Abstract
A suction reed valve includes a central ring shaped body having a pair of tabs extending radially outward. One of the pair of tabs is fixed to a valve plate and the other tab is free to move. A necked down region is located between the fixed tab and the central ring shaped body to facilitate the bending/deflection of the suction reed valve.
