Tyhjiöaktiat

Tyhjiöaktiat, also known as vacuum actuators, are mechanical devices that utilize vacuum pressure to generate linear or rotary motion. They are a type of pneumatic actuator that operates on the principle of creating a pressure differential. In a typical tyhjiöaktiat, a diaphragm or piston is attached to a rod. When a vacuum is applied to one side of the diaphragm or piston, and atmospheric pressure is present on the other, the pressure difference causes the diaphragm or piston to move. This movement is then translated into useful work.

These actuators are often employed in applications where a gentle but precise actuation force is required, or where electrical power is not readily available or desirable. They can be found in various industrial settings, including automation, material handling, and packaging machinery. The simple design of tyhjiöaktiat contributes to their reliability and low maintenance requirements. Control is typically achieved by regulating the vacuum source, either by opening or closing a valve that connects the actuator to the vacuum pump or by venting the atmospheric side. The force generated is proportional to the area of the diaphragm or piston and the magnitude of the vacuum.
