Abstract (en)

[origin: WO8102630A1] A throttle control device for automobiles using internal combustion engines is mounted adjacent the accelerator pedal (21) and is connected to the engine intake vacuum by a hose (19). The vacuum operates a diaphragm (8) in the device to release a retractable spool (3) for rotation when the vacuum pressure is sufficiently high and above a predetermined level. A wire (16) wound on the spoll (3) extends from the device and is connected to one end of a spring (17). The other end of the spring (17) is connected to the accelerator pedal (21). Thus when the vacuum is above said predetermined level the accelerator pedal (21) may be depressed without any noticeable extra effort. When the vacuum falls below said level the diaphragm (8) causes locking of the spool (3) against rotation and the force of the spring (17) must be overcome to depress the accelerator pedal (21) further.
