Definitions
- This in invention relates to a simple and secure way for mounting a resonator into an air intake system for a vehicle, and in particular to a connection system utilizing a vacuum seal with a vibration isolator
- ETC electronic controls
- the ETC systems are typically mounted into a housing which includes the fluid path, the throttle and an associated control
- the ETC is placed between a supply of air, and the engine
- the air resonator assembly is designed to limit noise traveling from the engine outwardly along the air flow line
- the air resonator is designed to provide a volume to deaden or eliminate noise from the engine
- known air resonator systems have had a female hose which extends over a bore on the throttle body A clamp is then tightened onto the hose, squeezing it onto the body This connection is somewhat time consuming, and not always reliable Hose connections
- a connection between a air supply line component and an air resonator utilizes an internal vacuum seal sealing an interface between the two components
- the air resonator is connected onto a boss on an ETC body
- the vacuum seal is preferably mounted within a groove in an outer periphery of the boss associated with the ETC body
- the vacuum seal preferably has a cylindrical lip extending in a direction away from the resonator and at an angle Moreover, forward of the seal cylindrical lip are a pair of integrally molded bumpers or vibration isolators The vibration isolators deaden any effect of vibration between the two components such that the connection between the two remains strong
- the present invention thus allows the connection of the air resonator directly to the ETC without the requirement of any hose clamps, etc Moreover, the connection is more reliable than the prior art given the friction connection between the two components through the use of the vacuum seal
- Figure 1A shows a schematic view of the inventive system with an air resonator attached
- Figure IB shows the air resonator removed
- Figure 2 is a cross-sectional view of the inventive seal
- An air resonator body 20 is connected to an air cleaner 24 for delivery of clean air to a vehicle engine 28
- the air flows through an air supply line
- An electronic throttle control (ETC) body 30 is mounted between resonator 20 and the engine 28
- a control 32 and an associated throttle valve 34 are positioned within the internal flow line 35 in body 30
- Upstream of the throttle 34 is a connection 36 for communicating the line 35 to the air resonator body 20
- the air resonator body has a path 38 communicating with the passage 36, and communicating with an internal volume in the air resonator body 20, as is known
- the basic structure of the ETC 30 and the air resonator 20 are as known It is the connection between the two which is inventive here
- a boss 40 extends downwardly to define passage 36.
- a groove 42 is formed in the outer periphery of the boss 40.
- a vacuum seal 44 is positioned within the groove 42.
- the vacuum seal is preferably molded out of a suitable rubber or elastomer, in one preferred embodiment was formed of a silicon rubber.
- An integral seal lip 46 extends away from the air resonator at an angle from the remainder of the body of the seal 44.
- Bumpers or vibration isolator 48 are also positioned between the boss 40 and the inner periphery 50 of a neck portion 51 of the resonator body 20.
- the inner diameter 50 of the neck 51 squeezes the seal 40, its seal lip 46, and the vibration isolators 48 away from a free position.
- An interference fit between the seal 44 and the inner periphery 50 is sufficient to retain the air resonator 20 solidly on the boss 40.
- the interference fit between the lip 46 in its free position and the inner periphery 50 is on the order of 5 millimeter.
- the seal 44 is at its free position. As mentioned above, in the free position, the lip 46 extends approximately 5 millimeters radially outwardly from the position shown in Figure 1 A.
- lip 46 extends at an angle A from a rear body 52 of the seal 44.
- An end 54 of the seal lip 46 has an extreme portion which is spaced from a central axis X of the seal 44 by 5 millimeters more than the inner periphery 50 of the air resonator 20.
- the angle A is approximately 45°.
- the vibration isolator 48 is preferably formed of a pair of lips 56 and 58.
- the lip 56 extends slightly radially outwardly more than the lip 58.
- a central valley 60 is positioned between the two.
- the use of the two spaced lips 56 and 58 ensure adequate vibration isolation between the connection and the vacuum seal 54.
- the lip 46 by extending away from the air resonator 20, is pulled further into contact with the inner periphery 50 by a vacuum drawn within the passages 36 and 38. In this way, a more fluid tight seal is ensured. It is desirable to ensure a fluid tight seal, as dirty air which passes seal 44 moves into the passage 45 and potentially to the engine 28, which would be undesirable.
- the present invention discloses a unique connection between an air resonator and an ETC valve or other throttle body.
- the unique connection provides a simplified and more beneficial connection between the two.
