ABSTRACT:
A reed valve is disclosed for use with a pump having a casing. A check valve unit is provided within the casing for preventing counterflow of fluids to be carried. A suction port communicates with a suction line into which the fluids to be carried flow, and a discharge port communicates with discharge line from which the fluids to be carried out are discharged. Reed valves are mounted on the suction port and on the discharge port of the check valve, respectively, in such a manner that the reed valves cover the suction port and the discharge port so as to be able to open and close. Each reed valve includes a first reed valve and second reed valve. The first reed valve is made of pliable material, and is formed to have a size capable of covering the entire respective suction port and discharge port. The second reed valve is smaller than first reed valve and is superposed on the first reed valve to engage the first reed valve such that the first reed valve can open and close, while enhancing sealability thereof.
