Hydrostatic transmissions and drive components

Hydrostatics encompasses all technologies based on the equi-partitioning properties of pressure in a liquid at rest.

Among these technologies, hydrostatic transmissions are used where power transmission is of prime importance.

As we shall see later, these transmissions are diversifying in terms of functions, components and performance (see the articles on Pumps and motors and Hydrostatic transmission circuits in this treatise).

There are also hydraulic controls and servo-controls. These are extensively described and analyzed in the Hydraulic Controls and Servo Systems articles of this treatise. We have therefore decided not to repeat all the elements specific to these technologies, which the reader is advised to consult in addition.
