ABSTRACT:
A vacuum reducer valve assembly senses the engine induction passage vacuum and delivers a reduced vacuum signal to a vacuum motor which advances the ignition timing in proportion to the vacuum signal. The vacuum reducer valve assembly has a member which decreases the difference between the induction passage vacuum and the reduced vacuum signal as atmospheric pressure decreases.
