Abstract
An ejector for use in a refrigeration system has a mixing tube or diffuser which is partitioned into multiple flow passages. Selectively directing a continuously flowing primary high velocity fluid jet stream, which stream entrains a secondary fluid, cyclically into each of the multiple flow passages creates an effective pulsing of the primary high velocity fluid jet stream with respect to each flow passage. Pulsing the primary high velocity fluid jet stream in this manner enhances the mixing and compression of the primary high velocity fluid jet stream and the secondary fluid in the diffuser.
