SWIRL TYPE LP - EGR THROTTLE MECHANISM

摘要

A mechanism may include a housing with an inlet passage and an outlet passage joined to the inlet passage by a valve chamber. The valve chamber may contain a plurality of vanes. The vanes may be arranged to: substantially close flow between the inlet passage and the outlet passage; induce swirl between the inlet passage and the outlet passage in both a first direction and a second direction; and be positioned parallel to flow between the inlet passage and the outlet passage. Closing off flow from the inlet passage may enhance flow from an exhaust gas port to the outlet passage.
