Title:
EJECTOR AND REFRIGERATION SYSTEM
Document Type and Number:
Japanese Patent JP2003254300
Kind Code:
A
Abstract:

To provide an ejector wherein failures in a drive motor and a bearing part are reduced and ejector efficiency is improved by applying forced torque to a rotor with nozzles for generating a spiral forced flow of a primary fluid, and also to provide a refrigeration system that uses the same.

The ejector for drawing and/or boosting a secondary fluid by jetting a primary fluid includes the rotor 5 with the nozzles 12 opposed to an open end of piping 3 for supplying the primary fluid, and the drive motor 10 for rotating the rotor 5 with the nozzles. The drive motor 10 is built in a tail member 9 fixed in a diffuser 7. A high speed rotation of the rotor 5 with the nozzles shortens a spiral pitch of a spiral forced flow of the primary fluid jetted from the nozzles 12 of the rotor 5 with the nozzles.
