  • Patent number: 4271094
    Abstract: In a vacuum motor for opening an internal combustion engine carburetor choke to a vacuum break position, a stop is engaged between the actuating diaphragm and a base member to establish the vacuum break position. The stop is formed of a malleable material which plastically deforms slightly upon engagement--and thus gradually changes the vacuum break position upon repeated engagement--to compensate for changes in engine operating characteristics over an extended period of engine operation.
