There are various linear actuators that are used in the automation of cars. The linear actuators play an essential role in the opening and the closing of the valves that can be operated using the linear forces (actuators). There are several valves that have been adopted for the automation of cars. This paper will highlight the various types of linear actuators that have been used in car automation.
The types of valves that are essential for car automation include the globe valves, control valves, gate valves, and rising stem ball valves. The main types of linear actuators are the piston and the diaphragm. The diaphragm actuators are consisted of a round piece of rubber that is squeezed the edges between both sides of the chamber. This allows the air pressure to come through the either of the sides that push the rubber piece from one direction to the other. A certain rod is connected halfway the diaphragm to ensure that it moves as the pressure is applied. This rod is then linked to a valve stem that allows the valve to ensure that it experiences linear motion. This ensures the opening and closing of the valve.
The supply of pressure should be moderated and the thrust required should also be low. The piston actuators on the other hand use the piston that moves in the length of the cylinder. The force on the piston is conveyed through the piston rod which is directed to the valve stem. This allows for the longer travel ranges of travel and allows for higher pressure than the diaphragm actuators.
In conclusion, there are various linear actuators that are used in car automation. The piston and the diaphragm are the main types of linear actuators that are used in the automation of cars. The piston actuators allow for higher travel ranges and pressure than the diaphragm actuators.
