摘要
The mass flow rate of helium from a container is controlled by two disks having highly polished mating surfaces and mounted for rotation relative to one another. Each of the disks has at least one axial through passage, at least one of the disks having a through passage which is eccentric to the axis of rotation of the disk. Use of a plurality of through passages in one of the disks, one or more capillary grooves emanating from one of the through passages in one disk and terminating in the circular path described by the through passage in the other disk for controlling the flow rate is illustrated. For example a step motor in combination with a wobble plate rotates one disk in very exact steps relative to the other.
