Устройство работает следующим образом . При движении устройства по полю рабоча  жидкость из бака 1 через трубопровод 2 насосом 3 подаетс  в нагнетательнь трубопровод 5 и при открытом ударном клапане 8 через сливной трубопровод 9 вы ливаетс  в бак. При разгоне потока жидкости до критической скорости ударный кла пан 8 резко закрьшаетс , вследствие чего в напорном трубопроводе возникает гидравлический удар. Под действием гидравлического удара напорньй клапан 6 открьшаетс  и жидкость под высоким давлением выбрасываетс  через насадок 7 в почву. Одновременно возникает возвратна  удар на  волна, котора  распростран етс  под несколько меньшим давлением в обратную сторону. При подходе возвратной ударной 34 волны к эжектору 13 часть жидкости по кольцевому зазору 16 устремл етс  в кольцевую камеру 17, в результате чего происходит демпфирование потока жидкости, иэнерги  возвратной ударной волны резко гаситс . Формула изобретени  Устройство дл  внутрипочвенного внесени  жидких  дохимикатов или удобрений по авт,св, № 328859, отличающеес   тем, что, с целью повышени  эксплуатационной надежности устройства посредством уменьшени  воздействи  возвратной ударной волны на насос, в напорной магистрали установлен по крайней мере один эжектор , заключенньш в камеру, закрепленную на напорной магистрали.The device works as follows. When the device moves across the field, the working fluid from the tank 1 through the pipeline 2 is pumped into the discharge pipe 5 by the pump 3, and when the shock valve 8 is open, the drain pipe 9 flows into the tank. When the fluid flow accelerates to a critical speed, the impact valve 8 is sharply closed, as a result of which a hydraulic shock occurs in the pressure pipeline. Under the action of a hydraulic shock, the downstream valve 6 opens and the high-pressure liquid is thrown through the nozzles 7 into the soil. At the same time, there is a reciprocal impact on the wave, which propagates under a somewhat lower pressure in the opposite direction. When a return shock 34 approaches the ejector 13, part of the liquid rushes through the annular gap 16 into the annular chamber 17, as a result of which the fluid flow is damped, and the energy of the return shock wave is sharply quenched. The invention The device for the subsurface application of liquid chemicals or fertilizers according to the author, no. 328859, characterized in that, in order to increase the operational reliability of the device by reducing the impact of the return shock wave on the pump, at least one ejector is installed in camera mounted on the pressure line.
