Function:
Flow Control: The primary purpose of a non-return valve is to allow fluid (such as oil or coolant) to flow in one direction while preventing backflow. This is essential for maintaining proper pressure and flow within the system.
Prevention of Contamination: By preventing backflow, the valve helps ensure that contaminants do not re-enter the system from areas where they could accumulate, such as the crankcase.
How It Works:
Mechanism: The non-return valve typically consists of a valve body, a spring, and a movable disc or ball.
Flow Direction: When fluid flows in the designated direction (usually towards the lubrication points), it pushes the disc or ball off its seat, allowing the fluid to pass through.
Backflow Prevention: If the fluid attempts to flow in the opposite direction, the pressure causes the disc or ball to seat back against the valve body, effectively blocking the flow.
Spring Action: The spring assists in closing the valve tightly, ensuring that it remains sealed when there is no forward pressure.
Importance:
Lubrication Efficiency: Ensures that oil remains in the system and does not drain back when the engine is off, which is vital for quick start-ups and effective lubrication.
