Active reed valve

An active reed valve for a fluid passage defined by passage walls, said reed valve comprising:

• a sealing means sealingly fixed to the passage walls;
• a primary petal seat having a primary seat port, an upstream primary seat end, a downstream primary seat end, an upstream primary seat side, a downstream primary seat side and primary seat side edges, said upstream primary seat end being sealingly attached to said sealing means enabling fluid to flow from said upstream primary seat side to said downstream primary seat side through said primary seat port;
• a flexible primary petal sealingly attached to said downstream primary seat side in a cantiIevered manner adlaoent to saId upstream primary seat end wherein said primary petal overlies said primary seat port, said primary petal being adapted to flex away from said downstream primary seat side to uncover said primary seat port;
• a primary baffle having an upstream primary baffle end, a downstream primary baffle end, an upstream primary baffle side, a downstream primary baffle side, and primary baffle side edges, said upstream primary baffle end being sealingly attached to said sealing means, said upstream primary baffle side facing said upstream primary seat side, said upstream primary baffle end being spaced apart from said upstream primary seat end so that fluid can flow between said upstream primary baffle side and upstream primary seat side, said primary baffle being oriented with respect to the passage walls enabling control of the fluid flow direction with respect to the passage walls;
• and
• a positioning means enabling said downstream primary baffle end to sealingly engage said downstream primary seat end, said positioning means enabling said primary seat side edges and primary baffle side edges to sealingly engage said sealing means wherein fluid flow from said upstream primary seat end to said downstzeam primary seat end between said primary baffle and petal seat is directed by said primary baffle toward said primary seat port, fluid flow through said primary seat port being allowed by said primary petal flexing away from said primary petal seat and fluid back-flow in the reverse direction toward said primary seat port being obstructed by seating of said primary petal on said primary petal seat, said positioning means further enabling adjustable separation between said downstream primary baffle end and downstream primary seat end.
