Abstract
The fuel system includes a fuel tank for supplying fuel to a fuel rail having fuel injectors and a fuel pressure regulator for regulating the pressure of the fuel supplied to the fuel rail to a predetermined pressure. The pressure regulator includes a spring-biased ball movable toward and away from a valve seat with an intervening flow channel director. The flow channel director is sized to provide a substantially constant regulated pressure over a flow range typical for automotive engine use, i.e., a pressure of 350-430 kPa over a flow range of 20-50 kg/hr. The pressure regulator provides the predetermined regulated pressure without a movable diaphragm dividing the regulator into flow and non-flow chambers on opposite sides of the diaphragm.
