That apparatus also includes a second body having an inlet aperture for second fluid spaced from the first body, an outlet aperture spaced inside the chamber from the aperture for the admixture, and a fluid flow channel decreasing in cross-sectional area from the inlet aperture spaced from the first body to the outlet aperture inside the chamber between opposite ends of the first body. Such first and second bodies jointly comprise a flange structure at the first body and between the inlet and outlet apertures of the second body. An admixture flow channel increases in cross-sectional area away from the aperture at the end of the chamber.Field of SearchCombining of three or more diverse fluidsPlural motivating fluid jets Flow control by varying position of a fluid inlet relative to entrainment chamber With selectively operated flow control means in inlet Flow control means is located in aspirated fluid inlet Single actuator operates flow control means located in both motivating fluid and aspirated fluid inlets With condition responsive valve | |
