VE Pumps

The helix-and-port distributor injection pump is always an axial-piston unit. As the design relies on a single high pressure element to serve all of the engine’s cylinders, units can be extremely compact. Helices, ports and collars modulate injected-fuel quantities. The point in the cycle at which fuel is discharged is determined by the hydraulic timing device. Mechanical control modules or an electric actuator mechanism provide flow control. The essential features of this injection-pump design are its maintenance friendliness, low weight and compact dimensions.
