Rotary-type pump:
- It is a type of fuel injection pump and is also known as a distributor pump system.
- Rotary pumps operate via the rotation of gears, screws, or other mechanisms to create suction and discharge.
- They generate a consistent flow, independent of the outlet pressure, and are capable of handling high-pressure conditions.
- This makes them suitable for applications such as hydraulic fluid power, oil or fuel distribution, and high pressure lubrication systems.
- All the cylinders are fuelled by a single pumping component.
- A rotor with a single inlet and delivery equal to the number of cylinders distributes the fuel to each injector.
- This helps in an even and consistent supply of fuel to all injectors.
- Two plain, diametrically opposed cylindrical plungers form the pumping element, and an extension of these plungers serves as the distributor.
- This addition has an axial hole that connects the pumping chamber to a racked hole, which registers with racked delivery ports required for each engine cylinder.
