Abstract
A Vacuum Relief Assembly for I.C. Engine Intakes is disclosed. Also disclosed is a device that permits outside air into the intake tract of an internal combustion engine in the event of an excessively high vacuum condition within the intake tract. Furthermore, the device is constructed from durable materials and resists the excessive temperatures found in the engine compartment of a vehicle. Still further, the device is made from two half-cylindrical sections that mate to one another around the intake tract to form a cylindrical attachment. The method of installation enables the device to be installable onto the intake tract in situ, and without the need to cut out a section of the tract.
Claims14
A vacuum relief assembly, comprising:
- a first sleeve half defining a substantially semicircular shape, further comprising a relief valve means associated therewith;
- a second sleeve half defining a substantially semicircular shape, further comprising a relief valve associated therewith, said first and second sleeve halves cooperating to be attachable to form a substantially circular vacuum relief assembly.
A method for adding a vacuum relief assembly to an intake tube of an internal combustion engine, comprising the steps of:
- creating at least one aperture in a wall of said intake tube;
- placing a first sleeve half defining a substantially semicircular shape, further comprising a relief valve means associated therewith in contact with said wall;
- placing a second sleeve half defining a substantially semicircular shape, further comprising a relief valve means associated therewith, said first and second sleeve halves cooperating to form a ring-shaped device around said tube over said aperture;
- and
- attaching said first sleeve half to said second sleeve half.
A pressure relief valve in combination with an intake tract of an internal combustion engine, said combination comprising:
- an air intake tube having a first end in communication with an external environment and extending to a second end in communication with a throttle body of said internal combustion engine;
- and
- a pressure relief valve assembly connected to said air induction tube disposed between said first and second ends of said air induction tube, wherein when a pressure differential between said external environment and with said air induction tube reaches a predetermined threshold, said pressure relief valve opens establishing a path to said external environment thereby providing a supplemental source of air to said throttle body, said assembly comprising:
- a first sleeve half defining a substantially semicircular shape, further comprising an annular wall having at least one relief valve flap segment formed therein;
- a second sleeve half defining a substantially semicircular shape, further comprising an annular wall having at least one relief valve flap segment formed therein, said first and second sleeve halves cooperating to be attachable to each other to form a substantially circular shape.
