A pressure regulator is disclosed for maintaining a predetermined pressure bias between two fluids. The pressure regulator comprises a body having a first fuel inlet, a second fuel inlet, a second fuel outlet and a cavity. The pressure regulator further comprises a diaphragm. One side of the diaphragm is exposed to the first fuel inlet and the opposite side of the diaphragm is exposed to the second fuel inlet and the second fuel outlet. The diaphragm is held in a fixed position relative to a control valve member which extends through the second fuel inlet to thereby move the control valve member relative to a valve seat such that a predetermined bias is maintained between the pressure of the first fuel acting on one side of said diaphragm and a pressure of the second fuel acting on the opposite side of the diaphragm. |
