CHECK VALVE (TWO-WAY) CONSTRUCTION/OPERATION [L3 R.H.D.]
BUE011642913N02
• Consists of valves and a body.
• Installed on the charcoal canister protector.
• When the charcoal canister discharges evaporative gas, valve A opens, and the gas is released to the atmosphere through port B.
• When the charcoal canister takes in atmospheric air, valve B opens and intake air enters through port C.
• If the check valve is flooded with water, valve A closes due to water pressure to prevent water from entering. The end of the hose connected to port C is located in a high position, and air intake occurs at this heightened position.
