SM valves 50FL, 50FR are in an open position which opens a line when electric power is OFF and are switched to a closed position when energized by a brake controller 30. These SM valves 50FL, 50FR are formed integrally with the pressure regulation valves (here, the closed position refers to the position (pressure regulation position) where the lines are opened when pressure applied from W/C 2FL, 2FR side is over a predetermined value and the SM valves function as pressure regulation valves). Also, restrictions 50FLS, 50FRS are provided across a switching region where the opening and closing of the SM valve 50FL, 50FR is executed in the M/C 234 side to apply pressure between the restrictions 50FLS, 50FRS and the switching region. In this way, aeration which occurs when high pressure fluid is returned to the M/C side is prevented and thus, vapor locks can be prevented.

A fuel injection system for internal combustion engine of the spark ignition type is provided with a fuel metering apparatus including a fuel flow control orifice having an opening area or flow section which is varied in dependence upon a flow rate of intake air inducted into the engine. A fuel metered through the fuel metering apparatus is distributed by a distributing plate driven synchronously with the rate of revolutions of the engine at a predetermined rate and supplied intermittently and sequentially to individual cylinders of the engine through associated fuel injection valves by means of a pressure feeding apparatus such as plungers which are provided in number equal to that of the cylinder and driven synchronously with the revolution of the internal combustion engine.
