チ装置。[Claims for Utility Model Registration] A negative pressure changeover switch device capable of selectively operating a first actuating mechanism and a second actuating mechanism individually and simultaneously operating both by means of negative pressure. A cylinder is provided with a negative pressure side port, an actuation side port, and a third port, and the actuation side port can be selectively communicated with the negative pressure side port and the third port by movement of a piston within the cylinder. The first thing I did was
It has three second and third negative pressure changeover switches, each of the negative pressure side ports of these negative pressure changeover switches is connected to a negative pressure source, and the operating side port of the second negative pressure changeover switch. to the first operating mechanism, and the operating side port of the third negative pressure changeover switch to the second operating mechanism, and the third port of the third negative pressure changeover switch. and connecting the third port of the third negative pressure changeover switch and the operating side port of the second negative pressure changeover switch, and further opening the third port of the second negative pressure changeover switch to the atmosphere. A negative pressure changeover switch device characterized by:
