Abstract
A check valve may be used to enable desired flow rates of fluid in a particular direction. In some examples, the check valve may have a hollow cylindrical body and a threaded portion on an exterior wall of the hollow cylindrical body such that the check valve may be coupled with an assembly, such as an adapter for a vehicle engine. The check valve may include a plunger having a dome shaped portion (e.g., cone shaped, semi-hemispherical shaped, rounded cone shaped, etc.) that extends out of the hollow cylindrical body into free space when the check valve is in an open position and forms a seal with the hollow cylindrical body when the check valve is in a closed position.

A check valve comprising:
- a hollow cylindrical body having a first longitudinal end and a second longitudinal end;
- and
- a plunger comprising:
- a stem slidably disposed at least partially in an interior of the hollow cylindrical body;
- a dome protruding from the hollow cylindrical body and having a circumference larger than a circumference of the hollow cylindrical body;
- and
- a tapered portion interposed between the stem and the dome, the tapered portion including a seat configured to seal against an opening in the first longitudinal end of the hollow cylindrical body.
