Fluid control valve and system

摘要

Disclosed herein is a fluid control valve comprising a valve seat, and a nozzle proximate the valve seat. The nozzle includes a convergent section and a divergent section formed by a semi-circular profile. Also disclosed herein is a system for controlled feeding of volatile fuel components from a free space of a fuel tank to an engine manifold, the system comprising a storage chamber in fluid communication with the free space of the fuel tank, and a valve in fluid communication between the storage chamber and the engine manifold. The valve includes a valve seat and a nozzle proximate the valve seat. The nozzle includes a convergent section and a divergent section formed by a semi-circular profile.
