Изобретение относитс  к арматуростроению и может быть использовано в гидрав7шче .ских и пневматических системах. Известен винтовой регулируемый дроссел с установленным в корпусе штоком, на поверхности которого выполнена винтова  канавка переменного сечени . С целью расширени  диапазона регулировани  в корпусе предлагаемого дроссел  вы полнены винтовые канавки с посто нным ша гом, совпадающим с одним из шагов винтовой канавки штока. Кроме того, шток подпружинен , и усилие пружины направлено по направлению движени  среды. На фиг. 1 показан общий вид предложенного винтового дроссел ; на фиг. 2 - зона дросселировани . В корпусе 1 с винтовой канавкой 2 с посто нным шагом установлен шток 3, на поверхности которого выполнена винтова  канавка 4 переменного сечени . Винтова  нарезка корпуса и штока образуют ьинтовой дросселирующий канал переменного сечени . Шток 3 подпружинен пружиной 5, и усилив пружины направлено по направлению движени  среды. Дроссель работает следующим образом . При вращении шТок 3 перемешаетс  вдоль оси относительно корпуса 1, в результате чего измен етс  длина и сечение рующего канала. Пружина 5 поджимает шток к корпусу по контактирующим боковым винтовым поверхност м. Формула изобретен и;   1.Винтовой регулируемый дроссель с установленным в ксфпусе штоком, наг поверхности которого выполнена винтова  канавка переменного сечени , отличающийс  тем, что, с иелью увеличени  диапазона регулирован 1Я, в BunoJVi нены винтовые канавки с посто нным шагом , совпадающим с одним из шагов винтовой канавки штока. The invention relates to valves and can be used in hydraulic and pneumatic systems. Known screw adjustable throttle with a rod installed in the housing, on the surface of which a screw groove of variable cross section is made. In order to expand the range of regulation, helical grooves with constant pitch, coinciding with one of the pitch of the helical groove of the rod, are made in the housing of the proposed throttle. In addition, the stem is spring-loaded, and the spring force is directed in the direction of movement of the medium. FIG. 1 shows a general view of the proposed screw throttle; in fig. 2 - throttling zone. In case 1 with a screw groove 2 with a constant pitch, a rod 3 is installed, on the surface of which a screw groove 4 of variable cross section is made. The screw thread of the body and the rod forms a pin throttling channel of variable cross section. The rod 3 is spring-loaded by the spring 5, and the spring is strengthened in the direction of the medium movement. The choke works as follows. During the rotation, the rod 3 will move along the axis relative to the housing 1, as a result of which the length and cross-section of the ditch channel changes. Spring 5 presses the stem to the body along the contacting side screw surfaces. The formula was invented and; 1. Screw adjustable throttle with a stem installed in the xpfus, with a screw groove of variable cross section, which is characterized by the fact that, with an increase in the range, I is regulated, in the BunoJVi there are no helical grooves with a constant pitch that coincides with one of the steps of the helical groove of the rod . 2.Дроссель по п. 1, отличаю- щ и и с   тем, что щток подпружинен, и усилие пружины направлено по напрйвленню движени  среды.2. The choke according to claim 1, which differs from the fact that the brush is spring-loaded, and the spring force is directed along the direction of movement of the medium. . i /. i / шш/ Фиг, 2shsh / fig, 2
