Abstract

Speed limiting device for pneumatic motors characterized essentially because it is constituted by two pistons of different diameter, fixed to a common rod, each piston being in independent chambers, of which one, the smaller, receives an inflow, while, that the largest receives flow from the exhaust of a pneumatic motor, with the particularity that the piston rod, by the smaller piston, extends in a thrust whose front acts on a disc valve that coaxial to the pusher is arranged closing the outlet of a chamber independent whose entrance is derived from the inlet of the chamber of the smaller piston and whose outlet communicates with the intake of the pneumatic motor or the elements commanding said admission, a flow retarder being provided in the intake of the valve chamber, the valve of said chamber with tendency to open by means of a spring of opposite direction and less tension than another spring provided in the chamber of the larger piston, which is provided with conventional adjustment means.
