Abstract

The invention makes it possible to increase the efficiency of the wheel in case of small footpaths. In the cavity of the casing I, a rotor 4 is installed with working chambers divided by partitions into external and internal airtight cavities 5,6. Cavity 5 communicates with the cavity of the casing, and the cavity 6 in pairs are interconnected by means of tubes 7 and filled with a liquid whose density is different from the density of the working medium. The working chambers are made in the form of cylinders (C) 8, the neighboring of which are located at a right angle to each other. Each partition is made in the form of a piston 9 installed in C 8. The piston on the side of the external cavity is provided with an elastic sheath 10 fixed to its wall. C 8 is equipped with piston stroke limiters 11. Water presses on the pistons and moves them synchronously with the pistons of the neighboring C 8, and the liquid filling the tube 7 then goes to the opposite part of the rotor and presses on the pistons of the neighboring C 8, which push the water from C 8 to the outlet conduit 3. As a result, there is an increase in the total moment of forces acting on the wheel. 1 il. (L

The invention relates to hydraulic engineering and can be used in water wheels operating at low heads.

The purpose of the invention is to improve efficiency at low heads.

The drawing schematically shows a water wheel.

The water wheel contains a casing 1 with inlet and outlet conduits 2 and 3 and a rotor 4 installed in the cavity of the casing with working chambers divided by partitions into external and internal hermetic cavities 5 and 6, the first of which are connected to the cavity of the casing 1, and the second - connected in pairs by means of tubes 7 and filled with liquid c. density other than that of the working medium, the working chambers made in the form of cylinders 8, the adjacent of which are located at a right angle to each other, and each partition is in the form of a wall 9 installed in the cylinder 8 and provided with an external cavity fixed on its wall by an elastic partition 10, and the cylinders are provided with piston stroke stops 11.

The water wheel works as follows.

Water is supplied to the supply water 2, through which it enters Jozhukh 1 and enters the external cavity 5 of the cylinders 8 of the rotor 4 and causes its rotation. The water presses on the pistons 9 (which it is advisable to carry out massive) and moves them synchronously with

the adjacent cylinders 8, and the fluid filling the tubes 7, then retracts into the opposite part of the rotor 4 and presses on the pistons of the adjacent cylinders 8, which reach the restrictors of stroke II, push the water out of the cylinders to the discharge conduit 3, as a result an increase in the total torque acting on the water wheel.

Such an embodiment of the water wheel will increase its efficiency at low pressures.
