Compensating valve system for controlling adjustable emulsifying orifice

摘要

A fuel system is described for homogenizing a liquid fuel component and a fresh water component by an adjustable emulsifying orifice. The downstream pressure of the homogenized fuel and water components at the suction side of a feed pump is monitored and controlled by a compensating valve which continuously and automatically adjusts the orifice size within the adjustable emulsifying orifice. The compensating valve is arranged in fluid communication with the suction side of the pump to be operative in response to changes in the pressure. The compensating valve is of the diaphragm type having an underlying piston provided with piston rings which prevent fluid communication between the suction side of the pump and its internal connecting assembly in the event of rupture of the diaphragm.
