Reciprocating motion of a single and a double acting actuators using 5/3 DCV.
9
Speed control circuits.
10
Automatic to & fro motion of a pneumatic linear actuator
11
Sequencing circuit
12

13
Students should build up the above circuits on computer using software and simulate the flow of fluid during the operation. Afterwards, they themselves can physically connect the circuit on the hydraulic/pneumatic trainer and run the circuit.

Open Ended Problem
Student can be given an application of a power transmission system for which they can evaluate the functional requirements and design appropriate circuit.They must identify the components, and relevant parameters. The application must involve use of hydraulics/pneumatics and/or combinations of different power transmission systems.
