Abstract
A throttle stop assembly is shown having a body or housing containing a diaphragm therein which serves to define within such housing a relatively high pressure or atmospheric chamber at one side of the diaphragm and a relatively low pressure or vacuum chamber at the other side of the diaphragm; the vacuum chamber is provided with at least one interior wall against which the diaphragm member is brought when a first magnitude of vacuum is admitted to the vacuum chamber as to thereby correspondingly position a related movable throttle stop member; when a second magnitude of vacuum is admitted to the vacuum chamber a portion of the diaphragm is moved further toward and operatively against a second wall or abutment as to thereby again correspondingly position the related movable throttle stop member.
