Abstract

A reciprocating cylinder seal assembly having an elastomeric seal with a radially inwardly directed oil seal lip and a radially inwardly directed gas seal lip, wherein both lips are in contact with a reciprocating engine cylinder liner elastomer-to-metal sealing contact. The assembly further has a U-seal holder attached to the elastomeric seal, wherein the U-seal holder is placed in direct intimate contact with the cylindrical motor case. The U-seal retainer and the reciprocating engine case can be separated from and contacted by the main portion of the J-shaped gas shield, which has a hook portion between the oil seal lip and the manifold port, where the J-shaped The hook portion of the gas shield has a metal back ring embedded in it.

Description

technical field [0001] The device relates to a valve sealing assembly of an engine. More specifically, the present apparatus relates to engine cylinder liner seal assemblies for reciprocating cylinder engines. Background technique [0002] For vehicles with reciprocating cylinder engines, the valve seal assembly cooperates with the engine reciprocating engine to provide lubrication while trapping engine gases within the engine intake and exhaust. To accomplish these functions, the valve seal assembly may include an engine elastomer seal with an elastomer-to-metal seal between the engine elastomer seal and the engine reciprocating shaft. An example of such a valve seal assembly is the Dana Corporation AllBond TM assembly where the retainer fits around the valve guide. [0003] Unfortunately, current valve seal assemblies and methods used with existing reciprocating cylinder engines having reciprocating cylinder liners (also known as sleeves) experience significant radial m...
