Abstract
A pressure reducer valve includes a first chamber having a first spring and a first volume for receiving an output fluid having an actual output pressure that equals the desired output pressure in response to the pressure reducer valve achieving equilibrium and a second chamber having a second spring and a second volume for receiving a return fluid having a return pressure that is less than the desired output pressure and the input pressure of an input fluid. The pressure reducer valve further includes a main shaft exposed to the first spring and the output fluid from the first chamber and the second spring and the return fluid from the second chamber such that the main shaft may move relative to the first chamber and the second chamber based on forces applied by the first spring, the output fluid, the second spring, and the return fluid.
