Abstract
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.
Claims7
An ejector, comprising:
- a high-pressure passage including an upstream end and a downstream end, the upstream end being configured to be connected to a passage through which a high-pressure gas flows;
- a low-pressure passage connected to the downstream end of the high-pressure passage;
- and
- a connection passage connected to a junction of the high-pressure passage and the low-pressure passage,
- wherein the high-pressure passage is bent at one or more locations between the upstream end and the downstream end.
A high-pressure passage for an ejector, comprising:
- an upstream end;
- and
- a downstream end, wherein
- the upstream end is configured to be connected to a passage through which a high-pressure gas flows, and
- the high-pressure passage is bent at one or more locations between the upstream end and the downstream end.
An intake housing that defines a part of an intake passage of an internal combustion engine, the intake housing comprising:
- a main body that defines the intake passage;
- and
- an ejector portion that defines a connection passage through which a fuel vapor flows, wherein
- the ejector portion includes:
- a high-pressure passage including an upstream end and a downstream end, the upstream end being configured to be connected to a passage through which a high-pressure gas flows;
- a low-pressure passage connected to the downstream end of the high-pressure passage;
- and
- the connection passage 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, and
- at least a part of the ejector portion is integrally molded with the main body.
