нем осевой канал 8, сообщающий полость фильтрующей камеры 5 с каналами 7. Камера 5 снабжена фильтром 9. В канале 8 установлен обратный клапан 10 дл  предотвращени  попадани  твердых частиц в камеру 5. При открытом положении запорного органа 2 поршень 6 находитс  в верхнем положении , и рабоча  среда через фильтр 9 заполн ет камеру 5. При закрытии поршень 6, перемеща сь в камере 5 вниз, выдавливает из нее отфильтрованную жидкость, часть которой поступает по каналам 8 и 7 к уплотнительной поверхности седла, а друга  часть проходит через фильтр 9, очища  его. Формула изобретени  1. Запорный узел клапана, запорный орган которого выполнен с каналами дл  подвода отфильтрованной жидкости к уцлотнительной поверхности седла, отличающийс  тем, что, с целью автоматической подачи отфильтрованной жидкости к уплотнительной поверхности при закрытии клапана, запорный орган снабжен поршнем с осевым каналом, а в проходном отверстии седла выполнена фильтрующа  камера, взаимодействующа  с поршнем при срабатывании устройства. 2. Запорный узел клапана по п. 1, отличающийс  тем, что, с целью предотвращени  попадани  твердых частиц в фильтрующую камеру, в канале поршн  установлен обратный клапан. Источники информации, прин тые во внимание при экспертизе: 1.Патент США № 2912003, кл. 137-547, 1959. There is an axial channel 8 connecting the cavity of the filter chamber 5 with the channels 7. The chamber 5 is equipped with a filter 9. In the channel 8 a check valve 10 is installed to prevent solid particles from entering the chamber 5. When the closure member 2 is open, the piston 6 is in the upper position, and The working medium through the filter 9 fills chamber 5. When closed, the piston 6, moving downwards in chamber 5, squeezes the filtered liquid out of it, part of which flows through channels 8 and 7 to the sealing surface of the seat, and the other part passes through filter 9, clearing it. Claim 1. Valve valve assembly, whose shut-off element is made with channels for supplying filtered fluid to the seating surface of the seat, characterized in that, in order to automatically feed the filtered fluid to the sealing surface when the valve closes, the locking member is provided with a piston with an axial channel, The filter chamber interacting with the piston when the device is triggered is made in the bore of the seat. 2. Valve valve assembly according to claim 1, characterized in that, in order to prevent solid particles from entering the filter chamber, a check valve is installed in the piston channel.
