Apparatus that applied to dentist's chairs and surgeon's tables will convert its current hydraulic or pedal movement into electric, characterized by being formed by a shield formed by four parts and two bearings mounted on a platform covered by a metal housing inside which is housed a hydraulic pump which receives pressure by means of an electric motor, printing rotary movement to a primary gear that in turn transmits it to the crankshaft gear which is attached by means of a connecting rod to the plunger that is provided with leather cups of 12 mm. Of diameter to which it prints a rectilinear movement of advance and retreat. (Machine-translation by Google Translate, not legally binding)
