Description

IMPERIAL

The invention relates to such flushing devices, their water outlet with one at the bottom with inlet openings for the water provided bell is in communication and when the cistern is full through the outlet the overpressure from the air bell when the cistern was filled in action be set. The invention consists in the fact that the inside of the air bell ίο Mouth of the drain line as a seat for a freely movable valve body in the bell is designed, whereby the reliability of the flushing devices is increased because the Air compressed in the bell when the float leaks or when the water overflows through the siphon pipe not entrained and thereby the flushing device can be made ineffective.

In the drawing, the flushing device according to the invention is in two exemplary embodiments shown.

Fig. Ι shows one embodiment in longitudinal section.

Fig. 2 is a section and
3 is a view of the air bell.

Fig. 4 is a view of the ring used to secure the air bell.

Fig. 5 shows the other embodiment in longitudinal section.

Fig. 6 shows in section the push button for the air release line.

The nozzle 4 is on the bottom of the container 1

for connecting, the flush pipe attached.

At this nozzle 4 closes (Fig. 1) in Inside the container 1 a U-shaped bent and with its legs the bottom of the container 1 facing tube 5. Of the Nozzle 4 is also provided with a lateral branch 6, which on the one hand to a Ring 7 for attachment of the air bell 8 and on the other hand to the seat 9 for the in the Air bell 8 arranged valve 10 is formed. The ring 7 (Fig. 2) is on two or more areas with bulges 11 Insertion of the lugs 12 located on the bell 8 and also almost on his entire circumference with slots 13 and the air bell 8 at its lower end Recesses 14 are provided so as to prevent liquid from escaping from the container 1 in the bell 8 to allow. The attachment of the air bell 8 to the ring 7 of the Junction 6 takes place through the noses 12, after inserting the bell 8 into the ring 7 by turning it under the over The bar left standing in the recesses 13 and so the bell 8 with the ring 7 jam (Fig. 1 to 4).

The valve body 10 is at its bottom with a wart 15 made of flexible material, made of rubber, for example, with which the valve sits on its seat 9.

A line 16 leads from the air bell 8 to a device by means of which the overpressure is drained from the bell 8. This device is that in Fig. 6 in section / push button shown; it consists of the two-legged housing 17, 18; of the the upper (17), to which the line 16 is connected, is used for the two legs

Claims (3)

Receipt of the valve 20 and the other, lateral leg 18. for recording .des. 'Pusher: -21. "This 1" is usually held to the outside by the spring 22, while the valve 20 in the leg 17 is pressed onto its seat by the spring 23, thus preventing air from flowing out of the line 16. If the air is to flow out, is the pusher 21 is pressed inwards; the cone 24 of the pusher now comes against the valve stem 25, as a result of which the valve 20 is raised 17. In the second embodiment shown in Fig. 5, the drain or siphon valve is formed at the same time as the drain pipe The mouth of the connection 4 for the connection of the flushing pipe is formed to the seat 9 for the siphon valve and with the ring 7 for receiving the air bell 8. The siphon valve, unlike the valve 10 (of FIG. 1), consists of three parts arranged concentrically to one another, the outer cylinder 26 with which the si ch leads the valve in the air bell 8, and the inner cylinder 27, in and on which the cylinder 28, which at the same time forms the actual valve and the drain pipe, is arranged. This cylinder is .near its lower end with an elastic covering 15 with which it sits on the seat 9. The formation of the ring 7 and the bell 8 and the connection of both is the same as in Fig. I. The mode of operation of the device is as follows: Assuming that the container 1 is filled, the various parts assume the position shown in FIGS. 1, 5 and 6. If rinsing is to be carried out, the trigger 21 of the button (FIG. 6) is pressed inwards, the valve 20 is raised and the chamber 17 and the line 16 are connected to the outside air. As a result, the overpressure created in the air bell 8 when the cistern 1 is filled escapes; the valve 10, 15 of FIG. 1 or 26, 27, 28, 15 of FIG. 5 rises under the action of the liquid pressure from its seat 9, and it occurs. Liquid via this through the channel 6 (Fig. 1) or directly (Fig. 5) into the nozzle 4 and the flushing pipe connected in this (Fig. 1). 55. The liquid passing through the valve seat 9 is the. in the siphon pipe 5 of Fig. 1 or in the liquid standing between the cylinders 27 and 28 of Fig. 5 is sucked through the openings 29 after the drainage nozzle 4 and thereby the suction of the liquid from the container 1 through the pipe 5 (Fig. 1 .) or 28 (Fig. 5) initiated due to the siphon effect. Now the valve 10, 15 (Fig. 1) or 26, 27, 28, 15 (Fig. 5) falls back onto its seat 9 under the sucking effect of the liquid falling in the flushing pipe, and the liquid continues to run out through the Pipe 5 (Fig. 1) or 28 (Fig. 5) until the water level in the cistern 1 has dropped. The button 21 only needs to be pressed until liquid flows over the seat 9, which initiates flushing. The device shown in Fig. 1 can also be converted so that it only rinses as long as the button 21 (Fig. 6) is pressed, namely in that. the one attached to the bend of the tube 5. Vent screw 30 is opened. The siphon pipe 5 then becomes an ordinary overflow pipe. If, after removal of the screw 30 from the pipe 5, the flushing is initiated in the manner indicated above, the liquid which passes through the seat of the valve 10, 15 through the channel 6 to the drain connection 4 and the drain pipe does not suck in any liquid through the pipe 5, since the rising of liquid in the leg of the elbow pipe 5 opening into the cistern is prevented by the opening exposed after unscrewing the go screw 30. Only liquid can therefore escape from the cistern through the channel 6; but only as long as the air bell 8 is brought into connection with the outside air by means of the line 16 and the push button. If the button is released, the valve 10, 15 falls back on its seat, supported by the suction effect of the liquid flowing through the channel 6, the nozzle 4 and the flush pipe. Then no more liquid can flow out of the cistern. Godfather τ-An Proverbs: 1.
