摘要:A pump apparatus includes a housing having a bore formed therethrough. Apiston is disposed within the bore for reciprocal movement therein. The piston includes a
piston body, and an inlet flange extending radially outwardly from the piston body. Anouter peripheral surface of the inlet flange and a wall of the bore define a first
passageway. A retaining flange extends radially outwardly from the piston body and havea substantially square transverse section. An outer peripheral surface of the retainingflange and the wall of the bore define a second passageway. An intermediate portion isdisposed between the inlet flange and the retaining flange. An annular seal is disposedaround the intermediate portion of the piston body. The seal slidingly engages the wallof the bore, and the seal and the piston cooperate to form a check valve assembly.
