It increases the power when a hill is reached (to maintain the same speed within reason, set by the available power available from the engine) and decreases the power when descending. By keeping the engine at the same number of revolutions per minute, and the gearbox in the same gear, this will act as a form of cruise control.

The CAV injector pump used on the Land Rover 2.25L diesel is a governing pump, as well as being a maximum RPM limiter.

Correct. At least this was the case for the 1961 2a I owned, and for the 1981 S3 I owned (pretty certain, but I hardly drove it - engine had been dusted). It is possible some had a different model pump, but I doubt it.

Remember, the 2.25L diesel can be likened to a fast revving tractor engine. The injector pump worked on the governor principle, while modern diesel car injector pumps try to work like an accelerator.
