Definitions
- ABSTRACT Flushing apparatus comprising a cistern mounted between the feed-pipe and the flush-pipe and containing a device with an entry and air escape valve as well as a valve connected with a seating formed at the entry to the flush-pipe and subject to the hydrostatic pressure of the water contained in a chamber communicating with the said pipe through a valve governed by the handle operating the flush, wherein the valve (connected with the seating formed at the entry to the flush-pipe) is suspended from a flexible diaphragm forming one of the walls of said chamber communicating with the cistern through a small aperture provided in another section of the wall.
- the present invention relates to a flushing system of the type comprised of a cistern set between the feedpipe for water under pressure and the flush-pipe and containing in its upper part an entry and air escape valve, governed by the level of refill in the cistern, and, in its lower part, a valve acting in conjunction with a seating formed at the entry to the flush-pipe and subject to the effect of the hydrostatic pressure of the water contained in a chamber, the upper part of which communicates with the flush-pipe through a valve governed by the handle operating the flush.
- the said valve is formed by a piston of plastic material for example, sliding in the said chamber executed in the form ofa cylinder communicating through a side-opening with the cistern so that the water may circulate round the latter and fill the whole of the said chamber situated above the piston, in order to keep the semi-spherical lower part forming the valve in contact with the seating affixed at the entry to the flush-pipe.
- piston and cylinder have to be made with great precision, since free play is essential to the smooth functioning of the apparatus.
- the invention proposes, in a flushing system of the above-mentioned type, to suspend the valve from a flexible diaphragm, elastic for preference, forming one of the walls of the lower chamber which communicates with the cistern through a small aperture arranged in another part of the wall of the said chamber or of the outlet pipe.
- the elastic diaphragm forms the lower part of the said lower chamber, the upper part of which is formed by a cupel bolted to the diaphragm, the outer face of the diaphragm bearing a spherical element constituting the said valve.
- the lower part at least of the said chamber is formed by an elastic bellows, one end of which is fixed to the side wall of the chamber and the other to the semi-spherical end of a cylindrical body introduced into the said chamber.
- the valve may, with advantage, be mounted on the flexible diaphragm or on the bellows by means of a groove in the diaphragm or bellows which fits over a peripheral flange on the body of the valve, the bellows being affixed to the said chamber by the same type of join.
- FIG. 1 is a view in section with partial cut-away of a first embodiment of a flushing system according to the invention.
- FIG. 2 is a similar view of a second embodiment.
- FIG. 3 is a view in section of the lower part of the said chamber, showing the method by which the valve is attached to the elastic bellows.
- reference No. 1 indicates the cistern made of an outer casing of enamelled plating and having a possible inner casing of anti-corrosive material, preferably polyethylene, not shown.
- the lower part of the cistern is enclosed between two base-plates 2, 3, water-tight and held by nuts.
- the baseplates 2, 3 and the bottom of the cistern have a hole in their centre providing an outlet indicated by the general reference 5, the base-plate 3 being furnished with a threaded section 6 to connect with the flush-pipe, not shown, which extends below the outlet 5.
- the outlet 5 will be referred to as the flush-pipe.
- the head 9 of a rod 10 moves against the action of a compression spring 8; the head of the rod bears on the handle operating the flush ll jointed at 12 to a yoke 13 carried by the base-plate 3.
- the rod 10 passes through an aperture 14 in the wall of the flush-pipe 5 and carries a rubber joint 15 which forms a valve and is situated in a cavity 16 in the base-plate 3.
- the upper opening of the flush-pipe 5 carries a seating 17 for a spherical valve 18 attached, by means not shown, to the base 19 provided on the outer face of an elastic diaphragm 20 forming a lower chamber 21 with a rigid cupel 22 to which it is fixed so as to be watertight by means of bolts 23 passing through cross-braces 24 and screwing into the base-plate 2.
- the rigid cupel 22 is provided with a small opening 25 through which the lower chamber 2] communicates with the cistern 1 and an outlet pipe 26 from its periphery opens freely at 27 into the cavity 16, communication between the cavity 16 and the flush-pipe 5 being controlled by the valve 15.
- the water feed pipe 28 is attached by means not shown to the source of water under pressure and surmounted by an anti-return valve 29.
- a hole 30 through which passes the hollow rod 31 bearing a threaded flange 32; the bottom of the rod 33 has an aperture 34 in it and the said hollow rod is held in place by means of an interposed joint 35 and a nut 36 screwed to the part of the hollow rod coming out of the cistern 1.
- a bell 37 provided with a horizontal dividing wall 38 with a hole 39 in it and having on its lower face a joint 40.
- the bell is thus divided into a first chamber 41 in which is a freemoving first spherical ball 42 with a needle 43, and a second chamber 44 in which is a free-moving second spherical ball 45 surmounted by a needle 46, the said second ball being prevented from moving out of the second chamber 44 by an under-pin 47.
- a pipe 48 leads from the first chamber 41 to the flush-pipe 5 at 49.
- the feed-pipe 28 is connected to the source of water under pressure; the water enters the cistern 1 passing through the anti-return valve 29 and begins to fill the cistern 1, the water at the same time filling the chamber 21, passing through the hole 25 in the upper part of the rigid wall 22 of the said chamber.
- the water from the cistern will fill the upper chamber 41, raising the ball 42 so that the needle 43 of ball 42 enters the aperture 34 and the outlet 31 is blocked by the said ball 42 coming to rest against its seating 33.
- the water which continues to pass through the upper chamber 41 then flows away through the deviation 48 and into the flush-pipe 5 through the opening 49.
- the water contained in the lower chamber 21 is able to flow away through the pipe 26, the cavity or intermediate chamber 16, and the aperture 14, into the flush-pipe 5.
- the pressure exerted through the flexible diaphragm on the spherical valve 18 diminishes; the said valve 18 is raised from its seating 17 and the water contained in the cistern 1 is able to pass directly into the flush-pipe 5 until the cistern l'is completely emptied.
- FIG. 2 The embodiment of the flushing system according to FIG. 2 is essentially identical to that of FIG. 1, except for the formation of the lower chamber.
- two or more cross-brace bolts 23-24 screwed into the upper part of the base-plate 2, serve to hold in place a plate 51 with a central aperture 52.
- the chamber underlying it formed by a cylindrical wall 56, communicates freely with a pipe 50 which is the equivalent of the pipe 26 in the embodiment according to FIG. 1, the said pipe or conduit 50 communicating freely with the intermediate chamber 16.
- a bellows 53 of elastic material such as rubber or plastic is attached to the lower part of the cylindrical wall 56 to the lower part of the cylindrical wall 56.
- a bellows 53 of elastic material such as rubber or plastic, the bellows in question ending in a semi-spherical head 57.
- a piston 55 with a semi-spherical head is engaged in the bellows, its upper part sliding in the spherical wall 56.
- the semi-spherical part 57 acts in conjunction with the valve seating 17 at the upper end of the flush-pipe 5.
- the cylindrical wall 56 is provided with a peripheral groove into which fits a ring-flange 58 carried by the upper part of the bellows 53, while the lower part of the bellows carries a circular flange 59 which fits into a corresponding groove in the lower part of the piston 55, the semi-spherical part of which is indicated by the reference No. 57.
