    摘要: A no-return system for supplying fuel from a tank to a fuel injected internal combustion engine of an automotive vehicle in response to the fuel demand of the engine. The pump supplies more fuel than that required by the operating engine and the excess fuel is diverted from the engine by a bypass fuel pressure regulator and returned to the tank through a fluid-activatable switch movable to electrically open and closed states in response to the rate of flow of excess fuel through the switch. An electric control circuit is responsive to the state of the switch to change the magnitude of the power applied to the electric motor to change its operating speed and thereby modulate the output fuel flow rate of the pump in response to the fuel demand of the engine.
