    摘要: A housing has a compression chamber and a first passage, through which the compression chamber communicates with an accumulation chamber. A discharge valve is provided in the first passage and configured to open to supply fuel from the compression chamber to the accumulation chamber in response to increase in pressure in the compression chamber. A second passage is configured to communicate the accumulation chamber with the compression chamber via the discharge valve. A valve element allows fuel flow from the accumulation chamber to the compression chamber. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. The sidewall of the valve element and the inner wall defining the second passage therebetween define a throttle midway through the second passage for restricting fuel flow from the accumulation chamber to the compression chamber.

    摘要: A hydraulic pump includes a housing, a seat portion, and a valve element. The housing has a compression chamber and a fluid passage. The seat portion is provided midway through the fluid passage. The valve element is located between the compression chamber and the fluid passage. The valve element is a closed-end cylindrical member having a bottom portion, a cylindrical portion, and an opening end arranged in this order. The cylindrical portion is located farther away from the seat portion than the bottom portion. The valve element is seated to the seat portion at the bottom portion. A stopper substantially closes the opening end when making contact with the opening end to regulate movement of the valve element.

    摘要: A housing of a high-pressure pump defines a passage communicating with a pressurizing chamber in which fuel is pressurized. The passage has an annular engagement groove which is radially outwardly concaved on its inner wall surface. A valve body is disposed in the passage. The engaged member is disposed inside of the passage wall. A valve body engaging member is comprised of a plurality of arc-shaped plate members, which form circular shape. The valve body engaging member is inserted into the engagement groove in such a manner as to be engaged with the valve body. A C-ring is firmly in contact with the plate members and biases them toward the engagement groove.

    摘要: A movable portion is movable from a closed position, in which the movable portion is in contact with a valve element, to an opened position so as to supply fuel from a fuel portion to a compression chamber through a fuel passage. A drive control unit supplies of a small driving current, which is sufficient to maintain the movable portion at the closed position, to a coil portion so as to move the movable portion from the opened position to the closed position. The drive control unit switches the supply of the small driving current to supply of the large driving current in the course of the movement of the movable portion to the closed position by supplying the small driving current.

    摘要: A volume chamber is formed by a valve member, an inner peripheral wall of a tubular portion and a bottom portion of a stopper when the valve member is engaged with tubular portion. A communication passage communicates between the volume chamber and one of an intermediate passage of a valve body and a tertiary passage of the stopper. The communication passage is formed at a location, which is spaced from a contact surface between the tubular portion and the valve member by a first predetermined distance and is also spaced from a contact surface between the bottom portion and the first urging member by a second predetermined distance.

    摘要: A holder device has an elastic member and contact members. The elastic member is curved to extend approximately along a major arc of curvature and is elastically deformable to change a radius of curvature thereof. The contact members are circularly arranged along an inner circumferential side or an outer circumferential side of the elastic member so that each of the contact members is opposed to the elastic member in a radial direction of the elastic member. Each of the contact members has a sidewall that is opposed to the elastic member in the radial direction and is curved along an arc of curvature. A radius of curvature of the sidewall is shorter than the radius of curvature of the elastic member in its natural state.

    摘要: A fuel supply apparatus includes a movable unit, a coil, a drive circuit portion, and a drive control portion. The drive circuit portion energizes the coil with a drive electric current of a first value such that the movable unit is displaced from an opening-side position to a closing-side position. The drive circuit portion energizes the coil with the drive electric current of a second value that is smaller than the first value such that the movable unit is held at the closing-side position. The drive control portion controls the drive circuit portion to change the drive electric current from the first value to the second value while the movable unit is being displaced toward the closing-side position based on energization of the coil with the drive electric current of the first value.
