Abstract

A reed valve includes a generally wedge shaped reed cage or block defining a fluid flow passage and having substantially coplanar discharge ports. A reed is mounted at a common hinge end to the reed cage and has a plurality of petals each of which overlies a corresponding one of the ports. The petals have predetermined edge profiles to establish different transverse widths at their hinge axes so that the petals overlying outer low pressure zones in the reed cage lift from their port closing positions at a lower fluid pressure than the petals that overlie higher pressure zones in the reed cage, thereby providing multiple stage lifting and reflex action by the reed petals relative to the reed cage ports.
