Abstract

В изобретении предлагается диафрагменный насос, который содержит диафрагму (33), выполненную с возможностью перемещения между первым и вторым положениями вдоль первой оси; нагнетательную камеру (24) на одной стороне диафрагмы, причем нагнетательная камера выполнена с возможностью заполнения нагнетаемым флюидом; передаточную камеру (20) на другой стороне диафрагмы, причем передаточная камера заполнена рабочей жидкостью; первый и второй однопутевые клапаны; резервуар для флюида, имеющий флюидную связь с передаточной камерой через первый и второй клапаны; цилиндрический золотник (42), расположенный в передаточной камере для управления потоком флюида через первый и второй клапаны, причем цилиндрический золотник выполнен с возможностью перемещения вдоль второй оси, которая не совпадает с первой осью, между множеством положений относительно отверстий для первого и второго клапанов.
