Two-staged compression of a sealing gasket
Abstract
Abstract A SUPPORT AND A PANEL ASSEMBLY INCLUDES AN ELONGATE MEMBER HAVING TWO THICKNESS DIMENSIONS WHICH PROVIDE A THICK LIP AND THIN LIP. THE PANEL ASSEMBLY COMPRISES A PANEL HAVING AN UPPER AND A LOWER SURFACES ON WHICH A RESILIENT CLOSED-CELL SEALING GASKET IS BONDED TO THE PERIMESTER OF ONE OF THE SURFACES WITH THE GASKET ENGAGEABLE WITH THE THICK LIP AND THE THIN LIP OF THE ELONGATED MEMBER. A CLAMPING MEANS FOR BIASING THE PANEL AND THE ELONGATED MEMBER TOGETHER CAUSES A TWO-STAGED COMPRESSION OF THE SEALING GASKET. THUS, A ZONE OF GREATER COMPRESSION OF THE GASKET OCCURS BETWEEN THE THICK LIP AND THE SURFACE OF THE PANEL AND A ZONE OF LESSER COMPRESSION OF THE GASKET OCCURS BETWEEN THE THIN LIP AND THE SURFACE OF THE PANEL. SHOULD PARTICULATE MATTER DIFFUSE THROUGH THE GASKET AT THE ZONE OF GREATER COMPRESSION BECAUSE OF THE DETERIORATION OF THE SEALING INTEGRITY OF THE GASKET, THEN THE PARTICULATE MATTER WILL BE EXCLUDED FROM PASSING THROUGH THE GASKET AT THE ZONE OF LESSER COMPRESSION.
