Abstract
An improved governor device for a telephone dial which includes a rectangular hexahedral chamber provided with a rack engaged with a pinion and a cylindrical chamber provided with a piston secured to said rack at one end and having a valve system. The two chambers are filled up with a certain liquid such as silicone oil in order to afford a resistance to the piston. The piston can move either way upon dialing and at this time due to the resistance from the liquid the piston can reciprocate without any noise within a certain interval.
