けで、吸気通路２からの空気は供給されない。(B) Prior Art In a conventional pump air replenishment device, as shown in FIG. Connect the check valve 6, and then connect the check valve 6
is communicated with the pressure tank via the conduit 7, and when the pump is operated, the pressure in the negative pressure chamber 9, which communicates with the suction side of the pump through the communication port 8, decreases.
As a result, the diaphragm 10 compresses the spring 11 and reverses toward the negative pressure chamber 9, and at this time, the diaphragm 10
When the water level in the pressure tank 12 is higher than a predetermined level (the level at the lower end of the conduit), the water in the pressure tank 12 is sucked up, and this water flow causes the ball 13 of the check valve 6 to
is pushed up and closes the exhaust passage 3, and at the same time, the check valve 5 of the intake passage 2 opens due to the inflow pressure of the atmosphere and sucks air into the air supply chamber 14. If the water level in the tank 12 is lower than a predetermined level (the level of the lower end of the conduit) when the diaphragm 10 is reversed, air will be sucked up from the pressure tank 12, but the air flow has little upward resistance and will not push the ball 13 upward. Therefore, the air in the pressure tank 12 simply returns to the air supply chamber 14, and no air is supplied from the intake passage 2.

The air supply chamber 14 and the negative pressure chamber 9 have the same pressure, and the reaction force of the compressed spring 11 causes the diaphragm 1 to
0 is shifted to the air supply chamber 14 side, and air is supplied into the pressure tank 12 through the discharge passage 3.

衝突してガーガーと云う異音を発生する欠点があ
つた。 As described above, in the conventional device, the inner diameter of the check valve case 15 is set larger than the outer diameter of the ball 13 in order to prevent the ball 13 from being pushed up by the air flow. Therefore, in the conventional device, when the air in the pressure tank 12 decreases due to various reasons and the pump starts and stops frequently, the ball 13 swings violently within the case 15 due to the water flow and collides with the case wall. It had the drawback of producing a strange noise.

で突出している。(E) Embodiment An embodiment of this invention will be described only with respect to its essential parts, omitting the parts that are configured similarly to the conventional example described above. In FIGS. 2a and 2b, 6' is a check valve connected to the discharge passage 3, and houses a ball 13' as an on-off valve. Like the ball 13 of the conventional example, the ball 13' is configured so that it is pushed up by the pressure of the rising water flow, but not pushed up by the pressure of the air flow. Reference numeral 16 denotes a support member on which the ball 13' is placed, and the check valve case 1 is formed to be approximately twice the outer diameter of the ball 13'.
5' is mounted horizontally on the inner diameter part 15a'. The support member 16 is provided with notches 16b and 16b for dispersing rising airflow at the periphery in addition to a ball support through hole 16a in the center. 17a, 17b,
Reference numeral 17c denotes a plurality of ribs formed protruding from the inner diameter portion 15a', extending in the vertical direction, and preventing undesired swinging of the ball 13' in the horizontal direction. The inner diameter of the support formed by the plurality of ribs 17a, 17b, and 17c is set to be larger than the outer diameter of the ball 13' by some margin, in consideration of the possibility that the ball 13' may become stuck due to water stains, etc. It has been formed. Further, the support portions 17as, 17bs, and 17cs of the plurality of ribs 17a, 17b, and 17c are the dispersion notches 16.
b, 16b protrudes to a position near the inner ends 16bi, 16bi.

る。(f) Effects of the device Since this device is configured as described above, even if the ball is made light to increase the responsiveness of pushing up by the water flow, this lightweight ball will not be affected by the rising air flow. By dispersing the pushing up force into the gap between the check valve case and the check valve case, pushing up can be prevented. Furthermore, since the plurality of ball guide ribs protrudes to a position close to the inner end of the notch for distributing the ascending airflow, even when the ball is seated on the support member, there is no gap between the ball and the check valve case. A gap for distributing the pushing force is maintained by the plurality of ribs, and therefore, it is possible to reliably prevent the lightweight ball from jumping up and closing the discharge passage due to the rising airflow ejected when the pump is started. At the same time, noise caused by the swinging of the ball can be prevented.
