Condition response differential vacuum regulator and method of making the same

摘要

A differential vacuum regulator having an input chamber and an output chamber and a control arrangement for providing an output signal in the output chamber that has a constant differential value from the value of an input signal in the input chamber, the regulator having a condition responsive unit that is independent from the value of the input signal and is adapted for varying the differential value in relation to the condition being sensed by the condition responsive unit.
