摘要： High-response and high-power electromagnetically driven flow rate control valve with flange portion forming an attracting surface on an anchor, a first peripheral surface portion having a diameter smaller than the flange portion, and a cylindrical non-magnetic area opposing an outer peripheral surface of the flange portion with a third clearance interposed therebetween are provided, and a first fluid trap portion communicating with the back pressure chamber via the third clearance is provided. When the diameter of the flange portion is enlarged in order to enlarge the cross-sectional area of the attracting surface, fuel that is displaced by the anchor is increased, but is partly absorbed in the first fluid trap portion, so that the fuel passing through the fuel channel does not increase in comparison with fuel before the diameter of the flange portion is enlarged. Accordingly, the cross-sectional area of the attracting surface may be enlarged.

摘要： In a high pressure fuel supply pump for transmitting rotation of a cam to a reciprocating plunger via a tappet and a retainer, a diametric force acting on the plunger is reduced. The pump includes the retainer disposed on the plunger and a return spring exerting an urging force on the retainer in a direction of the tappet. A clearance between a plunger leading end and a tappet bottom surface opposed thereto is set to be greater than a clearance between a retainer bottom surface and the tappet bottom surface opposed thereto, and a clearance between a retainer inside diameter section and a plunger peripheral surface section opposed thereto is set to be greater than a clearance between a retainer outside diameter section and a tappet inner wall opposed thereto.

摘要： In an electromagnetically controlled inlet valve actuator provided to a high pressure fuel pump, an impinging sound which is generated at the time of operating the mechanism is reduced. In a high pressure fuel pump provided with an electromagnetically controlled inlet valve (operated by way of a plunger rod), a current supply period includes a 1st current supply period for performing an operation of attracting the plunger rod in a valve closing direction, a 2nd current supply period for alleviating a speed at which the plunger rod moves in a valve opening direction, and a limited current supply period disposed between the 1st current supply period and the 2nd current supply period in the form of spanning a pump top dead center.

摘要： A high-pressure fuel supply pump which has no probability of discontinuity of a thin film of fuel at a sliding portion even when the fuel is not needed to be compressed to a high pressure is obtained. Two low-pressure fuel ports are provided on the high-pressure fuel supply pump in addition to a high-pressure discharge port to a high-pressure fuel capacity chamber. One of the two low-pressure fuel ports is connected to a low-pressure fuel capacity chamber and remaining one is connected to a low-pressure fuel supply pump. Accordingly, the interior of the high-pressure fuel supply pump is always filled with fresh fuel even in a mode in which a high-pressure fuel injecting valve does not inject fuel and only a low-pressure fuel injection valve injects fuel, so that a temperature rise of a plunger and a cylinder is prevented and locking of the plunger and the cylinder can be prevented.
