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. See similar questions...

The Vortex® Valve is an automatic pressure relief valve that regulates air with changing altitude and temperature, while keeping water out. Storm Case pressure equalization vents (Vortex® valves) are the result of a unique molded housing and a special "Gortex" gas-permeable micro-porous membrane that can repel liquids and micro-particles while allowing gas (air) molecules to pass right through the membrane.

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. See similar questions...

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. See similar questions...

Diet and exercise are key components for ensuring success following Bariatric surgery. Compliance with dietary changed, combined with the right exercise program, will help you lose weight in the post-surgical period, as well as maintain that weight loss over time. These principles, along with many others, are discussed at each Summa Bariatric support group meeting to help keep you on track. See similar questions...

This dual function product contains two valves in one body with a common input and common exhaust. When the toggle is centered in the 2-Way configuration all ports are blocked, in the 3-Way configuration both output ports are open to exhaust. See similar questions...

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. See similar questions...

Laparoscopic gastric bypass results in a shorter hospital stay, less pain, less scarring, and a quicker return to usual activities. Complications such as wound infections and wound hernias are nearly eliminated with the laparoscopic approach. The risk for serious complications (such as leak) is similar with both laparoscopic and open gastric bypass. See similar questions...

During Roux-en-y, the surgeon reduces the size of the stomach to a small pouch, limiting the amount of food the patient can eat and digest. To find out if you are eligible for surgery, see your physician. See similar questions...

The helium release valve works by letting helium out of your watch, and nothing else in. This only comes in handy when you are in a helium-saturated environment such as a dive bell. You can open it on land, but make sure you screw it back down before you submerge it in water. Leaving it open while the watch is under water can let water into the watch. Note: This system is consistant with the Seamaster Professional Chronograph - Chronometer as well... See similar questions...

The pressure relief valve is a spring-supported valve that opens when the limit pressure is reached, thereby discharging excess air via the bypass. The pressure relief valve protects the side channel blower from overload. See similar questions...

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 See similar questions...

A standard technology engine brake consists of a solenoid valve, control valve, and master and slave pistons. These components are assembled into a housing as shown below. When the brake is activated, the solenoid allows oil to pass to the control valve. The control valve moves up and the check ball in the control valve is unseated, allowing oil to fill the master/slave piston circuit. See similar questions...

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.
