摘要： An enrichment device for a charge forming system for an internal combustion engine that is responsive to induction system pressure for effecting a pumping action to draw fluid in when the engine is operating in a steady state condition and to discharge fluid for enrichment when the engine is being accelerated. The system includes a series of interrelated pressure sensing chambers for controlling the operation of the pump to avoid fluctuations during small variations in induction system pressure but to permit rapid and immediate pumping action upon sudden pressure changes.
