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.

Abstract: A single bolting flange arrangement for variable inlet guide vane (VIGV) connection includes a connection arm connected to a stem of the VIGV to rotate the VIGV. The connection arm is driven by a drive pin received in a slot of the connection arm. The connection arm has a bolting flange and the stem of the VIGV is fastened to one side of the single bolting flange by a bolt/nut assembly.
