Abstract
An improved pressure regulator for use in racing and other high demand environments for use with a high pressure, high output pump. 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.
