Abstract
An altitude compensation device for automobile engines or the like having a bellows adapted to detect the altitude and a plurality of valve mechanisms adapted to be actuated by the expansion or contraction of the bellows to adjust respective compensation air. The device has a disc mounted in the body of the device for free up and downward movement keeping a horizontal posture. The disc is carried by the bellows making a point contact with the central portion of the upper face of the bellows, so that it is almost free from the tilting of the bellows attributable to a vibration or the like. The valve mechanisms are operatively supported by the disc so as to be actuated uniformly by the bellows through the medium of the disc. Also, means are provided for adjusting the valve mechanisms independently of one another.
