Description
Изобретение относитс к машиностроительной гидравпике, а именно к гидравлическим устройствам, обеспечивающим перемещение выходного звена машины из одного крайнего положени в другое, и может найти применение в объектах, где требуетс возвратно-поступательное движение рабочего органа.The invention relates to engineering hydraulic, in particular, to hydraulic devices that move the output link of the machine from one extreme position to the other, and can be used in facilities that require reciprocating movement of the tool.
Известен реверсивный пневмогидропривод , содержащий цилиндр с реверсивным исполнительным органом и рабочими полост ми, соединенными с напорной и сливной гидролини ми через распределитель , управл емый зоготникомпилотом с управл ющими полост ми lj.A reversible pneumohydraulic actuator is known, which comprises a cylinder with a reversible actuator and working cavities connected to a pressure and drain hydraulic lines through a distributor controlled by a pilot pilot with control cavities lj.
Недостатком известного гидропривода вл етс низкл надежность, обусловленна сложностью системы реверсировани , большим числом агрегатов управлени .A disadvantage of the known hydraulic drive is low reliability, due to the complexity of the reversing system, a large number of control units.
Цель изобретени - повышение надежности привода.The purpose of the invention is to increase the reliability of the drive.
Поставленна цель достигаетс теп, что цилиндр снабжен двум торцовыми клапанами, имеющими подпружиненные толкатели, поочередно взаимодействующие с исполнительным органом, и погости , соединенные с управл ющими полост ми золотника-пилота, примем последние подсоединены посредством дроссе;1ей к напорной гидролинии.The goal is reached to ensure that the cylinder is equipped with two end valves that have spring-loaded pushers that alternately interact with the actuator and are connected to the control spool pilot-pilot, which are connected by means of a dross;
На фиг. 1 представлена схема пневмогидропривода; на фиг. 2 - то «е, другой вариант.FIG. 1 shows a diagram of the pneumo-hydraulic actuator; in fig. 2 - then “e, another option.
