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.
