Poppet valve with linear area gain

摘要

A poppet valve has a valve pin movable relative to a bore, and with a curved outside shape. A flow cross-sectional area across the poppet valve is defined between an outer diameter of the curved outside shape, and an inner diameter of the bore. Further, a vapor cycle incorporating such a poppet valve is also described.
