FR2656642A1 - AUTOMATIC RETURN SYSTEM IN THE INITIAL STATUS OF THE AIR CHAMBER OF HYDROPNEUMATIC DISCHARGE DEVICES FOR WATER-CLOSET RESERVOIR. - Google Patents

Abstract

Automatic system of return to the initial state of the air chamber of hydropneumatic discharge devices for water-closet tank. Its purpose is to facilitate the return to the initial position of the valve, thus ensuring its rapid closure, immediately after discharge. The system uses the water inlet to the tank, after it has passed through the tap (1), to inject air through the feed water flow and to bring it into the tank in which it is released, and in which it rises along the interstices between the float (9) and the bell (5), to accumulate in the latter by returning the float (9) to their closed position and the valve (10), which results in instant filling of the reservoir and the possibility of immediately using the discharge device.

Description

OBJECT OF THE INVENTION

  The object of the invention relates to a system for returning to the initial state L of the air chamber in the discharge devices.

of water closet tank.

  Its characteristics have been studied to use the water inlet to the tank as a means of air injection, to ensure the return to the initial state of the hydropneumatic chamber, thus guaranteeing the rapid closing of the shutter. or

Lapet.

ANTECEDENTS OF THE INVENTION

  Among the many types of discharge devices

  water-closet tank are known.

  pneumatic, that is to say those that cause the discharge When occurs, in the upper part of the c Loche which they are equipped, a depression that releases an internal l Lotteur and rises up to the party high, drawing with Him the c Lapet who

  Thus releases the mouth of discharge of the tank.

  This kind of discharge device poses the problem of operation which is that, when the control is actuated, at a point for which the level of the water that exists at that moment is not sufficient for the If the Lottor gives rise to a total discharge, a small discharge occurs which causes the input rate to be equal to the output rate and, therefore, that

The system does not work.

  The initiative consisted in injecting pressurized air into the c Loche.

DESCRIPTION OF THE INVENTION

  To bring a solution to this problem, it is proposed, in accordance with the invention, an automatic system for instantaneous return to the initial state L of the air chamber, in

  Hydropneumatic water tank discharge devices

c Loset.

  The system consists of an air injection through the feed water flow of the tank and to do it

arrive at the bell.

  For this purpose, one or more capillary ducts have been provided in the feed group so that the injection of air is produced by the water flow itself. These capillary ducts may be constituted by external axial grooves, which are partially covered by the

  flexible conduit that brings water to the tank.

  This air is channeled into the bell of the discharge device, through a conduit which is tangential to the inner wall of the bell and inside thereof, so that the air injected by the flow of water is released inside the bell and rises along the interstices between

  the float and the bell, to accumulate in the latter.

  This allows the return to the initial state of the air chamber of the bell, because this air injection that accumulates there creates a pressure on the float and on the valve, which guarantees the closure, giving rise to the immediate filling of the tank and the possibility of using the discharge device again

  DESCRIPTION OF A PREFERRED EMBODIMENT

  As shown in the drawings in question, the system comprises, at the outlet 1 of the tank filling water supply valve 2, external capillary ducts 3 which are partially covered by the flexible duct 4 which is connected to the upper part. of the bell 5 from which the end 6 of the filling tube 7 extends, which is tangent to the wall of the bell and inside thereof in the axial position. This tube 7 ends

  above the windows 8 discharge The bell.

  The bell is occupied by a float 9 integral with the valve 10 which closes the discharge pipe of the tank (not shown) The upper part 11 of the c Loche constitutes the hydropneumatic chamber It has a communication 12 with the outside and e L is Linked to a vacuum pusher by means of

of a flexible tube 13.

  The function exerted by the system begins when one acts on the vacuum device, and the pressure of the air disappears in the upper chamber 11 of the bell 5, escaping through the tube 13, so that the float 9 rises, being aided by the water contained in the tank, to occupy the chamber 11, carrying with it the valve 10 which opens the mouth of the cistern discharge. The supply valve 2 opens immediately and the water enters through the outlet 1 and continues along the flexible tube 4 until reaching the end 6 of the filling tube 7

  tangent to the inner wall of the bell, in axial position.

  During its passage through the external capillary duct 3, the water sucks bubbles of ambient air and injects them into the interior of the bell, the filling tube 7 being interrupted for this purpose over discharge windows 15

of the bell.

  The air passes through the interstices between the float 9 and the bell 5 to occupy the chamber 11 and accumulate there, which gives rise immediately to the descent of the float 9 and the valve

to close the discharge mouth.

  The system can be applied to any hydropneumatic discharge device utilizing both faucets

  Side and vertical feeders.

Claims (3)

  1 automatic system for returning to the initial state of the air chamber of the hydropneumatic discharge devices for a water closet tank, characterized in that it consists in producing an injection of air into the tap (1) through the flow of feed water from the tank and to the bell (5) to obtain an air pressure sufficient to ensure the return of the float (9) and the valve (10) to the position of closing.   2 System according to the preceding claim, characterized in that the injection of air through the stream of water is obtained at the outlet of the supply valve (1) by one or more capillary ducts (3) constituted by grooves axially, which are partially covered by the   flexible (4) which brings water to the tank.   3 System according to either of claims 1 and   2, characterized in that the water inlet pipe (7) to the tank is installed inside the hydropneumatic bell which contains the float (9) and the valve (10), tangential to its wall and in position axial, its extension being limited at a point above the position of the discharge windows (8), so that the air injected through the stream of water rises by itself through the interstices between the float (9) and the bell (5), to accumulate in the upper part (11) of the latter, in   closing the flap (10).
