The Bypass valve (BPV) performs the same function as the BOV above. The only difference is the air is recirculated back into the intake tract in front of the turbo, not released to the atmosphere. The BPV recirculates excess air when the throttle is closed during shifts or deceleration, creating a muffled "woosh" sound. Source: TurboByGarrett.com - Turbo Tech101

The best kept secret in forced induction is the little known bypass valve. This small valve, when properly installed between the supercharger and the air throttle body, allows the supercharger to become extremely efficient in terms of economy and parasitic power loss. Our M90 supercharger uses less than 1/3 of 1 HP at 60 MPH cruising. The bypass is operated by a vacuum actuator control unit that is normally closed.

A: AEM's patented air bypass valve virtually eliminates the chance of hydro-lock in the unlikely event the filter of your AEM Cold Air induction system becomes submerged in water. The valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in.

The EGR re-routes some of the exhaust gases back into the intake/combustion chamber. This is basically done to reduce emissions. Blocking it off will reduce the temperature of the intake since the gases fed back through the EGR are very hot. Lower intake temperature produces more power, but the amount of gases that are passed through the EGR is VERY minimal and probably won't result in much (if any) performance gain. The drawback is increased emissions.

It is a butterfly valve like the one in the throttle body (see picture). The default is closed. When vacuum is high (idle-cruising) an actuator opens the bypass valve so that intake air bypasses the compressor. When accelerating, vacuum decreases and the bypass valve instantly closes. Intake air now goes through the compressor, building boost. More power means more fuel means larger injectors. However, in order to pass CARB, the base kit had to use the stock injectors.

In the event of the CAI filter being completely submerged in water (eg: deep puddle) this gives the CAI a seperate "bypass" area to draw air into the engine, without taking in water to the engine - resulting in hydrolock (your engine is pooched due to ingesting water). Cheap insurance for CAI.

Mainly construction. The mitsu valve is all plastic, the GFB unit is all metal. The latter is also adjustable.

An anti-reflux valve prevents urine backflow into the tubing, which could lead to urinary tract infection.

The slug valve stops the flow of product when excessive water is collected in the filter/separator sump. It works in conjunction with the float control valve. The slug valve can also be furnished with "rate of flow " control which is used to control flow through the filter/separator and with a check valve feature to prevent back-flow. <TOP>

The Blow-Off valve (BOV) is a pressure relief device on the intake tract to prevent the turbo's compressor from surging from the backed up pressure waves caused by a suddenly closed throttle. BOV's do not control boost levels. The BOV should be installed between the compressor discharge and the throttle body. When the throttle is closed rapidly, the airflow is quickly reduced, causing flow instability and pressure fluctuations.

The mitral valve is one of four valves in the heart. It regulates blood flow from the left atrium into the left ventricle, the heart's main pumping chamber. A normal mitral valve has two flaps, or leaflets. When the heart pumps, blood forces the flaps open, and blood flows from the left atrium (upper chamber) to the left ventricle (lower chamber). Between heartbeats, the leaflets close tightly so that blood does not leak backwards through the valve.

A Blow Off Valve (BOV) is a valve that is mounted on the intake pipe after the turbo but before the throttle body. A BOV's purpose is to prevent compressor surge. When the throttle valve is closed, the vacuum generated in the intake manifold acts on the actuator to open the valve, venting boost pressure in order to keep the compressor out of surge. Bypass valves are also referred to as compressor bypass valves, anti-surge valves, or recirculating valves.

A standard air bypass valve should be used on all supercharged applications where the supercharger is making more than 6 psi. The advantages of using an air bypass valve include eliminating compressor surge (the noise heard during deceleration) for quieter supercharger operation, and reduced heat soak in the discharge tube and the supercharger.

Components and complete kits are available to connect the output from an ABV to throttle bodies. More information is available on a specific instruction sheet .

The beaded part of the MAS adapter needs to be cut off. This removes about a half inch of material from the adapter. If you purchased your bypass valve while ordering the AEM intake from RRE, this has already been done to your MAS adapter (they cut it for you). The adapter itself can cover up to half of the bypass valve without effecting it's function. If more of it is covered up, it is not guaranteed to work when needed.

The purpose of the Global JXDM is to provide a consistent, extensible, maintainable XML schema reference specification for data elements and types that represent the data requirements of the general justice and public safety communities. A secondary goal is to provide a baseline model for the data dictionary that can be represented in advanced technologies independently of XML Schema.

This mailing list provides an English-language forum for discussion of topics related to Hayao Miyazaki, a wonderful storyteller and a director of a number of box-office successes in Japan. This list was created in the United States at Brown University in 1991 to facilitate discussion among fans of Miyazaki's works.

A Bypass System is a connecting duct installed between the supply and return ducts in order to relieve excess static pressure in the ductwork that is caused by the shutting down of all but one or two small capacity zones.

The bleeder valve serves several functions. The core reason is that it allows you to easily adjust the pressure in the system. But it’s important to note that the bleeder valve also allows the pump to circulate a little bit of fresh air through it so any off-gases from adhesives are allowed to escape. The pumps are continuous duty, but they can generate some heat which can cause the off-gases to create a build up of residue.
