Reference numeral 5 denotes a spring material for urging the trigger 4 and the piston forward.
The rear end is engaged with the upright cylinder 3 base. Further, the piston leg 6 projects forward from the cylinder and its front end is engaged with the rear surface of the trigger 4.

Is formed from a material based on a synthetic resin material without using the metal itself, which is different from the conventional one. That is, the present invention is characterized in that the spherical valve body 10 is formed by kneading a synthetic resin material and an inorganic material.

うにする。合計比重を１よりも大とする理由は次の通り
である。Hereinafter, this point will be described in more detail. A material having a specific gravity of 1 or less is used as a synthetic resin material, and a material having a specific gravity of 1.2 or more is used as an inorganic material.
In addition, the total specific gravity of these is set to be larger than the specific gravity of water 1. The reason why the total specific gravity is larger than 1 is as follows.

いは沈降するにしても沈降速度が緩慢でテーパ状吸込み
弁座９を直ちに閉じることができないからである。That is, after the liquid is ejected, the pressure in the cylinder is reduced by the return operation of the trigger 4, and the negative pressure causes the spherical valve body 10 to be separated from the tapered suction valve seat 9 and the liquid in the container to be sucked. Can be raised. When the negative pressure in the cylinder is eliminated and the liquid is completely sucked up, the spherical valve body 10 must sink down in the liquid and close the tapered suction valve seat 9, but the specific gravity of the spherical valve body 10 becomes 1 If it is less than 1, since the specific gravity of the liquid is also 1 or less, the spherical valve element 10 floats and it is impossible to close the tapered suction valve seat 9, or even if it sinks, the sedimentation speed is slow and the taper is slow. This is because the suction valve seat 9 cannot be closed immediately.

Or a mixture of polypropylene and a ceramic powder as an inorganic material in a proportion of 20 to 50% by weight. The reason why the kneading ratio of alumina and ceramic powder with respect to each polypropylene is 20% by weight or more is to make the total specific gravity 1 or more, and the reason why it is 50% by weight or less is because the moldable limit.

Since the pressure is larger than the lower pressure receiving area of the lower end of the cylindrical piston 31, the stem 30 is lowered, the tapered portion 30 a is separated from the short cylindrical discharge valve seat 33, and the liquid is ejected from the nozzle.
