Patent ID: 8261712

Claim:
An automatic choke system for use in an internal combustion engine having a muffler and a choking mechanism that are located remotely apart from one another on the engine, the choke system comprising: a thermally responsive device; and at least one component that serves to connect, at least in part, the thermally responsive device to the choking mechanism, wherein the choke system further comprises at least one of: (a) at least one pipe for conveying at least one fluid from a first location that is at least proximate the muffler to a second location that is at least proximate the thermally responsive device, wherein either (i) the at least one fluid includes air that is fan-propelled through the at least one pipe and convectively transfers heat given off by the muffler from the first location to the second location, or (ii) the at least one pipe includes a heat pipe extending from the first location to the second location and the at least one fluid includes a fluid that has an appropriate boiling point such that, upon the heat being given off by the muffler and reaching the heat pipe, the fluid evaporates and proceeds through the heat pipe to the second location, at which the fluid condenses and gives off the heat, the heat in turn affecting the thermally responsive device; and (b) at least one physically rotatable axle that spans a majority of a distance between a fourth location and a third location that is at least proximate the choking mechanism, the at least one physically rotatable axle being comprised within the at least one component, wherein the thermally responsive device is positioned at the fourth location and the fourth location is directly adjacent to the muffler such that the heat is conductively transferred from the muffler to the thermally responsive device.
