ABSTRACT:
An active reed valve for a fluid passage comprising a sealing means sealingly fixed to the passage walls, and a primary petal seat having a primary seat port and a downstream primary seat end. A flexible primary petal is sealingly attached to the primary petal seat in a cantilevered manner. The primary petal seat and a primary baffle are sealingly attached to the sealing means. The primary baffle is spaced apart from the primary petal seat so that fluid can flow between the primary baffle and petal seat. A positioning means enables the primary baffle to sealingly engage the primary seat wherein fluid flow between the primary baffle and petal seat is directed by the primary baffle toward the primary seat port. Fluid flow through the primary seat port is allowed by the primary petal flexing away from the primary petal seat and fluid back-flow is obstructed by seating of the primary petal on the primary petal seat. The positioning means further enables adjustable separation between the downstream primary baffle end and downstream primary seat end.
