EJECTOR, AND HIGH-PRESSURE PASSAGE AND INTAKE HOUSING FOR EJECTOR

An ejector includes a high-pressure passage, a low-pressure passage, and a connection passage. The high-pressure passage includes an upstream end and a downstream end. The upstream end is configured to be connected to a passage through which a high-pressure gas flows. The low-pressure passage is connected to the downstream end of the high-pressure passage. The connection passage is connected to a junction of the high-pressure passage and the low-pressure passage. The high-pressure passage is bent at one or more locations between the upstream end and the downstream end.
