Description

Title of the invention: Delayed water supply device Technical field of the invention

[0001] The present invention relates to a device for delaying the water supply to a toilet. Prior art

[0002] Typically, a toilet flush includes a tank, a water inlet for filling the tank, and a water outlet valve for evacuating water for flushing.

[0003] A flushing device is installed in the tank and comprises a float connected to a tap which allows the water inlet to be closed when the high level in the tank is reached.

[0004] When the flush is activated, the water level drops, the float moves down and opens the valve. The tank fills again until the water level is sufficient for the float to close the valve.

[0005] The disadvantage of this type of flush is that, as soon as the flush begins, the float descends and the valve opens. The inlet valve and the outlet valve are therefore open simultaneously during the flushing time.

[0006] The quantity of water used during this time is therefore greater than that required to flush the toilet and the additional water is consequently wasted unnecessarily. Description of the embodiments

[0007] A problem that the present invention proposes to solve is to provide a device making it possible to avoid the aforementioned drawbacks. In particular, the object of the invention is to provide a device making it possible to reduce or cancel the time during which the inlet tap and the outlet valve of the toilet tank are open simultaneously, in order to avoid wasting water.

[0008] The solution proposed by the invention is a toilet device intended to be arranged upstream of the inlet valve of the flush tank (see figure 1). Said device being of cylindrical shape with a male thread and a female thread at each end (see [Fig.2]).

[0009] This is composed of the following elements (see sectional view [Fig.3]):

[0010] 1: Threaded body

[0011] 2: Threaded inlet fitting

[0012] 3: Threaded outlet connection

[0013] 4: Perforated washer

[0014] 5: Calibrated valve

[0015] 6: Threaded sleeve

[0016] 7: Valve

[0017] 8: Valve seal

[0018] 9: Piston

[0019] 10: Piston spring

[0020] 11: Valve spring

[0021] 12: Output O-ring

[0022] 13: Inlet O-ring

[0023] 14: Internal stop circlips

[0024] The operation of the present invention is divided into several stages:

[0025] At rest, water is present throughout the system and the springs (10) and (11) push the piston (9) and the valve (7) back to the stop. This exerts a force from the valve seal (8) on the holes in the threaded sleeve (6), which closes the main water supply circuit.

[0026] When the flush is activated, the toilet inlet valve opens, the downstream water is released and the system begins its operation (see [Fig.4]).

[0027] First, the water passes through a series of washers perforated with several small orifices (4), which makes it possible to reduce the speed of the water introduced into the system.

[0028] Then, the water passes through a calibrated valve (5) which reduces the flow rate to a very small quantity of water.

[0029] The piston (9) held by the piston spring (10) is then slowly pushed by the small quantity of water. It will thus take several seconds for the piston (9) to come into contact with the valve (7).

[0030] Once the piston (9) is in the stop position, it exerts its force on the valve (7) and compresses the valve retaining spring (11). This has the effect of releasing the contact between the valve seal (8) and the orifices of the threaded sleeve (6) and thus opening the main water circuit and supplying the toilet tank with water.

[0031] As soon as the tank is filled, the float closes the toilet inlet valve and the entire system returns to its initial position.

[0032] The few seconds taken by the piston (9) to open the device make it possible to delay the supply of water to the toilet, which avoids wasting several decilitres of water with each flush.
