Multi-functional assembly

A unitary structure combining the functions of valve cover, fuel vapor storage container and air admission housing for a vehicle engine of the type including a cylinder head and valve components supported thereon, comprising;

• thin-walled enclosure means having a first open end adapted to receive the valve components and having peripheral edge means thereabout adapted to seal against the cylinder head to prevent the escape of lubricating oil therebetween;
• the enclosure means having first and second interior walls progressively spaced outward from the peripheral edge means thus forming a space therebetween which is substantially filled with a fuel vapor storing material such as charcoal;
• a removable cover member engaging an opposite second end of the enclosure means to form an air flow plenum for the engine defined between the cover member and the second interior wall;
• means for admitting air to the plenum and for directing air therefrom.

A unitary and multifunctional structure for a vehicle engine including a cylinder head with valve components thereon comprising:

• a generally hollow and multi-compartmentalized housing formed of light weight but strong material;
• an open-sided valve cover portion of the unitary structure having a peripheral edge portion about the one side for engagement with the engine cylinder head, thereby enclosing the valve components and preventing leakage of lubricating oil therefrom;
• an elongated hollow air directing portion of the unitary structure for receiving engine air through an inlet at one place for discharging air through an outlet at an opposite place and for filtering air therebetween;
• a vapor storage portion of the unitary structure thus defining an enclosure which holds a vapor storing material;
• the valve cover, air directing and vapor storage portions being defined by a common unitary and thin walled housing structure and including partition walls extending therebetween to separate pairs of said portions one from another.

• an elongated hollow air directing portion of the unitary structure for receiving engine air through an inlet at one end, for discharging air through an outlet at an opposite end for supporting filter means which cleans the engine air;
• the valve cover portion and air directing portion sharing a common wall with the opposite end portions of the latter directed laterally outward from the elongated extent of the former;
• a vapor storage portion of the unitary structure including a wall extending between wall portions of the valve cover and air directing portions thus defining an enclosed space containing a vapor storing material.
