摘要： To provide a small-sized and lightweight gearshift operating device that is capable of performing a gearshift operation in a short time at low power consumption, a guide slit having a plurality of slits 41 parallel with the shift fork shafts and a plurality of slant slits 42 concentrated to a neutral point 43 from them is employed to guide a follower 33. The follower 33 is operated along the guide slit, thus the number of times of starting and stopping operations of the motor for the shift operation is reduced, and the load of the actuator for the selection operation is reduced.

摘要： To reduce collision noise created by the operation of an electromagnetic suction valve provided on a high pressure fuel supply pump. In the present invention, in order to achieve the above object, the mass of a member which collides by magnetic attractive force is reduced to reduce the noise to be generated. The thus configured present invention provides the following advantageous effects. The noise generated when a core and an anchor collide with each other by magnetic attractive force depends on the magnitude of the kinetic energy of a moving element. The kinetic energy to be consumed in the collision is only the kinetic energy of the anchor. The kinetic energy of a rod, being absorbed by a spring, does not contribute to the noise; thus, the energy when the anchor and the core collide with each other can be reduced, whereby the noise to be created can be reduced.

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： It is an object of the present invention to improve responsiveness in valve opening and valve closing of an electromagnetically driven intake valve unit in which a valve is provided on a pressurizing chamber side of a valve seat. The valve includes an annular abutting surface that abuts the valve seat to shut off a fuel intake passage and a bottomed cylindrical part provided at an inner peripheral part of the annular abutting surface. The bottomed cylindrical part is inserted into a fuel introduction hole formed in the valve housing inside the valve seat, and the outer surface of an end part of the bottomed cylindrical part is exposed to fuel in a low pressure fuel chamber provided upstream of the fuel introduction hole.

摘要： The objective of the present invention is to dampen operating sounds of an electromagnetic drive mechanism used for a variable displacement to reduce an individual difference depending on apparatus due to the control mechanism in a high-pressure fuel supply pump change over time or installation tolerance.To achieve the above objective, the present invention is configured such that before the electromagnetic drive mechanism supplies a drive force to a plunger which is electromagnetically driven by the electromagnetic drive mechanism, another displacement force situates the plunger in a specific position. When compared to an occasion where the plunger is displaced all strokes by a magnetic biasing force, the above configuration is able to reduce the force of impact on a member (for example, valve body) mounted to the plunger and a restricting member, thereby damping the collision noise. Furthermore, since an extra member, such as a damping member, is not required, individual difference depending on apparatus do not easily occur.

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： The present invention relates to a method and an apparatus for controlling a high-pressure fuel supply pump configured to supply pressurized fuel to an internal combustion engine, with a solenoid-actuated intake valve being configured to be biased into a first direction towards a first stop position of the intake valve by means of a biasing force and being configured to be displaced against the biasing force into a second direction opposite to the first direction towards a second stop position of the intake valve by means of magnetic force and to be kept at the second stop position by means of magnetic force. The method includes applying control current to the solenoid-actuated intake valve for displacing the intake valve into the second direction to the second stop position and for keeping the intake valve at the second stop position during a first time period by means of magnetic force.
