  • Coupling structure for vacuum exhaust device and vacuum exhaust system
    Patent number: 9273568
    Abstract: Provided is a coupling structure for vacuum exhaust devices each including a pump chamber and a casing that demarcates the pump chamber. The coupling structure includes a first end surface formed on a first side of the casing, and a second end surface formed on the second side of the casing, the second side being the opposite side of the first side. The casing of a first vacuum exhaust device and the casing of a second vacuum exhaust device among a plurality of vacuum exhaust devices are arranged to be directly superposed on each other such that the first end surface provided to the first vacuum exhaust device and the second end surface provided to the second vacuum exhaust device come into contact with each other. By fastening the first end surface and the second end surface, the first vacuum exhaust device and the second vacuum exhaust device are connected to each other such that gas can flow between the casing of the first vacuum exhaust device and the casing of the second vacuum exhaust device.
