Abstract

A reed valve assembly includes a retainer, one or more reed cages, and a plurality of reed petals. The retainer includes a flange, first and second openings, and a center retainer separating the first and second openings. The reed cages are configured to be advanced from the bottom of the retainer and partially through the first and second openings of the retainer and have at least two inner openings generally facing each other and at least two outer openings generally facing away from each other. The inner and outer openings are configured to be fluidly coupled to the first and second openings of the retainer. The reed petals are configured to extend over the inner openings and the outer openings. The center retainer and reed cages include one or more reed cage grooves and reed cage flanges configured secure the reed cages to the retainer.
