The invention refers to a toilet cistern hydraulic inlet valve with a three-member assembly that involves a new constructional solution applied to the water supply system with the water passing through a small hole in the sealing membrane into the water level control chamber in the toilet cistern. The new constructional solution eliminates all deficiencies of the previous solutions as far as the sensitivity to the inlet water impurities is concerned. The toilet cistern hydraulic inlet valve with a three-member assembly referred to in this invention is provided with a three-member assembly (A) that consists of the base (1, 1'), the ball (2) and the cap (3). The two different ball (2) positions in the base (1, 1'), depending on the water pressure, provide for low flow at filling of the toilet cistern and for self-cleaning on completion of the filling operation.

Description

TOILET CISTERN INLET VALVE
The invention refers to a toilet cistern hydraulic inlet valve with a three- member assembly that involves a new constructional solution applied to the water supply system with the water passing through a small hole in the sealing membrane into the water level control chamber in the toilet cistern. The new constructional solution eliminates all deficiencies of the previous solutions as far as the sensitivity to the inlet water impurities is concerned. The invention has been classified as class E03D 1/32 of the International Patent Classification.
The technical problem successfully solved by the constructional solution in question is the construction of such inlet hydraulic valve that will provide for smooth operation of the toilet cistern in the way that the latter will be insensitive to various impurities in the water and will also provide for self-cleaning of those critical points that are exposed to blocking due to impurities or generation of water stone. With the existing versions of hydraulic inlet valves, the water supply is effected through the threaded connection piece containing a rough sieve that can stop the impurities of 0.3 mm. Therefrom the water passes centrally or along the edge of the valve housing into the central part of the valve where it possibly turns around against the housing wall and flows into the toilet cistern along the filler tube. During the water supply, a minor quantity of water flows through a small opening in the sealing membrane into the chamber behind it and thereafter through the opening at the back of the valve into the toilet cistern. As soon as the water level in the toilet cistern becomes as high as desired, the float stops the water supply via the float arm and the sealing, while behind the membrane a pressure is created to stop the water flow into the toilet cistern indirectly via the membrane sealing.
The main deficiency and/or problem arising at the operation of the above described hydraulic inlet valve lies in the small opening in the sealing membrane through which the water flows into the chamber. Due to the impurities present in the water and let through the rough sieve in the connection piece, and after some time of operation also due to the generation of water stone, such opening may get blocked and may prevent the operation of the valve. All the solutions known hitherto, e.g. the version with a special needle, one-end open plastic insert in the membrane, do not solve the imposed problem completely. The toilet cistern hydraulic inlet valve with a three-member assembly referred to in this invention is provided with a three-member assembly that consists of the base, the ball and the cap where two different ball positions, depending on the water pressure, provide for low flow at filling of the toilet cistern and self-cleaning on completion of the filling operation. The invention will be explained in detail on a concrete example and the pictures whereof
Figure 1 shows an axonometric view - partial section - of the toilet cistern hydraulic inlet valve with a three-member assembly, as referred to in this invention;
Figure 2 shows an axonometric view of a disassembled three- member assembly referred to in the first concrete example; Figure 2a shows the three-member assembly referred to in the first concrete example, as a side view of the cross- section; Figure 2b shows an axonometric top view of the cylindrically shaped part 1 b of the three-member assembly referred to in the first concrete example; Figure 3 shows an axonometric view of a disassembled three- member assembly referred to in the second concrete example; Figure 3a shows the three-member assembly referred to in the second concrete example, as a side view of the cross-section;
Figure 3b shows an axonometric top view of the cylindrically shaped part 1 b' of the three-member assembly referred to in the second concrete example.
In figure 1 , the toilet cistern hydraulic inlet valve with a three-member assembly is presented as a partial section. The figure reveals the position of the inserted three-member assembly A as a section. Figures 2, 2a and 2b show the three-member assembly A as referred to in the first concrete example as a disassembled axonometric view, as side view of the cross- section and as a axonometric top view of the cylindrically shaped part 1 b. The three-member assembly A referred to in the first concrete example consists of the base 1 , the ball 2 and the cap 3. The base 1 is provided in its lower part with a bigger cylindrical part 1a that passes to a narrower cylindrical part 1 b, with a protruded edge 1c and with two symmetrically protruded attachments 1d, 1 e. The cylindrically shaped part 1 b, terminated in the chamfered upper edge 1f, is provided with three symmetrical openings 4 in the way that even in case of the fitting ball 2 the water can pass through the part 1 b. The cap 3 is also provided with small openings 3a. Figures 3, 3a and 3b show the three-member assembly A as referred to in the second concrete example as a disassembled axonometric view, as side view of the cross-section and as a axonometric top view of the cylindrically shaped part 1 b'. The three-member assembly A referred to in the first concrete example consists of the base 1', the ball 2 and the cap 3. The base 1' is provided in its lower part with a bigger cylindrical part 1 a' that passes to a narrower cylindrical part 1 b', with a protruded edge 1 c' and with two symmetrically protruded attachments 1 d', 1 e'. The cylindrically shaped part 1 b', terminated in the chamfered upper edge 1f, is provided with three symmetrical openings 4' in the way that even in case of the fitting ball 2 the water can pass through the part 1 b'. The cap 3 is also provided with small openings 3a.
As evident from the above figures and the respective descriptions, the toilet cistern hydraulic inlet valve with a three-member assembly referred to in the invention is provided with an inserted three-member assembly, consisting of the base 1 ,1', of a glass or similar ball 2 and of the cap 3. The water supply is directed through the openings on the cap 3 and through the base 1 ,1' that is fixed in the centre of the membrane and shaped in the way that at the flow and/or at the filling a minimum water flow is possible even if the ball 2 fits snugly into the bed 1f,1f of the cylindrically shaped part 1 b, 1 b' of the base 1 ,1', while the water flow is possible through the openings 4,4' behind the membrane. The cap 3 prevents the ball 2 from being washed away and/or from falling out. On completion of the filling operation, due to the interrupted water pressure, the ball 2 leaves its bed and sets free a larger opening in the cylindrically shaped part 1 b, 1 b', whereby it enables self-cleaning of the critical points in the inlet valve.
The toilet cistern hydraulic inlet valve with a three-member assembly, such as referred to in this invention with reference to the two concrete examples, successfully solves the imposed technical problem that used to be a deficiency of toilet cistern hydraulic inlet valves.
