Functional Principle The performance of work requires energy. Both devices work on the same principle that a constant current flowing through the resistor, and its changing resistance due to change in temperature, is measured as a voltage drop across it. The volume of a closed system is reduced. When pressure (boost) is applied to the top of the regulator, the diaphragm, which is attached to the bypass valve, a spring forces the diaphragm down and reduces the amount of excess fuel, this makes the fuel pumps work harder while the fuel pressure increases linearly towards the increasing boost pressure from the intake manifold. 0000007034 00000 n Types of Pressure Reducing Valves for Steam.
