2. Description of the Related Art Conventionally, research has been carried out on a fixed-quantity take-out valve, and in particular, various specific researches have been carried out on a fixed-quantity injection valve in an aerosol injection valve. Therefore, regarding the structure of these fixed quantity injection valves, the structure of the valve chamber of the injection valve is made into a fixed quantity chamber, and the space part of the fixed quantity chamber is first added from the inlet of the fixed quantity chamber to the space part of the fixed quantity chamber. The pressurized fluid is allowed to flow in, then the inflow valve is closed, and the pressurized fluid is once stored in the metering chamber by the volume of the space portion of the metering chamber, and the capacity is accommodated. When the valve stem is fully lowered, the metering chamber and the through hole of the valve stem can be communicated with each other.
The pressurized fluid in the metering chamber can be metered from the injection port of the valve stem through the through hole of the valve stem. However, the inflow valves of all of these constant quantity injection valves, that is, the positions where the lower gaskets are arranged are arranged inside the valve housing. A valve or lower gasket must also be provided. Therefore, it is troublesome.
