ル用定量弁。[Scope of Claim for Utility Model Registration] (1) A metering chamber for the aerosol contents is connected to the housing fixed to the aerosol container via a gasket via a communication path, and a pressurized spring is inserted into the metering chamber to separate the housing from the housing. A piston biased in the opposite direction is inserted so as to be able to slide in the axial direction, and a communication port communicating with the inside of the aerosol container is opened on the wall surface of the metering chamber in the direction in which the piston is pressed, and the metering chamber is connected to the metering chamber via the outlet path. A stem is slidably inserted into the housing and is in constant communication with the inside of the housing and is biased outwardly by a spring, and an ejection passage that communicates between the inside of the housing and the outside of the aerosol container is separately formed in the stem. This ejection passage is sealed with a gasket when the stem is not pressed, and an inlet is provided in the housing, and when the stem is pressed, communication with the communication passage is closed by the stem, and when the stem is not pressed, communication is closed between the inlet and the communication passage. 1. A metering valve for aerosol, characterized in that the metering chamber is formed to communicate with the inside of the aerosol container via a passage. (2) The aerosol metering valve according to claim 1, wherein the piston is made of a hard material that does not deform due to gas pressurization pressure. (3) The piston has a skirt part made of a soft material that comes into contact with the inner surface of the metering chamber, and deforms inward when pressure filling the aerosol container with propellant. The metering valve for aerosol according to claim 1, characterized in that it forms a passage. (4) The piston has an abutment rod that protrudes outward from the opening edge of the skirt section, and when it is filled with propellant, it abuts against the abutment wall, and the propellant is released between the abutment wall and the opening edge. 4. The aerosol metering valve according to claim 3, wherein the aerosol metering valve has a filling interval of . (5) The aerosol metering valve according to claim 1, wherein the outlet path is formed in the stem to communicate the inside of the housing and the metering chamber via the communication path. (6) The outlet path is formed through the outer peripheral wall of the housing from the metering chamber to the inside of the housing.
2. The metering valve for aerosol according to claim 1, wherein the inside of the housing and the metering chamber communicate with each other without a communication path.
