At this time, the water in the working sprinkler is carried out through the pivot knee 2. The pivot knee 3 passes over the partition structure 11, shoulder 40 by the pressure plate closes contact 7. Current, passage through the coil 30, closes contacts 28 and the block contacts 32 of the reversing magnetic starter 26. The electric motor 23 is turned on, but with rotation in the opposite direction. The knee 3 is lowered to a vertical position, but the operation of the electric motor 23 and the unwinding of the cable 22 continues until the check valve 4 is fully opened, which occurs under the action of a vacuum in the suction line LI 1. After this, the two shoulders lever 18 presses the button on the normally closed button contact 9, whereby the motor 23 is turned off. Water is now taken in through both bends 2 and 3. When the suction line I moves along the canal in the opposite direction and the bend 3 meets the partition structure 11, its passage through the structure occurs in the same order as indicated. In order to make the transition through the blocking structure of the knee 2, it has the necessary elements for this, called for the knee 3. The buoyancy of the suction line 1 is ensured by two floats 14 fixed to the ends of the bends. From plant and other floating debris, water is cleaned using filter grids 15.

The accidental simultaneous switching on of normally open three-phase contacts 27 and 28 can be warned on each knee by cross-blocking normally open contacts 6 and 7 and normally closed 8 and 9. If such switching-on occurs, protection is provided by fuses 36. Motor 23 is protected overloads are provided by thermal relays 33 and 34 installed in the housing of the reversing magnetic actuator 26. Thermal relays disconnect from the electrical line 10 two phases of the drive of the engine 23. On e phase is performed by pressing the return 35 installed in the body 26.
