PURPOSE: A vacuum generator is provided to increase vacuum destruction speed and to transport a processed product by accurate operation, by constituting a compressed air injection route for vacuum and a separate destruction route for vacuum destruction. CONSTITUTION: A vacuum generator comprises a supply block (200), a pair of solenoid valves (300), a pipe block and an ejector. The supply block comprises an inlet port where the compressed air is injected, and a destruction hole where the compressed air is injected for vacuum destruction. The solenoid valve controls the flow of air. The pipe block is assembled by facing with an opposite side of the solenoid valve to which the supply block is connected. A vacuum generation valve and a destruction perforation vacuum destruction valve are connected through an inlet hole. The pipe block comprises an air-outlet ejecting the compressed air orthogonally to the inlet hole and a vacuum absorbing port where low vapor pressure is developed. The destruction hole is connected to the vacuum absorbing port. The ejector is assembled on the bottom of the pipe block. |
