Dierre New Power
The cylinder mechanism is based on the "desmodromic" concept, which is derived from the Greek word for "forced path."
In the absence of the key the combination gorges are in a chaotic (random) position, any movement or vibration of the cylinder can cause the gorges to move in an unpredictable manner.
The coding of the key corresponds to the shape of the track carved on the key.
When the key is inserted into the cylinder, the gorges assume the only allowed position that corresponds to the key encoding.
The technique known as "bumping" (a widespread system of illegal cylinder opening) is not applicable to the NEW POWER cylinder, thanks to the desmodromic encryption system.
