Question

T-piece A T-piece or T-connector is a very simple component that lets us spli or divide airflow. It can be very useful if you want two cylinders to operate at the same time. AIR OUT IR OUT ARN 10 Figure 25 On circuit diagrams, the T-piece is identified by a dot. T-piece Figure Assignment 1. A delivery lorry uses a pneumatic braking system. The brakes operate when the driver presses the foot brake. Two single-acting cylinders should outstroke at the same time and press against the wheels. The pneumatic circuit is shown below. Figure 27 (a) Build and test the circuit shown. (You can use a push button, spring return 3/2 valve instead of a foot pedal.) (b) Explain the purpose of the T-piece

Answer 1

Solution:- The solution for this problem can be Explained as follows -

a) Explanation:- Buildng and testing of circuit as shown below-

---------------------------------------------------------------------

b) Explanation :- The purpose of T - piece is used to keep equal amount of preesurised air transfer to the both brakes assembly. The T piece is a device which works on principle of Pascal's Law when a pressure is exerted to inlet it gets transferred in equal amount of from the openings, and the sum of outgoing pressure is equal to incoming pressure as -

$\Rightarrow P = P_1 + P_2$
