摘要： PROBLEM TO BE SOLVED: To stabilize a combustion state by preventing the occurrence of a trouble, such as a misfire, occasioned by negative pressure ensuring operation, in a negative pressure control device for an internal combustion engine to ensure a negative pressure for a brake booster. SOLUTION: A fuel injection valve 11 is arranged at the peripheral part of the inner wall surface of the cylinder head 4 of an engine 1. Fuel is injected directly in a cylinder 1a from the fuel injection valve 11. A negative pressure in a suction duct 20 positioned downstream from a throttle valve 23 is introduced in a brake booster 71 through a connection piping 73. An electronic control unit (ECU) 30 increases a negative pressure in a suction duct 20 by executing control of closing of the throttle valve 23 when a value obtained by subtracting a brake booster pressure detected by a pressure sensor 63 from an atmosphere pressure is decreased to a value lower than a given value. In this case, the ECU 30 controls the EGR valve 53 of an exhaust gas recirculation (EGR) mechanism 51 to a full closed state and recirculation of exhaust by the mechanism 51 is stopped.

摘要： PROBLEM TO BE SOLVED: To reliably perform sufficient assist control on brake operation on and after the second time by forming a vacuum valve and a breather valve as an electrically openable-closable solenoid valve, and driving the solenoid valve on the basis of output by detecting stepping-down of a brake pedal on the basis of a pedal stroke. SOLUTION: A different pressure chamber 1 is communicated with a vaccum chamber 2, and when an opening part of a negative pressure passage 11 is opened so as to separate from a valve element 3 as a vacuum valve, negative pressure from the vacuum chamber 2 is introduced. The different pressure chamber 1 is also communicated with an external part, and when it is opened so as to separate from a valve seat 12 in which an atmospheric pressure passage part 4 is arranged, atmospheric pressure is introduced. A control device inputs detecting information of a sensor, and outputs a control signal to drive a solenoid 5 of a vaccum booster 25. The vaccum booster 25 has a power piston 10, and a load equivalent to boosting power is transmitted to a push rod 8 and a master cylinder 26 by differential pressure generated between the vaccum chamber 2 and the different pressure chamber 1. Therefore, when vehicle speed is fast and urgency is high, control at second stepping-down time can be performed.

摘要： PROBLEM TO BE SOLVED: To provide a brake booster in which occurrence of engine stalling can be prevented in the case of an opening trouble of a valve such as a solenoid valve. SOLUTION: In a brake booster 1, a pressure changing chamber 6 and a negative pressure chamber 7 parted by a diaphragm are provided, and a first mechanical valve 8, a second mechanical valve 9, a directional control valve (solenoid valve) 11, and a third mechanical valve 12 are disposed for adjusting pressure in both chambers 6, 7. The directional control valve 11 of them is a three-way valve to change three-direction tubular ways at two positions from the open air side to reach the negative pressure chamber 7 and the pressure changing chamber 6. The third mechanical valve 12 is provided between the negative pressure chamber 7 and a check valve 19 in a tubular way 18 communicating the negative pressure chamber 7 with the engine side. The third mechanical valve 12 is a selector valve mechanically changeable between two positions of a communication condition and a restriction condition in accordance with differential pressure between pressure in the negative pressure chamber 7 and intake negative pressure on the engine side.

摘要： PROBLEM TO BE SOLVED: To function it as an antiskid braking device or even automatic braking device at the time required by providing a control unit which opens or closes those of first, second and third on-off valves separately at the time required. SOLUTION: When a brake pedal is trodden from an illustrated un-operating state, atmospheric air is taken into a bellows chamber C, and this air is taken into a transformer chamber B via a first passage 43. With this, differential pressure is produced between a constant pressure chamber A and this transformer chamber B at the outside of the bellows chamber C and therefore a brake booster 2 is operated as in the past. Next, a solenoid on-off valve 6 is closed by a control unit 11 from this operating state and simultaneously when another solenoid on-off valve 7 is opened, the atmospheric air in the transformer chamber B is exhausted to the outside of the transformer chamber B via a second passage 44 and the constant pressure chamber A at the outside of the bellows chamber C, and thus it will function as an antiskid braking device. In addition, the solenoid on-off valve 6 is closed by the control unit 11 from an illustrated un-operating state, and when a solenoid on-off valve 8 is opened, the brake booster 2 operates even if the brake pedal is not trodden.
