Abstract
Methods and systems are provided for a multi-layered steel gasket for an internal combustion engine. In one example, a system may include a pressure relief device arranged in the multi-layered steel gasket for releasing pressure from one or more fluids flowing through passages of the internal combustion engine.
Claims14
A system comprising:
- an engine comprising a cylinder head and a cylinder block with a multi-layer gasket arranged between the cylinder head and the cylinder block, the multi-layer gasket comprising an interstitial space between layers shaped to flow fluids toward a pressure relief device integrally formed within the multi-layer gasket, wherein the pressure relief device comprises a ball and a spring, and where the ball is pressed against interior surfaces of the multi-layer gasket when in a closed position, and where the ball is spaced away from interior surfaces of the multi-layer gasket when in an open position.
A gasket comprising:
- a first side facing a cylinder head and a second side facing a cylinder block, where the first side and the second side are separated by a space;
- and
- a pressure relief device comprising a moveable portion shaped to fluidly couple the space to a component arranged outside of an engine, wherein the moveable portion is a metal sheet, and wherein the metal sheet comprises a fixed end physically coupled to the first side, and where a free end is in face-sharing contact with the second side in response to a pressure of a fluid being less than a predetermined pressure.
An engine comprising:
- a multi-layer gasket arranged between a cylinder head and a cylinder block, the multi-layer gasket comprising a plurality of apertures for flowing a fluid from the cylinder block to the cylinder head, and where the multi-layer gasket comprises at least one passage arranged in a space between a first layer and a second layer, and where the at least one passage is shaped to receive the fluid from an aperture of the plurality of apertures in a direction perpendicular to an original direction of fluid flow, and where the at least one passage comprises a pressure relief device, wherein the pressure relief device is a spring valve or a flexible sheet, and wherein one or more of the spring valve and the flexible sheet are arranged in the multi-layer gasket.
