ABSTRACT:
A selectably variable flowrate expansion apparatus is disclosed comprising a main body having a flow path, the flow path including an inlet and an outlet for the flow of refrigerant therethrough. The main body has a plug member sealably mounted therewithin, this plug member being selectively rotatable relative to the main body between a plurality of discrete flow positions. The plug body has an outlet manifold chamber in communication with the outlet of the flow path in the main body, the outlet manifold being generally coaxial with the axis of rotation of the plug member. The plug body further has a plurality of orifice bores, each of a different predetermined cross section, extending generally radially outwardly from the manifold chamber, there being one orifice bore for each of the above-mentioned discrete flow positions, such that with the plug body in one of its discrete flow positions, a predetermined flowrate of refrigerant will pass through a selected orifice bore of the plug body.
