What type of linear actuator should I use to automate my car?
There is a wide variety of linear actuators that you can use to automate your car. Linear actuators have a significant task in opening and closing of the valves that function with the linear forces. There is a variety of the valves that you can choose from when automating your car. Here are some.
Globe valves: These are used in the trunk hinges to control the closing and opening mechanism
Control valves: These regulate the pressure in the actuators thus controlling the movement of the actuator.
Gate valves: These are valves that have a sliding effect to facilitate the movement of the hinges.
Rising stem ball valves: These are found at the rear ends of the hinges.
Types of Linear Actuators
There are two major types of linear actuators namely diaphragm piston and actuators. The diaphragm actuators comprises of up of squeezed, circular pieces of rubber on both edges of the chamber. This enables the air pressure to enter the system through both sides as it pushes the rubber to either side. There is a rod that connects the diaphragm halfway to ease its movement when the pressure is applied. A valve is linked to the rod so that the valve can experience a linear motion. This aids the opening and closing mechanism.
Piston Actuators uses a piston that can move the length of the cylinder. A rod connects the piston to the valve so that it can transmit the force. This provides room for a longer range of movement hence a higher pressure is developed than in the diaphragm actuators.
