Claims

[Scope of utility model registration request]

a negative pressure on/off valve that outputs negative pressure from a negative pressure introduction pipe from an output negative pressure pipe by energizing a negative pressure coil wound around a negative pressure core via a bobbin to drive a negative pressure plunger; Atmospheric pressure on/off valve that sends atmospheric pressure from the atmospheric introduction pipe to the output negative pressure pipe by energizing the atmospheric pressure coil wound around the atmospheric pressure core via a bobbin to drive the atmospheric pressure plunger. Due to the respective opening and closing operations,
In the composite electromagnetic valve for controlling output negative pressure, the end surfaces of the negative pressure core and the atmospheric pressure core are joined to each other, and atmospheric pressure is sent from the atmosphere introduction pipe to the output negative pressure pipe. An atmospheric passage is formed along the axial direction of each of the atmospheric pressure core and the negative pressure core, and two poles of a connector for energizing the negative pressure coil and a connector for energizing the atmospheric pressure coil are formed. A composite solenoid valve characterized by combining two poles of a connector.
