OK, seems like there are several types of governor technology available...

- hydraulic speed droop type governor is designed for use on small diesel, gas, or gasoline engines where isochronous control is not required. The design of the speed droop governor is such that the governor operates at a slower speed as engine load increases. It is through this characteristic that stability of the system is achieved and division of load between paralleled units is made possible.

- Pressure Compensated governor is a speed-droop or isochronous governor for controlling the speed of small diesel, gas, and gasoline engines, or small steam or industrial gas turbines. The governor is used to control engines or turbines driving alternators, dc generators, pumps, or compressors.

- dial and lever governors feature lever or dial speed adjustment, a spring-driven, oil-damped ballhead which filters frequency torsional vibrations, an optional speed adjusting motor, electric, oil, water, or pneumatic shutdown, optional droop, and have a wide speed range available.

- Pressure compensated, isochronous control type governor widely used for controlling speed for all types of diesel or gas engines and steam turbines, driving pumps and compressors.

- EGB Governor/Actuator is used with analog or digital electronic controls that provide a proportional 20-160 mA signal to control dual fuel, diesel, and gasoline engines, and gas and steam turbines driving electrical or mechanical loads. During normal operation, the electronic control and actuator section of the EGB regulates fuel to the prime mover. Upon loss of electronic control signal, the standard EGB is adjusted to cause prime mover shutdown. An electronic, pneumatic, or manual starting device is then used to allow prime mover starting and operation under ballhead control. The ballhead section also regulates fuel if the control fails in such a manner as to call for maximum fuel. The EGB governor/ actuator can also be factory set to give maximum fuel (reverse action) on electronic control signal loss. The self-contained hydraulic oil supply makes the governor easy to maintain in almost any installation environment.
