Heat shield air filter for vehicles
US 20010049925 A1
In a vehicle, it is known to have an air filter as part of an air intake system in vehicle's engine compartment. The air filter consists of a shape with a front narrow opening and a broader base. In the present invention, a new air filter is designed to provide an increased velocity of air passing through it. This new filter has firstly, a three dimensional conical device at the front opening of the filter, and secondly, a shield made of a low heat conductive material which surrounds the air filter and is mounted on a clamp at the bottom of the air filter.

I claim:
1. A three dimensional conical type device at the front end of an air filter of a vehicle.
2. A heat shield which surrounds the air filter of a vehicle.

    1. Field of the Invention
  • [0002]
    The present invention relates to an air filter for automobiles. The air filter is part of an air intake system, and this system allows the air to flow through into the vehicle's engine compartment.
  • [0003]
    2. Description of the Prior Art
  • [0004]
    It is common in automobiles to use a device known as air filter to let the air flow into the engine compartment. The bottom of the air filter is connected to the carburetor of the automobile by means of a pipe. The air enters this filter through a narrow opening at the top. The standard filter has a wire frame visible on the outside. This device, as it is used in automobiles, however, displays the drawback that there is no mechanism other than the narrow opening at the top to facilitate a faster stream of air to pass through the air filter. Also, the standard device used in the industry displays another drawback that it is susceptible to the transmission of heat from the engine compartment.
  • [0005]
    It is an object of the invention to provide a device at the front opening of an air filter to facilitate a faster stream of air into the filter. The air filter consists of a shape with a front narrow opening, and a broader base which is connected to the carburetor by means of a pipe. This inventive device, with an aerodynamic design, increases the velocity of the air as it passed through the filter.
  • [0006]
    A further object of the invention is to provide a device which surrounds the air filter, to be called a “heat shield,” which reduces the amount of heat transmittal from the engine compartment to the air filter. This innovation enables cooler air to pass through the filter.
  • [0007]
    The object of the two inventions is to allow a faster and cooler stream of air to pass through the air filter thereby giving rise to a new air filter for automobiles.
  • [0008]
    The present innovation will be more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings, and wherein:
  • [0009]
    [0009]FIG. 1 is a side view of the new air filter;
  • [0010]
    [0010]FIG. 2 is a top view of new filter; and
  • [0011]
    [0011]FIG. 3 is a sectional view of a preferred embodiment of a heat-shield and an aerodyamic device of the present inventions.
  • [0012]
    The air filter has a heat shield 1 made of a low heat conducting material such as high impact plastic, and an aerodynamic three dimensional conical shaped looking device 2 which is set at the top of an air filter 4. The heat shield 1 is mounted on a supporting clamp 3 and surrounds the air filter 4. The top of the heat shield 1 is narrower than the bottom which is mounted on 3.
