Claims

[Scope of utility model registration request]

A nozzle block 3 having a nozzle hole 3a and an ejector block 2 having an ejector hole 2a corresponding to the nozzle hole 3a are fitted into a hole drilled in the pump body 1, and a gap is formed between the nozzle hole 3a and the ejector hole 2a. An air chamber 4 formed in the main body 1 is connected to a suction lower provided on one side of the main body 1, and a pilot valve 8 for opening and closing the nozzle hole 3a is slidably fitted into the hole of the main body 1 at the tip 8a. The air gap 10 around the tip 8a is connected to a compressed air inlet 9 provided on the outside of the main body, and pressurizing parts 11 and 12 with different pressure receiving surfaces are provided at the front and rear of the pilot valve 8, respectively. The pressurizing part 12 of the small pressure-receiving surface is communicated with the compressed air inlet 9, and the pressurizing part 1-1 of the large pressure-receiving surface is alternately connected to the atmosphere with the compressed air inlet 9 on the outside of the main body 1. Connecting switching valve 1,
4 is provided, and when the switching valve 14 is actuated to communicate the pressurizing part 11 with the large pressure receiving surface to the compressed air inlet 9, the pilot valve 8 changes the pressure of the pressurizing part 11 due to the difference between the pressure receiving surfaces of the two pressurizing parts. The ejector pump is characterized in that when the pilot valve 8 moves in the direction of the pressurizing part 12 and opens and closes the nozzle hole 3a, the pilot valve 8 moves in the direction of the pressurizing part 12 due to the pressure difference between the two pressurizing parts. .
