 of connectingmember 35 pushing onsecond stop portion 36 ofpipe 6, i.e. the top surface ofcollar 28. - As such, pull
member 21 andshutter member 20 are also sustained, together withpipe 6, by the buoyancy offloat 25. In this case, however, sincevessel 8 is open at the bottom, the water inside flood chamber 9 flows out to reduce the thrust exerted byfloat 25, so that drain hole 4 is closed sooner bymain valve 5, when only a predetermined portion of the water in the flush tank has been discharged. - The amount of water discharged in partial-discharge mode depends on the section of outflow opening or openings 17 (if more than one is provided) and hence on the speed with which
pipe 6 andmain valve 5 close drain hole 4 in opposition to the thrust exerted byfloat 25, as well as, obviously, on the sizing offloat 25 and the other component parts ofdevice 1. - Clearly, changes may be made to the device as described herein without, however, departing from the scope of the accompanying Claims.
