Description

(54) DRIVE

I

The invention relates to hydraulic engineering and I can find application as a driver for hydraulic structures in months, where there is a difference in water levels. ; It is known a device that uses the pressure energy of a working fluid to infuse various machines and mechanisms, contains a chamber with nozzles for supply and from {water of a working fluid, a diaphragm with a rod: reciprocating and moving.

In the known device there is no siphon, in the pipeline of which a hole is made, which does not allow automatic reciprocating movement of the rod.

In the proposed device, the reciprocating movement of the rod is carried out due to the periodic operation of the siphon, in the pipeline of which there is a hole that connects its cavity with the atmosphere.

The drawing schematically shows the proposed device.

It contains a chamber 1 with connections 2

and 3 for supplying and discharging the working fluid. In the upper part of the chamber there is a valve 4, articulated with the stem 15 and hermetically sealed with a lid 6. A branch pipe 3 from the working fluid is connected to the siphon 7 IB of the pipeline which has a calibrated hole 8. immersed below the level of the lower reach .; The Patru ™ side 2 of the working fluid supply connects the upstream 9 of the structure with the chamber through the valve 1O,

The drive works as follows.

At OT1-FISHED valve 10, water from the upper pool enters chamber 1 via pipe i (wire 2.). The water entering the campha lifts diaphragm 4 with stem 5 to the upper; position and fills siphon 7, is displaced; air through hole 8, so as the lower end of the siphon is flooded below the level of the Lower Vief.

Water will flow through the siphon, under; Sasgoyempu1 through the opening 8. At the same time, the siphon will be equal to the flow of water flowing from the upstream and out of the chamber. With a full drawdown of the capacity of the camera 1 (di

a (in the lower position), the reaction of the siphon flow rate 7 decreases, the vacuum in the siphon increases, and the flow of air into the siphon through the opening 8 sharply increases, causing the vacuum to collapse and the siphon to come out of work. The cycle then automatically repeats.

Claims (1)

Claims of the Invention A drive comprising a chamber with a supply pipe for discharging working fluid to the top 42 22. Its part is fitted with a diaphragm articulated with a rod, characterized in that, in order to provide automatic reciprocating movement of the rod, it is provided with a siphon connected to the working outlet pipe, in which a hole is inserted in the pipe connecting its cavity with the atmosphere, and its output end is submerged under the level of JIAEOSTN.
