The EVR Valve and Control System of Claim

The EVR valve has shown promise in the treatment of symptomatic paravalvular regurgitation. Its success rate has been high and it has a reduced rate of recurrence compared to the CV system. The safety outcomes at thirty days were similar to those with the CV system, but longer follow-up and multicenter experience are needed to assess the long-term safety of the EVR valve.

Vapor management valve 12

A vapor management valve is a device used in a vapor recovery system. It is a device that captures fuel vapors from a fuel tank and controls their output flow through a controllable valve. These valves are typically operated by an ECU that controls the vehicle’s engine.

Magnetic flux collector ring 62

The magnetic flux collector ring 62 for the evr valve allows a high degree of control accuracy while maintaining a lightweight and compact design. The design also allows for direct sensing of the valve position.

Annular-shaped lower segment 66

The annular-shaped lower segment 66 of an EVR valve is a valve member that moves from an open position to a closed position depending on the force induced by pressure. It has multiple annular surfaces and multiple armatures. During the closing or opening process, the armature 88 moves closer to the field sensor 184, creating a magnetic flux field around the sensor.

Control system of claim 21

The control system of claim 21 of an evR valve comprises an input processor block 70 and a valve override logic block 82. The input processor block 70 includes a control state logic block 80 that receives a user override value from block 82. The control state logic block 80 also includes an enable input (EN) and an override input (OVR). The zero hold status input is connected to a zero position hold logic block 96.

Calibration procedure

The EGR valve can be calibrated with a simple procedure. Typically, the calibration process is performed by running the engine 11 for a certain period of time. The threshold for this period may be set to 10 rpm or any other value selected.

Symptoms of a faulty evr valve

A faulty EGR valve can make your vehicle run rough and produce an unpleasant odor. The valve controls the amount of fuel and air mixed inside the combustion chamber. When it malfunctions, too much exhaust gas can enter the engine, causing higher emissions. The exhaust gas contains harmful NOx, which is responsible for the odor and health hazards associated with exhaust fumes. A damaged valve also causes the engine to burn fuel more thoroughly, resulting in the release of hydrocarbons and other toxins.
