Abstract
To provide a breathing device for an internal combustion engine, wherein the structure around the check valve is simplified so that the engine as a whole can be manufactured compact, the breathing device includes a check valve (34) for fluid connecting, a crank chamber (27) and a rocker arm chamber (31) in the combustion engine. The check valve (34) is disposed in a head gasket (35) that is interposed between a cylinder block (6) and a cylinder head (7). The check valve (34) is in the form of a reed valve separate from the head gasket (35) and is supported by the head gasket (35) by means of a rivet (36).
Claims18
A breathing device for an internal combustion engine which comprises a check valve for fluid connecting a crank chamber and a rocker arm chamber in the combustion engine, said check valve being disposed in a head gasket that is interposed between a cylinder block and a cylinder head of the engine.
In an internal combustion engine having a crank case connected to an engine block, a cylinder head mounted on the engine block and a rocker cover connected to the cylinder head, the improvement of a head gasket comprising:
- a head gasket unit of a size to seal the engine block to the cylinder head including a valve portion supported by the head gasket unit between the engine block and cylinder head to control fluid flow.
In an internal combustion engine having an engine block and a cylinder head mounted on the engine block with a fluid passageway extending between the engine block and the cylinder head, the improvement of a head gasket comprising:
- a check valve mounted in the head gasket and operatively positioned in the fluid passageway, the check valve including a valve opening in the head gasket and a valve portion extending approximately flush with the head gasket.
