摘要： A fuel supply system for a direct injection engine which has a variable capacity single cylinder plunger pump and two fuel rails. Offices are disposed at the upstream side inlets of both fuel rails, respectively. At the opposite sides to the inlet sides, the fuel rails are interconnected with each other by a connecting pipe. Using this fuel supply system, it is possible to increase a characterisitic frquency of the fuel columns, and to stabilize, suppress, and smooth out pressure pulsation in the fuel rails, thereby reducing uneven fuel injections into the cylinders. The system may have a cam which drives a plunger of a high pressure fuel pump to reciprocate once for every two combustions in two engine cylinders.

摘要： A high-pressure fuel supply pump includes a compression chamber, a plunger reciprocating in the compression chamber for pressurizing fuel in the compression chamber, a discharge valve for discharging pressurized fuel from the compression chamber to a high-pressure fuel passage of a high-pressure fuel supply system for supplying high-pressure fuel to an internal combustion engine, and a first solenoid actuated valve for connecting and disconnecting a first low-pressure fuel passage and the compression chamber. The first solenoid actuated valve is biased by a first biasing member in a closing direction of the first solenoid actuated valve, and is opened or kept open against the biasing force of the first biasing member, when the first solenoid actuated valve is energized. The high pressure fuel supply pump further includes a second solenoid actuated valve for connecting and disconnecting a second low-pressure fuel passage and the compression chamber.

摘要： In order to provide a method for high volume and high pressure operation of a variable delivery type single cylinder plunger pump, the displacement of the piezoelectric element 20 is magnified by a hydraulic displacement magnifying mechanism comprising a large-diameter bellows 204, a small diameter bellows 202 and working fluid 208, and an engaging member 201 is displaced to control the time interval of opening and closing the intake valve 5. The large-diameter bellows 204 is used at all times in the state compressed in the direction of displacement transfer, thereby ensuring that the pressure of the working fluid 208 is maintained at a positive value to prevent vapor from being generated. The thermal expansion of a casing 23 is selected in such a way that the total thermal expansion of the piezoelectric element 200 and hydraulic displacement magnifying mechanism in the direction of displacement transfer is approximately the same as the thermal expansion of the casing 23, whereby highly efficient driving is provided.

摘要： A high-pressure fuel supply pump mounted with a discharge valve that can reduce an influence of noise caused by a valve body-circumferential flow and a discharge valve unit used therein. The high-pressure fuel supply pump includes a discharge valve (8) which is a non-return valve between a pressurizing chamber (11) and a discharge port (13). The discharge valve (8) includes a valve body housing (8d), a discharge valve spring (8c), a valve body (8b) and a seat member (8a). The discharge valve (8) is a flat valve. When the valve is opened, a flow of fuel moving from the pressurizing chamber and axially colliding with the valve body is radially distributed in the radial direction of the valve body to become a flow directly moving the discharge ports and a flow colliding with an inner wall of the valve body housing before moving toward the discharge ports and then in a circumferential direction of the valve body. The discharge valve (8) is provided with a liquid damper chamber defined between an outer circumference of the seat member (8a) and an outer circumference of the valve body (8d) and an inner circumference of the valve body housing (8d) to face the flow in the circumferential direction. The liquid damper chamber includes first, second and third tubular passages (503A, 503B, 503C).

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.
