What is a rotary pump ? ď ľ
A rotary pump is a spinning rotor that makes a hydraulic connection with the different ports on the distributor head
Components
Fuel inlet with inlet pressure variation and fuel viscosity compensation
Transfer pump with pressure regulator
Four-plunger pumping element with enhanced filling capability
Distributor system with reduced high pressure volume
Internal cam ring with scroll plate filing control
Injection timing control with increased light load advance travel
Cold running advance for operation at low engine coolant temperatures
Zero backlash drive shaft with increased shaft locking torque and improved timing accuracy
Metering valve
Mechanical all-speed governor
Plus and minus torque trimmer with excess fuel provision
Electric shut-off Transient advance control
The benefits
It is smaller so less weight
All the shots are fired at the same time
A rotary pump has one fuel-metering plunger
disadvantages
Mechanical causing wear needing more parts changed or fixed
