The sealing plunger is designed to make a hard surface seal and also carries an "O"-ring to form a secondary seal. The primary function of the "O"-ring however, is to create a venturi in the normal ranges of operation to thus create a cushion area which prevents chattering, hydraulic hammering, pulsations, and the like in the fuel flow through the regulator.
