Interface air filter and assembly
An interface air filter and assembly for use with an internal combustion engine is disclosed. The assembly has a housing having an air intake port and an opening. There is an air filter assembly with an air filter having a closed end and an open end and a reducing coupling. The reducing coupling has a first end with a first engaging member having an external circumference and outer surface, a second end with a second engaging member having an external circumference less than the first engaging member external circumference, and the second engaging member has an inner surface. The first end of the reducing coupling is attached to the open end of the air filter. The air filter assembly is in contact with the housing such that the air filter resides within the housing and the outer surface of the first engaging member engages the housing. The inner surface of the second engaging member is adapted to contact an air intake tube outer surface so that air can pass from the air intake port into the housing then through the air filter and into the air intake tube.
1. An interface air filter and assembly for use with an internal combustion engine comprising:
a non-porous single piece housing having an air intake port and an opening;
an interface air filter comprising;
an air filter having a closed end and an open end;
a reducing coupling having a first end with a first engaging member having an external circumference and outer surface the outer surface having a plurality of circumferential ridges extending outwardly from the outer surface to engage an air intake port of a non-porous housing, a second end with a second engaging member having an external circumference less than the first engaging member external circumference, and the second engaging member having an inner surface to engage an outer surface of an air intake tube and the second end adapted to receive a clamp to secure the second end to the air intake tube; and
the first end of the reducing coupling being fixedly attached to the open end of the air filter such that the first engaging member outer surface extends outwardly from the filter; and
the air filter residing within the non-porous housing, and the first engaging member being disposed within the housing opening and the first engaging member being in contact with the housing in a substantially air tight manner;
wherein the inner surface of the second engaging member is adapted to contact an air intake tube outer surface in a substantially airtight manner so that air can pass from the air intake port into the housing then through the air filter and into the air intake tube.
2. The interface air filter and assembly for use with an internal combustion engine of claim 1 , wherein the single piece non-porous housing is a molded structure.
3. An interface air filter and assembly for use with an internal combustion engine comprising:
