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.
Claims17
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;
- a tapered portion interposed between the stem and the dome, the tapered portion including a seat configured such that the seat seals against an opening in the first longitudinal end of the hollow cylindrical body
- a spring located in the interior of the hollow cylindrical body and interposed between the plunger and an interior edge of the hollow cylindrical body;
- a screw inserted through the second longitudinal end and coupled with the stem of the plunger;
- and
- a plurality of triads coupled with the screw and in contact with an interior wall of the hollow cylindrical body such that the screw may travel linearly through the interior of the hollow cylindrical body.
A method performed by a check valve system comprising:
- coupling a check valve to an oil filter adapter, the 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;
- a tapered portion interposed between the stem and the dome, the tapered portion including a seat configured such that the seat seals against an opening in the first longitudinal end of the hollow cylindrical body;
- a spring located in the interior of the hollow cylindrical body and interposed between the plunger and an interior edge of the hollow cylindrical body;
- a screw inserted through the second longitudinal end and coupled with the stem of the plunger;
- and
- a plurality of triads coupled with the screw and in contact with an interior wall of the hollow cylindrical body such that the screw may travel linearly through the interior of the hollow cylindrical body.
A system comprising:
- 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;
- a tapered portion interposed between the stem and the dome, the tapered portion including a seat configured such that the seat seals to seal against an opening in the first longitudinal end of the hollow cylindrical body;
- a spring located in the interior of the hollow cylindrical body and interposed between the plunger and an interior edge of the hollow cylindrical body;
- a screw inserted through the second longitudinal end and coupled with the stem of the plunger;
