ABSTRACT
The present article aims to increase knowledge of stopper cylinders with return spring. A stopper cylinder with return spring works in an ambient temperature of between 253.15K and 353.15K. The stopper cylinder used in this article is only a pneumatic actuator. After introduction, the authors analyse two pneumatic circuits using stopper cylinders. The first pneumatic scheme contains the following devices: stopper cylinder (STC 1-1), throttle check valves, 5/3-way valve, air service unit and compressed air supplies. The second pneumatic circuit contains the following devices: stopper cylinders (STC 2-1 and STC 2-2), throttle valves, 5/2-way impulse valve, 3/2-way valves and compressed air supplies. Moreover, the authors study two more electro-pneumatic schemes with stopper cylinders.
Thus, the third circuit contains the following devices: stopper cylinder (STC 3-1), throttle valves, relays, 5/2-way solenoid impulse valve, pressure switch, lamp, relay counter, valves solenoid, magnetic proximity switches and compressed air supply. Finally, the fourth circuit contains the following devices: stopper cylinder (STC 4-1), throttle valve, 5/2-way solenoid valve, logic module, valves solenoid, relay and lamp.
