Claims (1)

Формула изобретенияClaim Обратный клапан с эластичным уплотнительным элементом, закрепленным одним концом на выполненном с проходными отверстиями подводящем патрубке и взаимодействующим с его уплотнительной поверхностью, отличающийся тем, что, с целью повышения надежности и долговечности при сохранении уплотняющих свойств и упрощения сборки, между уплотнительным элементом и подводящим патрубком выполнена кольцевая щель, а проходные отверстия выполнены с увеличивающимися в сторону свободного конца уплотнительного элемента поперечными сечениями.A non-return valve with an elastic sealing element fixed at one end to a supply pipe made with through holes and interacting with its sealing surface, characterized in that, in order to increase reliability and durability while maintaining sealing properties and simplify assembly, between the sealing element and the supply pipe is made an annular gap, and the through holes are made with cross sections increasing towards the free end of the sealing element.
