1. An over-acceleration protection device on an internal combustion engine (ICE) or turbines, comprising
a first gear wheel which is connected to and transmits rotational motion of said first gear wheel to a second gear wheel, the second gear wheel having a first conical gear connected below said second gear wheel and rotatably secured to a pin of an existing fitting, wherein said pin is fixedly secured to said existing fitting and the first conical gear is rotatably secured to the pin using a first allen type screw;
a bushing having a second conical gear integrally secured thereto, a bushing hole along a free end of the bushing, and a plunger hole along a recess opposite to the free end, wherein the bushing is inserted into and rotatably secured within a hole of said existing fitting so that the hole of said existing fitting and the bushing hole of said bushing are aligned with each other;
a washer secured within the recess of said bushing using a plurality of second allen type screws, said washer having a female helical thread in a center of the washer;
a counterweight carrier having a male helical thread and a plurality of counterweights permanently connected thereon using a plurality of pins and a plurality of safety clips said counterweight carrier also carries, the counterweight carrier secured to the bushing via the male helical thread fastening to the female helical thread;
a longitudinally extending plunger valve having a piston portion along a first free end, the plunger valve extending through the counterweight carrier and the bushing such that the piston portion fully covers the bushing hole;
a lid secured to said bushing using a set of four screws, whereby the lid and said bushing encase said counterweight carrier, while at the same time at least one counterweight of said plurality of counterweights of the counterweight carrier extends out of each of two peripheral openings of said lid as the protection device rotates, wherein two screws of the set of four screws each extend through a corresponding peripheral hole of the two peripheral holes of the lid, and a spacer and a needle bearing are each coaxially secured about each of the two screws in the corresponding peripheral hole such that the needle bearing is secured directly around the spacer which is secured directly around a corresponding screw, each counterweight of said plurality of counterweights resting firmly on the needle bearing;
a thrust bearing mounted on said counterweight carrier and on a pressure spring, a pressure of said pressure spring adjusted by a position of an adjusting screw, wherein said adjusting screw is secured by an adjusting screw nut, and wherein the protection device relies on a centrifugal force effect such that the protection device is activated when a force causes said counterweights to rotate during operation of the ICE or the protection device is uncontrolled and within a limit of over-acceleration revolutions.
