摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for attenuating fuel pump vibration propagation in a direct injection internal combustion engine.SOLUTION: A fuel injector directly injecting fuel into a combustion chamber of an engine block is supported by being suspended from a fuel rail in a fashion that avoids direct metal-to-metal contact with the engine block. The fuel injector is connected to the fuel rail by a pair of spaced-apart seals to offset force in the opposite direction in a longitudinal direction acting on the fuel injector during operation. A large-diameter fuel reservoir and/or a small-diameter orifice are provided fluidly in series between the fuel pump and the fuel injector to thereby absorb and reduce vibration resulting from fuel pump pulsation.

摘要： PROBLEM TO BE SOLVED: To provide a structure processing method reducing time of cutting works of nuclear reactor internal structures while restraining waste quantity. SOLUTION: When an old shroud 1 is primarily cut within a nuclear reactor pressure vessel 14 and is carried out to a drier separator pool 13, and secondary cutting is performed outside a reactor as a carried-out shroud 2, an aggressive water jet cutting device using alumina as a cutting agent is applied to both a primary cutting device 20 and a secondary cutting device 21 in a similar manner, and a device for collecting secondary products at the time of cutting is also applied to both the devices. Thereby, the radioactive waste quantity can be reduced, generation of rust in the nuclear reactor can be suppressed, and increase in washing work quantity can be controlled, thus reducing a whole work period.

摘要： PROBLEM TO BE SOLVED: To improve fuel consumption at the time of idling and to increase torque at the time of driving at a high speed by automatically returning the lock position of a variable valve timing mechanism to an intermediate position within a control range immediately before an engine is started. SOLUTION: In this phase variable device for controlling a phase angel being a relative position in rotational directions of a first rotary member 10 and a second rotary member 11, a power transmission mechanism which can select from among a first condition to allow the relative rotations of both the rotary members only in one direction, a second condition to allow them only in a reverse direction, and a third condition (lock condition) not to allow them in both the directions is arranged between both the rotary members. Respective conditions are changeable by a positional relationship between the relative rotational directions of the first and second rotary members, and automatic return from the first or second condition to the third condition (lock condition) can be performed based on a fluctuating torque in a direction opposite to one direction acting on the second rotary member 11 immediately before the engine is started.

摘要： PROBLEM TO BE SOLVED: To reliably and accurately convert a phase between a crankshaft and a camshaft by utilizing fluctuating torque acting on the camshaft as driving force. SOLUTION: With respect to a phase-angle control member 16 in which circumferential rotation is restrained, a vane 5 formed integrally with the camshaft is rotated together with a body 2 driven rotatively by the crankshaft. When the fluctuating torque acting on the camshaft has peaked, a communication hole 12c of a phase-angle detector 12 communicating with an advance-angle hydraulic-oil sump 8 and the communication hole 12d of the phase-angle detector 12 communicating with a retard-angle hydraulic-oil sump 9 come in agreement, in response to the direction of the fluctuating torque being at its peak, with either one of an advance-angle communication groove 16a and an retard-angle communication groove 16b respectively of a phase-angle control member 16 to allow the advance-angle hydraulic-oil sump 8 to communicate with the retard-angle hydraulic-oil sump 9. Thus, the phase of the vane 5 is converted with respect to the body 2 in the direction corresponding to the direction of the fluctuating torque being at its peak. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To automatically return a phase of a camshaft to an intermediate position by utilizing a fluctuation torque acting on the camshaft to thereby lock a valve timing controller without backlash. SOLUTION: Parallel guide portions 3a integral with a sprocket 1 and inclined guide portions 7a integral with a vane 6 are alternately arranged on the same circumference. The inclined guide portions are so formed that circumferential gaps between the inclined guide portions and the parallel guide portions become smaller in one direction of the camshaft. Wedge members 16, 17 are arranged in the respective circumferential gaps. By moving the wedge members in one direction of the camshaft, the circumferential gaps are plugged so as to secure the phase between the sprocket and the vane, thereby bringing the valve timing controller into a locked state. At that time, the wedge members having wedge angles set at sufficiently small values are energized by springs 15. The wedge members are moved in one direction of the camshaft by being energized by the springs while utilizing the positive and negative fluctuation torque acting on the camshaft so as to lock the valve timing controller. Further, the wedge members are hydraulically driven in a direction opposite to one direction of the shaft so as to release the valve timing controller from the locked state, thereby enabling control of the phase angle.
