Embodiment Construction

[0014] see figure 1 , generally shows a gasket assembly 20 for providing a gas and fluid seal between two components. The gasket assembly 20 includes a functional layer 22 including an entire protrusion 24 spaced apart from a first opening 26 such as a combustion chamber opening, and a stopper layer 28 disposed between the first opening 26 and the entire protrusion. Between 24. Each of the stop layer 28 and the functional layer 22 includes a half protrusion 30 , 32 located between the first opening 26 and the entire protrusion 24 , which together are referred to as a half stop 34 . Half-stop 34 is formed in a single process step and limits compression across protrusion 24 when gasket assembly 20 is compressed between the two components. As a result, gasket assembly 20 enables high strength, dynamic embossing technology with a substantially single layer and single process step. exist figure 2 An exemplary cylinder head gasket 36 including the gasket assembly 20 is shown in...

Abstract

A gasket for providing a gas and fluid tight between parts of an internal combustion engine, for example around a combustion chamber opening, is provided, The gasket includes a functional layer with a full embossment spaced from the combustion chamber opening. A stopper layer is attached to the functional layer adjacent the combustion chamber opening. After attaching the stopper layer to the functional layer, half embossments are simultaneously formed in the functional layer and the stopper layer adjacent the combustion chamber opening. The aligned half embossments are together referred to as a half-stop. The half-stop maintains the load on the stopper layer, limits compression on the Ml embossment, and protects the full embossment from combustion gases when the gasket is compressed between two parts of the internal combustion engine.

Description

[0001] This application claims priority to U.S. Provisional Application No. 61 / 928,664, filed January 17, 2014, and U.S. Patent Application No. 14 / 598,547, filed January 16, 2015, the entire contents of which are hereby incorporated by reference This article. field of invention [0002] The present invention generally relates to gaskets for providing sealing between components of internal combustion engines and methods of making the same. Background technique [0003] Gaskets are typically used for gas and fluid sealing between two components that are pressed together, such as the cylinder head and engine block of an internal combustion engine. Such gaskets typically include a raised functional layer, also known as a seal bead, to facilitate a tight seal. The functional layer with protrusions is optionally compressed by one or more other functional layers or spacer layers to achieve an airtight and liquidtight seal. However, when the gasket located between the cylinder hea...
