Claims

[Scope of utility model registration request]

a pneumatic injection nozzle that injects air pressure-fed from an air source provided outside the vessel; an exhaust passage that exhausts the air injected from the air injection nozzle; and first and second air passages that communicate with the exhaust passage. An intake passage is provided in the body, and a stop valve that is turned on and off in synchronization with the on/off of an air supply control valve provided between the body and an external air source is provided between the exhaust passage and the intake passage. In a vacuum generator with a rapid vacuum release function installed in the flow path downstream from the communication point,
a filter storage chamber in which a filter is inserted into a hollow space extending parallel to the flow path with the longitudinal direction oriented in a direction along the flow path formed between the exhaust passage and the pneumatic injection nozzle; has an air inlet at one end of which is communicated with the end of the filter storage chamber and whose other end is open to the outside, and has a plug for closing the filter storage chamber at the other end of the filter storage chamber; a filter member having a first communication passage capable of communicating with the second intake passage of the vessel body between the filter storage chambers, and further having a second communication passage at an end of the filter storage chamber on the air inlet side; The cylinder chamber has a cylinder chamber extending along the filter member, one end of which is formed so as to be able to communicate with the second communication passage of the filter storage chamber, and the other end of which is provided with a communication hole that communicates with one end of the cylinder chamber. A piston, which is slidably provided at the other end of the chamber and is biased toward the other end of the cylinder chamber by an elastic member, moves to a predetermined position against the biasing force of the elastic member. a detection member having a sensor for detecting that the
A sealing material can be interposed between the communication passages and between the second communication passage of the filter member and the conduction hole of the detection member, and a sealing material can be provided between the four corners of the vessel body perpendicular to the flow path of the vessel body and the filter storage. Connecting screw holes are screwed into the four corners of the filter member perpendicular to the chamber and the four corners of the detecting member perpendicular to the cylinder chamber, and either one of the filter member and the detecting member is connected or 1. A vacuum generator assembly with a rapid vacuum release function, characterized in that both are selectively screwed and fixed to the container body via a connecting screw.
