Abstract: A flow regulating device in a fluid system according to one embodiment may include a housing defining a cavity receiving an orifice body. The orifice body defines a bore extending axially therethrough and includes a flexible end section, with axial slits in one example, to allow the end section to be radially compressed to change a cross-section of a flow passageway when the bore of the orifice body is included in the flow passageway.
