ABSTRACT:
A vacuum-operated, pressure-responsive valve is adapted for connection to the intake manifold of an internal combustion engine for monitoring supplemental airflow to the engine, the improvement of the present device providing precise adjustment of the supplemental airflow/intake manifold pressure relationship. An air cylinder, a pressure-responsive piston/valve mounted therein, a threadably mounted axially extending stem and valve-biasing spring, and a resiliently deflectable plate are assembled and cofunction to provide precision click stop adjustment of the supplemental airflow/engine vacuum relationship.
