Claims

[Scope of utility model registration request]

When you pull the trigger that is pivoted on the spray gun body,
In a spray gun in which a needle valve opens against the elastic force of a valve spring to open a fluid jet hole,
An air cylinder having an air supply path connected to the spray gun body and an on-off valve for opening and closing the air supply path are provided, and the on-off valve is configured to open the on-off valve according to the action of the trigger in a pulling direction. A spray gun characterized in that a valve opening lever is provided, and an interlocking lever is provided between the piston and the needle valve to open the needle valve in conjunction with the forward movement of the piston as air is supplied to the air cylinder.
