Claims

[Scope of utility model registration request]

a liquid storage section, a gas flow path into which the liquid is injected,
The cylinder has a front opening that communicates with a gas flow path and a side opening that communicates with a liquid storage section, and a narrow diameter section that is fitted into the cylinder and forms a cavity between it and the inner wall surface of the cylinder. and a large diameter part behind the narrow diameter part that communicates the side opening with the hollow part when moving backward, and blocks communication between the side opening and the hollow part when moving forward; At the front end of
a piston having a valve body that opens a front opening to communicate the cavity and the gas flow path when moving forward, and closes the front opening when moving backward to cut off communication between the cavity and the gas flow path; 1. A fixed quantity supply device for liquid, comprising a spring that normally biases a piston in a backward direction, and an operating section for operating the piston in a forward direction.
