Abstract
The invention relates to a faucet for filling tanks known as silent and/or fast-closing faucets. The faucet comprises a basic structure and functionalities such as those disclosed in Patent 9400095. The device assembly controlling opening and closing of the faucet has important improvements in comparison with other conventional faucets and in comparison with the above-mentioned patent. The faucet also includes a lever system connecting the float and the piston acting upon the opening and closing device. In additional, improvement deals with the telescopic structure of the fluid outlet tubes to the tank in order to regulate the height thereof depending on the depth of the tank so that the fluid is always discharged into the water with the aim of preventing noises.
Claims34
A faucet for filling tanks, of the type comprising a casing that includes an inlet duct and an outlet duct, a tubular piece being secured to that casing by means of an exterior locking or fastening nut, an internal cavity being formed between the casing and the tubular piece in which two facing elastic rubber pieces, a forward elastic rubber piece and a rear elastic rubber piece, are housed and associated by linking means;
- an intermediate chamber being formed between the two rubber pieces, said chamber being connected in a first direction to a rear chamber via an opening in the rear rubber piece, said rear chamber having a constriction where an intermediate body provided with a longitudinal opening is fitted, said intermediate body being in contact with a piston also housed in a part of said constriction made in the tubular piece, an opening and closing mechanism associated to a float acting on a piston by means of a vertical element, it being provided for that the intermediate chamber be connected in a second direction to an inlet duct of a water network via a narrow opening made in the forward rubber piece;
- there being a larger duct concentric to said inlet duct for connecting the inlet duct with the tank via the outlet duct, the larger duct and the inlet duct being separated by means of an intermediate partition, the forward rubber piece being able to rest on a free edge of the intermediate partition, the forward rubber piece including a central ledge that extends outwards;
- the rear chamber being connected outside by means of a drainage;
- the faucet being characterised in that it includes:
- a compensating spring (25) housed in a rear chamber (10) and which presses against a rear rubber piece (7), while an opposite end of the spring rests on an annular channel (36) of a tubular piece (5);
- a non-return mechanism inserted in a diversion (48, 67) which connects with an outlet duct (3), and thereby reduces the development of hums and noises when water flows through the outlet duct (3);
- at least two telescopic pipes (41,42), the larger of which (41) is connected to the outlet duct (3) to be adapted to the tank depth.
