〔Example〕

Hereinafter, the process of the present invention will be explained based on FIGS. 1 to 8. 11 and 2, reference numeral 1 is a flow meter not shown in FIG. The cam case 30 and the pump case 40 are fixed.

The rotor case 10 is shown in Figure 3, 〒7t'! J shown in figure b, the loose fitting groove 11a and relief groove 111J are connected to the connecting part 1.
A rotor 12 in which H-shaped blades 11 formed by 1C with lυ intersecting each other is rotatably supported via rotors i'1ll13 integrally formed at both ends of the rotor 12. This blade 11 approaches the clam-shaped inner surface 10a of the rotor case 10 and moves in and out while rotating along the inner surface 10a of the rotor case 10. A worm wheel 22 meshes with an A-m 21 fixed to the shaft 13. This worm wheel 22 is connected to one end of a rotating shaft 23 that stands upright in a horizontal plane that includes the center line of the rotor shaft 13. The other end of this rotary shaft 23 is attached to a cam case 30 fixed to the upper surface of the cover case 20, and the end surface of this rotary shaft 23 is provided with a cam case 30 at a position centered on the center line. A camshaft 23a having a center is integrally formed. A cam roller 31 is rotatably attached to the cam shaft 23a, and one end of a slide ll1Il133 arranged perpendicular to the rotation shaft 23 contacts the cam roller 31. Also, this cam case 30 has a slide IP
A blocking member 32 for adjusting the movement 1FJJ m of H133 toward the cam roller is provided so as to be freely adjustable.

This slide shaft 33 reaches from the cam case 30b) into the pump case 40 fixed to the rotor case 10 (d5).
It is elastically biased by a spring 34 so as to come into contact with 1. A diaphragm 41 constituting a diaphragm pump is provided at the other end of this slide @33, and a pump chamber 42 on which this diaphragm 41 acts has an inlet 43 and an outlet 44 formed in opposing directions. In this population of 43 (J

Next, the operation of this embodiment will be explained. As shown in FIG. 8, the valves ↑4.5 of the first tank 2 and the second tank 3 are opened to supply the first and second liquids. Since the pressure of this first liquid acts on the blades 11, the rotor 12 inside the rotor case 10
starts rotating.

This rotation is transmitted to the worm 21 of the cover case 20 via the rotor fiI113 of the rotor 12. Since this worm 21 is meshed with the worm wheel 22, the rotary shaft 23 rotates, which causes the cam roller 31 to act and the slide shaft 33, whose movement amount has been adjusted in advance by the blocking member 32, to move forward. .

Therefore, when the diaphragm 41 acts on the inside of the pump chamber 42 and the slide lll1l133 is opened by the spring 34, the ball 45a on the inlet 43 side moves away from the through hole 45 and the ball 45a on the outlet 44 side moves away from the hole 45 as shown in FIG. The ball 413a is sucked into the through hole 46, and the second liquid enters the pump chamber 42 from the tube 50a. Next, when the slide shaft 33 is used by the cam roller 31 to move forward, as shown in FIG.
When the ball 45a on the inlet 43 side is pressed against the through hole 45, the ball 46a on the outlet 44 side moves away from the through hole 46, and the second liquid that has entered the pump chamber 42 is transferred to the tube 50b.

A slide shaft 33 that can be reciprocated by the action of the cam member is disposed in the cover case 20, and a diaphragm 41 attached to the tip of the slide shaft 33 is attached to the cover case 20, and the outlet 1b of the flowmeter 1 is A die 17 flam bomb having a tube 50b connected at one end to the tube 50b through which the second liquid passes is fixed.

Therefore, it is possible to inject and mix the second liquid at a flow rate proportional to the flow rate of the first liquid, which was indispensable in the conventional 211! An il pump and one automatic valve are not required, so the number of equipment is reduced, the construction is significantly simplified, and not only can it be provided at low cost, but also requires little installation space. Furthermore, since no automatic valve is used, there is no pulsation or uneven mixing. Moreover, since the different liquids are supplied at a constant ratio according to the rotation of the rotor of the flowmeter, a constant mixing ratio is always quickly maintained even when there is a slight change in the liquid flowing through the flow meter. . Furthermore, since the cam member is a cam roller rotatably attached to the camshaft whose center is spaced apart from the center of the rotational shaft, there is little resistance from the slide shaft, allowing the direflamm pump to operate accurately. The effect of special A1, such as doing, is increased by 10.
