Claims

[Scope of utility model registration request]

an outer member that is at least partially tapered and has a hole passing through from one end to the other end; an inner member formed in a tapered shape, the outer member having a fluid inlet communicating with the outer member at one end thereof and a fluid outlet communicating with the other end thereof; A spiral groove, a groove with equal pitch, or a thread is provided in any part of the part, and the contact area between the outer member and the inner member is such that at least a part thereof is in airtight or liquid-tight contact with the outer member and the inner member. A device for adjusting the resistance of a fluid flow path, characterized in that an adjustable gap for a fluid flow path communicating with a fluid inlet and a fluid outlet is formed between the outer member and the inner member by grooves or threads.
