Claims

[Scope of utility model registration request]

A body having a negative pressure signal port, an atmospheric input port, and an atmospheric output port; a diaphragm piston that divides the inside of the body into a negative pressure chamber communicating with the negative pressure signal port and an atmospheric chamber communicating with the atmospheric input port; a valve member that controls opening and closing of communication between the atmospheric chamber and the atmospheric output port by displacement operation of the piston; a first spring disposed in the atmospheric chamber that biases the piston in the opening direction of the valve member;
a second spring disposed in the negative pressure chamber, urging the piston in a direction opposite to the first spring, and having a larger installation load than the first spring; a second spring integrally coupled to the piston; It has a connecting rod that is integrally displaced and operated, and a switch mechanism that controls the electrical passage ON"-0FF by the operation of the connecting rod, and detects the negative pressure supplied to the signal port to connect the valve member and the switch mechanism. A negative pressure control valve device with a switch mechanism, characterized in that it operates simultaneously.
