Diaphragm pump and fluid cover

摘要

A diaphragm pump housing (12) is designed for molding out of plastics and utilizes a ribbing design which allows a high degree of strength while using a minimal amount of material and/or material having lesser strength. The rib design has an outer circumferential rib (22) about the periphery of the pump housing and a plurality of radially extending ribs (28) which extend outwardly from the center of the housing to the outer circumferential rib (22). Fastener apertures (30) are used to tie together the parts of the pump and the fastener apertures (30) are located between the radially extending ribs (28) in the outer circumferential rib (22). An intermediate circumferential rib (24) is provided adjacent the outer circumferential rib (22). The height of the ribs increases from the center of the housing outwardly to the outer circumference. The radially extending and the circumferential ribs (28,22,24,26) are the same height at locations where they intersect. This high strength design also allows the use of one piece inlet and outlet manifolds without undue flexing or leakage. <IMAGE>
