the high-pressure gas that was in the right capillary tube to escape into the suction tube. The left port in the pilot valve is closed as its needle moves to the right, blocking the left capillary tube. The open port on the pilot valve, due to its size, can reduce pressure faster than gas can bleed through
A capillary tube is a very thin tube made of a rigid material, such as plastic or glass. The tubes are used to collect samples of liquids, which will flow up into the tubes against the effects of gravity in a process called capillary action. They are commonly used in medical and research fields to extract very small samples of liquids to be ...
