ABSTRACT:
An improvement is obtained in the valve body construction of a check valve which is insertable into the interior of a flexible hose, which valve body comprises a valve body portion having one of an inlet port and an outlet port, and a valve end piece having the other of the inlet and outlet ports, wherein the valve end piece is formed with annular grooves extending in the circumferential direction thereof along the opposite sides across a joint surface between the valve body portion and the valve end piece. With this advantageous construction, there will be no burrs extending outwardly from the joint surface when assembled by welding the mating members. Also, the improvement is furthered wherein the outer diameter of said valve body portion is made slightly greater than the inner diameter of said hose, said valve end piece being provided with a gradually enlarged diametered portion having a largest outer diameter equal to or slightly greater than the outer diameter of said valve body portion, and also with a shouldered portion behind said largest outer diametered portion.
