Abstract
An altitude compensation device for internal combustion engines such as automotive engines. The device has a first diaphragm device and a second diaphragm device which are provided with a first diaphragm chamber and a second diaphragm chamber defined by a first diaphragm and a second diaphragm, respectively. A choke lever connected to a choke valve is fixed to the first diaphragm while a stopper for limiting the opening of the choke valve is provided on the second diaphragm device. A first communication passage provides a communication between the first diaphragm chamber and the intake passage of the engine so as to transmit the intake vacuum to the first diaphragm chamber to drive the choke valve in such a direction as to open the choke valve. A second communication passage provides a communication between the intake passage and the second diaphragm chamber to transmit the intake vacuum thereby to move the stopper in such a direction as to afford a larger opening of the choke valve. An air bleed valve is disposed in the second communication passage to selectively bring the latter into communication with the atmosphere.
