Изобретение относитс к гидравлическим устройствам, например, дл генерировани периодических импульсов в системах регулировани и может найти применение в качестве одного из элементов таких систем, а также как устройство дл их исгиытаний.The invention relates to hydraulic devices, for example, for generating periodic pulses in control systems and can be used as one of the elements of such systems, as well as a device for testing them.

Известны гидравлические устройства, содержащие золотники, на цилиндрическом теле которых выполненьт криволинейные вращакмцие каналы tilИзвестны также гидравлические устройства , содержащие дифференциальные поршни вл ющиес беспружинными сервомоторами, обеспечивающие- посто нство расхода масла в гидравлических импульсных лини х, путем изменени открыти щелей дл слива маела 2.Hydraulic devices are known that contain spools, on a cylindrical body of which curvilinear rotates til channels are made. Hydraulic devices containing differential pistons that are springless servomotors are also known, which ensure the consistency of oil in hydraulic impulse lines by changing openings of the slits for draining 2.

В известных устройствах нельз получить импульсное возвратно-поступательное движение поршн , необходимое в некоторых системах регулировани или дл испытани таких систем, например в электрогидравлических системах.In known devices, it is not possible to obtain the pulsed reciprocating motion of a piston, which is necessary in some control systems or for testing such systems, for example, in electro-hydraulic systems.

Кроме того,известно гидравлическое устройство, содержащее корпус, гидродроссель в сливной гидролинии и дифференциальный поршень с тангенциально расположенными щел ми, штокова полость которого сообщена с напорной гидролинией, а бесштокова - с гидродроссепем 3J.In addition, a hydraulic device is known, comprising a housing, a hydraulic throttle in a drainage line and a differential piston with tangentially located slits, the rod cavity of which is in communication with pressure hydraulic line, and rodless, with a hydrothrottle 3J.

Однако и это устройство не обеспечивает импульсное возвратно-поступательное движение .However, this device does not provide pulsed reciprocating motion.

Целью изобретени вл етс расширение функциональных возможностей устройства, например, дл использовани его в качестве генератора пульсаций.The aim of the invention is to expand the functionality of the device, for example, to use it as a pulsation generator.

Поставленна цель достигаетс тем, что по большему диаметру дифференциального поршн установлена перекрывающа щели втулка, профиль торца которой соответствует требуемому закону пульсаций.The goal is achieved by the fact that, over a larger diameter of the differential piston, a sleeve is installed, covering the slits, the profile of the end face of which corresponds to the required ripple law.

На фиг. 1 изображена схема предлагаемого устройства; на фиг. 2 - разрез А-А фиг. 1.FIG. 1 shows a diagram of the proposed device; in fig. 2 - section A-A of FIG. one.

Claims

The device includes a housing 1 in which a differential piston 2 is located. Between the piston and the housing is placed a sleeve 3 with a profiled edge 4, which partially overlaps the tangential slot 5 of the piston 2. ycTpoficTJSo also contains a hydraulic throttle 6, pressure hydraulic 7, the rod end 8 located under the piston 2, rodless cavity 9, hydroline control in 1O, drain hydroline 11. The device works as follows. The working fluid from the pressure line 7 enters the rod cavity 8. Further, the law through the tangential slots 5 mimp of the profile edge 4 of the sleeve 3, the working fluid enters the rodless cavity 9, then through the throttle 6 to the drain. The piston 2 rotates due to the reactive action of the jet of working fluid, and flow through the slots 5. At a fixed throttle position, the cross section of its drain hole remains standing. By virtue of this, the total open section of the gap 5 should remain constant. Therefore, the vertical movement of the piston 2 at each moment should correspond to the height of the edge profile 4 of the sleeve 3, past which the slots 5 pass as they rotate. At the same time, the piston 2 pulsates, alternately connecting control 10 with a caport or with a drain hydroline. The law of pulsations will correspond to the edge profile 4 of the bushings 3. Invention Hydraulic device comprising a housing, a hydraulic throttle in the drain hydrolines and a differential piston with tangential slots whose rod end is communicated with the pressure hydro line, and without rod - with a hydrothrottle, characterized in that, in order to expand the functionality of the device, for example - use as a generator of pulsations, a bushing overlapping slits is installed over a larger diameter of the differential piston, the profile of the end face of which corresponds to the required law of pulsations.
