Abstract
A dash pot which functions to control a throttle throughout its movement and also functions as a throttle return spring comprising a cylindrical body in which a guide member and associated shaft are positioned with the shaft extending externally of the body and a chamber associated with the cylinder having a diaphragm defining one wall thereof. The chamber and cylinder are filled with an incompressible fluid and an orifice is provided between the chamber and the cylinder. A spring yieldingly urges the shaft inwardly. A check valve and orifice are provided in the body to restrict the flow of fluid as the guide member is moved inwardly and permit the relatively free flow of liquid from one side of the guide member to the other as the guide member and associated shaft are moved outwardly. The end of the shaft is connected to the throttle so that when the throttle is released by the operator of the vehicle, the return velocity of the throttle to idle position is controlled throughout its movement.
