摘要： PROBLEM TO BE SOLVED: To provide a normal close type high pressure pump having improved responsiveness at high speed rotation. SOLUTION: In the normal close type high pressure pump, a needle 61 installed integrally with a movable core 53 abuts against a valve member 21 by biasing force of a needle spring 56 when an electromagnetic actuator 50 is not energized and advances by electromagnetic attraction force upon energization. The needle 61 has a flange portion 611 having the outer diameter slightly smaller than the inner diameter of a valve cylindrical part 232. When the pressure in a pressurization chamber 95 is reduced and the valve member 21 is opened in a suction process at high speed rotation, fuel flows through a throttle flow passage 931 in a gap between the flange portion 611 and the valve cylindrical part 232 to generate a differential pressure, and the advancing operation of the needle 61 is assisted by the differential pressure. With this, the valve member 21 can be opened surely and the responsiveness at high speed rotation is improved. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high pressure fuel pump not causing the enlargement of an electromagnetic drive part by reducing a force required by an elastic member for keeping a valve member separate from a valve seat. SOLUTION: When the valve member 41 is separated from a valve seat 32, the movement of the valve member 41 is restricted by abutting on the stopper 42. A cylindrical part 45 of the valve member 41 is closed by the stopper on an end at the opposite side of a bottom 44. Consequently, fuel of which the pressure rises in a pressurizing chamber 113 does not flow in the cylindrical part 45 when fuel is returned to a fuel chamber 16 from the pressurized chamber 113. A collision of fuel with the bottom 44 of the valve member 41 is thereby mitigated and the valve member 41 is not pushed in to a valve seat 32 side by the flow of fuel. As a result, a pressing force of a spring 56 pressing the valve member 41 to keep the valve member 41 separate form the valve seat 32 is reduced, and the enlargement of the spring 50 and the electromagnetic drive part 50 can be inhibited.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive fuel injection valve capable of finely adjusting fuel injection quantity even if coil electrifying period is short without causing deterioration of magnetic characteristic.
SOLUTION: When electrifying a coil 32, a movable core 35 integrated with a needle 24 is moved at the predetermined distance, and brought in contact with a sliding pipe 60. When the movable core 35 is moved toward a fixed core 33 side, the movable core 35 is pushed to an injection hole 23 side by a first spring 41, and pushed by a second spring 42 when the movable core 35 is brought in contact with the sliding pipe 60. With this structure, the force to be applied to the movable core 35 is small in the initial time of the movement, and increased on the way of the movement. Quick movement of the needle 24 and the movable core 35 integrated with each other can be secured in the initial time of the movement, and moving speed of the movable core 35 is lowered before the movable core 35 collides with the fixed core 33. As a result, bound of the movable core 35 collided with the fixed core 33 is reduced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve accurately controlling fuel injection quantity while inhibiting increase of the number of components and increase of assembly man-hour.
SOLUTION: A seat part 50 supporting a spring 45 is installed on an end part in an injection hole 23 side of a cylinder member 11. A separate member for retaining attitude of the spring 45, therefore, is not required and number of components can be reduced. The seat part 50 is formed as one body with the cylinder body 11 and is formed by bending a part of the cylinder member 11. Consequently, a structure can be simplified and working man-hour can be reduced. Also, a movable core 40 and a needle 24 can relatively move in an axial direction, and pressing forces of a spring 37 and a spring 45 are different. Consequently, bound of a needle 24 associated with collision of a movable core 40 and the fixed core 33 and bound of the needle 24 associated with collision of the needle 24 and a nozzle body can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply device capable of inhibiting operation noise generated when a movable part is moved to a close side position.
SOLUTION: Electricity is carried to a coil 65 with prescribed drive current Iv. First, second, third, . . . , n-th drive signal are at high level at time T1 in addition to base drive signal for that. Consequently, electricity is carried with the drive current Iv from time T2 to T4. Consequently, moving speed of a needle 64 (gradient indicated by a symbol K) can be limited by setting drive current Iv to appropriate value. Namely, soft landing of the needle 64 can be materialized. Set of drive current Iv is done by learning control. Namely, drive current is gradually reduced, it is determined if fuel pressure drops or not, and learning control is executed.

摘要： PROBLEM TO BE SOLVED: To provide a high-pressure pump in which the drive performance of an electromagnetic drive part for controlling a discharge amount is improved.SOLUTION: A housing body 11 includes a pressurization chamber 113 for pressurizing fuel and a fuel passage 100 for introducing the fuel to the pressurization chamber 113. A valve member 40 shuts off and allows a fuel flow in the fuel passage 100 by getting seated on and leaving from a valve seat 34 of a valve body 30 provided in the fuel passage 100. A stopper 50 regulates movement of the valve member 40 in a valve opening direction by contacting with the valve member 40. The outer diameter of a surface of the valve member 40 where a contact part with the stopper is formed is smaller than the outer diameter of a surface of the stopper 50 where a contact part with the valve member is formed. Thus, the stopper 50 inhibits the dynamic pressure of the fuel flow from acting on the valve member 40. Accordingly, a load on a second spring 22 for biasing the valve member 40 in the valve opening direction can be decreased, and an electric current value required to operate an electromagnetic drive part 70 can be reduced.

摘要： PROBLEM TO BE SOLVED: To reduce an estimated error of an operation amount in a sensorless angle detector which calculates the operation amount on the basis of a current value of a current flowing in an electric motor.SOLUTION: Calculation of an operation amount x is canceled until it is detected "that an inrush current flowing in an electric motor is turned into descending from rising", and the operation amount x is calculated on the basis of a current value of the current flowing in an electric motor after it is detected "that the inrush current flowing in the electric motor is turned into descending from rising". Thereby, "time lag due to nonrotation during a period from a conduction start T0 to a motor rotation start T1" is canceled, and the operation amount x can be obtained from "a current value after the motor rotation start T1". Thus, a measurement error during the period from the conduction start T0 to the motor rotation start T1 can be eliminated, and an estimation error of the operation amount x can be reduced.
