The invention can be used in automatic devices for intermittent fluid supply, for example in the field of plumbing.

An automatic device for intermittent fluid supply is known, comprising a self-charging fixed siphon connected to a container supplied by a constant-supply source (see ed. St. SSSD No. 409008, class F 04 F 10/00).

A siphon is known that contains a supply and drain bend of different lengths, the first of which is connected to a water source, and a curved drain pipe connected at one end to the top of the siphon (see UK taste 2198484, class F 04 F 10/00, 1988 )

This siphon is adopted as the prototype for the largest number of essential features.

A disadvantage of the known devices is the high level of water flow rate required for charging the siphon, and hence the flow rate. This level depends on the process of removing air from the area of the upper point of the siphon.

The purpose of the invention is to reduce water consumption during siphon charging.

To achieve the goal, the second end of the branch pipe is connected to the drain elbow from the side facing the delivery elbow.

Moreover, devices are known in which the removal of air from the cavity of the upper siphon zone is produced. forcibly, by a water-jet pump (see ed. St. USSR of Me 808709, class F 04 F 10/00). But such devices are impractical to use because of their complexity and bulkiness in metering devices, for example, in automatic

Claims (1)

The claims Siphon containing supply and drain bends of different lengths, the first of which is connected to a water source, and a curved outlet pipe, one end drain tanks, and others - of the same scale. In the device according to the invention, the role of a water-jet pump is played by a liquid overflowing into the outlet elbow of the siphon. The drawing shows the proposed device on the example of an automatic flushing plumbing tank. The tank contains a container 1, in the upper part of which a constant supply water source 2 is installed, in the form of a water supply system, and a self-charging fixed siphon 3 is connected to the lower part. The cavity 4 of the upper part of the siphon is connected by an air pipe 5 to the cavity 6 of the output bend of the siphon 3, and the pipe 5 is connected to the output bend through an opening on the bottom surface of the siphon 7 (side facing the supply elbow). The device operates as follows. Through the plumbing 2, water enters the tank 1 and fills it to overflow through a siphon. Then follows the siphon charging process, in which water overflows over the knee of the siphon, besides the fact that it carries some of the air with it and pushes it into the air pipe 5, it also sucks this air through this pipe and flows over the surface 7 , which goes into the hole of the tube 5, thereby accelerating the elimination of the meniscus. It is seen that when the siphon is charged, water overflowing through the knee of the siphon removes air from the upper zone of the siphon by suctioning it through an additionally provided duct, which means that the amount of water required for charging is reduced. connected to the upper point of the siphon, characterized in that, in order to reduce water consumption during charging of the siphon, the other end of the outlet pipe is connected to the drain elbow from the side facing the delivery elbow.
