PURPOSE:To make connection with a compressor performable in an easy manner as well as to secure such a vacuum generator as capable of making its structure compact in size, by housing an air control valve and a nozzle accelerating the air controlled at this air control valve, inside a valve body. CONSTITUTION:A through hole 2 is installed inside a valve body 1. A nozzle 11, a valve 5 and a setting member 12 each is inserted into this through hole 2 in order and clamped tight. The valve 5 is coupled with an operating lever 8 so as to make it operatable from the outside of the valve body 1. And, a diffuser 13 is connected to the downstream side of the nozzle 11. Then, compressed air is fed out of a compressor, and spouted out of the nozzle 11. With this spouting, a negative pressure passage 4a is made so as to be turned to negative pressure. |
