Claims

[Scope of Claim for Utility Model Registration] A vacuum pressure control valve comprising a main valve and an electromagnetically driven pilot valve for driving the main valve, the main valve having an output port communicating with a suction pad connected to a vacuum source. a vacuum pressure valve section and a supply valve section, each having a switching position that communicates with a vacuum pressure port that communicates with a vacuum pressure port that communicates with the source, and a switching position that communicates the output port with a supply port that communicates with a pressurized air source, and driving these valve sections to open and close; The pilot valve body is provided with a pilot fluid for opening the vacuum pressure valve part to the main valve drive part when the valve member is in a first switching position by energizing one solenoid. At the same time, the second solenoid of the valve member is energized by the other solenoid.
At the first switching position, a flow path is provided in the drive section of the main valve to supply pilot fluid for closing the vacuum pressure valve section and simultaneously opening the supply valve section, and the valve member is temporarily placed in the first switching position. 1. A vacuum pressure control valve characterized by being provided with a detent mechanism section that holds the vacuum pressure.
