ABSTRACT:
A device in fluid-conducting unit for use in a supply line for carrying fluid with pressure from a source of the fluid to a tool comprises a coupling member having first and second open ends and a fluid passageway extending between the open ends. The fluid passageway has inner walls defining first and second sections with the second section having a larger diameter than the first section. A sloped surface connects the walls of the first section with the walls of the second section and a convergingly-shaped hub body is mounted within the second section for longitudinal movement therein between a first position of the hub body at the second end for providing a large fluid exhaust area and a second position at the first end for providing a reduced exhaust area, the convergingly shaped hub body being provided with a first end adjacent to engage the sloped surface and a plurality of spaced-apart wings projecting from the hub body to the inner walls of the second section, the wings interacting with the sloped surface at their front edges and having a longitudinally extending elongate outer surface for engaging the inner wall of the second section.
