Hydraulic machinery Wikipedia

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 pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses ...

Basic Principles Of Hydraulics Bright Hub Engineering

Basic Hydraulic Principles. A simple hydraulic system consists of hydraulic fluid, pistons or rams, cylinders, accumulator or oil reservoir, a complete working mechanism, and safety devices. These systems are capable of remotely controlling a wide variety of equipment by transmitting force, carried by the hydraulic fluid, in a confined medium.

INTRODUCTION TO BRAKING SYSTEM Tezpur University

WORKING OF DRUM BRAKES Drum brakes work on the same principle as the disc brakes. Shoes press against a rotating surface. In this system that surface is called a drum. Drum brake also has an adjuster mechanism, an emergency brake mechanism and lots of springs. The shoes are pulled away from the drum by the springs when the brakes are released.
