Abstract
A flow resistance setting nozzle capable of easily setting a target flow rate is provided. A metallic block has a through-bore through which a flow path forming metallic pipe is inserted. A pressing member in the form of a rectangular cross-section bar abuts the pipe at a first abut portion. An anvil having a distal end with an arcuate surface is mounted to the metallic block such that the distal end abuts the pipe at a second abut portion that is opposite to the first abut portion. A coarse adjustment screw presses a center portion of the pressing member against the pipe to squeeze the pipe between the pressing member and the anvil to form an orifice in the pipe. Two fine adjustment screws impart a force to the pressing member to further squeeze the pipe until the target flow rate is set.
