め、近年の廃棄処理事情に則した、分別処理を必要とし
ない廃棄を行えるものである。As described above, the liquid jet pump according to the present invention has an upper ring 24 extending from a lower ring 22 fitted in the lower part of a cylinder via a spring portion 23 which is provided so as to be able to expand and contract upward. Resin spring 25 and a plurality of elastic rods 26 in the circumferential direction protruding downward from the lower end of the lower ring 22 and integrally projecting therefrom, and press-contacting the valve seat 13 at the lower end of the cylinder to form a suction valve 27. Since the valve body 28 is provided, the operating part of this type of conventional pump, which is composed of many members such as a ball valve body for a discharge valve, a coil spring, an annular piston, an upper stem, a lower stem, and a depressing head, is used. A valve-spring member comprising the above-mentioned resin spring and valve body, and a small number of members such as an annular piston, a stem, and a push-down head, can be formed to simplify the production and to entirely employ synthetic resin. Because it is possible to formed, conforming to the recent disposal circumstances, those capable of performing disposal which does not require fractionation.
