How Piezo Injectors Work. The heart of a Piezo (short for piezoelectric) injector is the piezo crystal. When electricity is applied to the crystal, it rapidly expands, thus making it suitable to act as the actuator in a diesel fuel injector.ressurized fuel is delivered to the top of this needle as well, the force of which keeps the needle closed. When the piezo crystal is energized, a valve at the top of the needle opens, allowing the pressurized fuel at the top of the needle to return to the tank through the return line.
How the Continuous Rotation MOVA globe works. The MOVA globe consists of two spheres, an inner sphere containing the drive mechanism and which is encapsulated inside a fluid filled transparent outer sphere.The inner globe is suspended in an almost friction free environment, much like the earth itself.he fluid in your MOVA globe is injected through a small fill hole that is subsequently sealed. Please orient the outer sphere so the sealed fill hole is located at the South Pole. This will hide the fill hole so it will not detract from your viewing experience. Your MOVA Globe is designed for indoor use.
