In a vane pump, should the trailing edge of the vane always face away from the feed notch?

In a vane pump, the orientation of the vanes is critical for optimal performance. The trailing edge of each vane should actually face towards the feed notch rather than away from it. This design ensures that as the rotor turns, the vanes can effectively scoop fluid from the feed notch and push it into the discharge side. This movement creates the necessary suction to draw in fluid and helps maintain continuous flow without cavitation or stalling.

If the trailing edge faced away from the feed notch, it would disrupt the flow of the fluid into the pump, leading to inefficient operation and potentially damaging the pump. Therefore, it is essential that the configuration allows for proper engagement with the fluid being pumped, making it clear that the answer is false.
