Abstract
Provided is a vacuum ejector pump that operates through high-speed compressed air. The ejector pump includes an external 'C'-shaped clip for securely fixing a casing assembled to a nozzle body, an internal fastening groove and protrusion to prevent arbitrary rotation of the casing relative to the body, and a guide groove and protrusion to indicate the assembly orientation of the body and the casing. Additionally, a check valve that is organically coupled to the body is further included. Accordingly, when using the vacuum ejector pump, the entire structure may be maintained in a robust and stable manner. As a result, vacuum leakage may be minimized.
