Abstract

Изобретение м.б. использовано а клапанах дл  гидравлических систем упргплени  потоками жидкости. Цель изобретени  - повышение герметичности клапана во врем  закрыти  при любом направлении подачи рабочей среди , Корпус 1 имеет надклапанную 2 и подклапанную 3 полости, запорный элемент 4 с полым штоком 5. Подпружиненна  втулка 8 расположена в осевой расточке 9 седла 6. Наружна  стенка расточки 9 и контактирующа  с корпусом 1 часть штока 5 выполнены податливыми в радиальном направлении. 4 ил.Invention m. used in valves for hydraulic systems by fluid flow control. The purpose of the invention is to improve the tightness of the valve during closing in any direction of supply of the working medium. Body 1 has an over-valve 2 and sub-valve 3 cavities, a locking element 4 with a hollow rod 5. A spring-loaded sleeve 8 is located in the axial bore 9 of the saddle 6. The outer wall of the bore 9 and The body in contact with part 1 of the stem 5 is made compliant in the radial direction. 4 il.
