CYLINDER HEAD GASKET WITH ONE-WAY COOLANT FLOW VALVE

A head gasket ( 48 ) which acts, when clamped between a cylinder head ( 28 ) and a block ( 22 ) in a liquid cooled internal combustion engine ( 20 ), to form a seal around the combustion chambers ( 24 ). A coolant flow path ( 32 ) routes through the engine ( 20 ) and its directed, in part, through t...

Beschreibung
Zusammenfassung:	A head gasket ( 48 ) which acts, when clamped between a cylinder head ( 28 ) and a block ( 22 ) in a liquid cooled internal combustion engine ( 20 ), to form a seal around the combustion chambers ( 24 ). A coolant flow path ( 32 ) routes through the engine ( 20 ) and its directed, in part, through the cylinder head ( 28 ) and the block ( 22 ), with a corresponding flow opening ( 54 ) formed in the head gasket ( 48 ) to accommodate flow of liquid coolant in a normal direction. The head gasket ( 48 ) includes a one-way valve ( 58 ) positioned in the flow opening ( 54 ) to allow the flow of coolant in a normal direction but to prevent the flow of liquid coolant through the flow opening ( 54 ) in an abnormal, reverse direction. The one-way valve ( 58 ) includes movable gate ( 66 ) which may be biased against a valve seat ( 64 ) in a normally closed condition. The one-way valve ( 58 ) can be made as a loose piece article of manufacture which is held in flow opening ( 54 ) by self-locking retention clips.
