초록

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.

청구항

1. A poppet valve comprising: a valve pin movable relative to a bore, and having a head with a curved outside shape, with a flow cross-sectional area across said poppet valve being defined between an outer diameter of said curved outside shape, and an inner diameter of said bore; andsaid curved outside shape is a parabolic shape. 2. The poppet valve as set forth in claim 1, wherein a step motor causes said valve pin to be movable relative to said bore. 3. The poppet valve as set forth in claim 1, wherein said parabolic shape is determined based upon a fu...
