| Hydraulic and pneumatic fluid systems consist 1 | a pump (sometimes including cylinders and pistons) forces fluids
through a system
• conductors (tubing, hoses, or pipes) provide a pathway to carry
the fluid
🗑
|

| Hydraulic and pneumatic fluid systems consist 2 | valves keep the fluid moving in the desired direction at the desired
time
• a pressure gauge monitors pressure within the system
Each component has its own job to do
🗑
