Design of Hydraulic and Pneumatic Systems
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurised according to the resistance present. A hydraulic system uses an incompressible liquid as its fluid, rather than a compressible gas. The popularity of hydraulic machinery is due to the very large amount of power that can be transferred through small tubes and flexible hoses, and the high power density and wide array of actuators that can make use of this power, and the huge multiplication of forces that can be achieved by applying pressures over relatively large areas.

Hydraulics and Pneumatics By Andrew Parr — Nearly all industrial processes require objects to be moved, manipulated or subjected to some sort of force. This is frequently accomplished by means of electrical equipment such as motors or solenoids , or via devices driven by air pneumatics or liquids hydraulics. This book has been written by a process control engineer as a guide to the operation of hydraulic and pneumatic systems for all engineers and technicians who wish to have an insight into the components and operation of such a system. This second edition has been fully updated to include all recent developments such as the increasing use of proportional valves, and includes an extra expanded section on industrial safety. It will prove indispensable to all those wishing to learn about hydraulics and pneumatics.
