    摘要: An apparatus and method for applying constant pressure to a plurality of pressure demanding mechanisms is disclosed. The apparatus includes a common rail, a plurality of pressure demanding mechanisms, a pressure supply source, and a plurality of branching paths. The lengths of the pressure supply path Lp, the pressure propagation path in the common rail, Lc, and the pressure branching paths, Li, are chosen so as to satisfy the following formulae, which leads to reductions in pressure fluctuations:(2n+0.5)Lp.ltoreq.Lc.ltoreq.(2n+1.5)Lp(2n+1.5)Lp.ltoreq.Li.ltoreq.(2n+2.5)Lp, where (n=0, 1, 2, . . .).

    摘要: A high pressure fuel supply pump comprises a cylinder, the upper part of which is exposed to the outside of a head cover that is a part of the engine housing, and is fixed to the head cover by means of bolts, not shown. The remaining portion of the high pressure fuel supply pump is received in an accommodation hole of the head cover. A pump cam 111 is mounted to a valve camshaft for driving a suction/exhaust valve and drives the high pressure fuel supply pump. The use of an exclusive shaft for pump driving only, a bearing member therefor, and the like is rendered unnecessary, which enables a reduction in the number of parts employed. Further, since the timing with which the pressurized fuel is discharged is controlled through the operation of a solenoid valve, the precision with which fuel injection is controlled is improved.

    摘要: A common rail delivers fuel to a fuel injection valve for injecting fuel directly into each combustion chamber of a direct injection type gasoline engine. A connected accumulator incorporates a gas-sealed type damper. A body portion of the damper can stretch and shrink by being constructed of a metallic bellows, and gas is sealed in the metallic bellows. The pressure at which the gas is initially sealed within the damper is set for 4 Mpa or more, more preferably, for 8 Mpa or more. Further, to secure suppression of a variation in normal operation fuel pressure (for example, 10-12 Mpa), the pressure at which the gas is initially sealed within the damper is set to be lower than the normal operation fuel pressure, more preferably, lower than the normal operation fuel pressure by 1 Mpa or more.

    摘要: To provide a pipe joint with which loss of rotational force added by electric tools or man power is made remarkably small, and a fastening ring can be diminished with small torque, plural fastening rings 6 vertically wound for a predetermined center angle of 360° to 480°, a guiding member 8 holding the fastening rings 6 as to restrict falling of the fastening rings 6 and allow diminishing deformation, an approximately triangular toggle member 11 disposed to protrude in a radial outer direction from the fastening rings 6 in a pipe unconnected state, and a bolt-nut connection X for moving a central peak portion of the toggle member 11 in a radial inner direction as to reduce a height dimension of the toggle member 11, are provided. The fastening ring 6 has a hitching claw portion 7 protruding in the radial outer direction, and a foot side end portion of the toggle member 11, hitching to the hitching claw portion 7, moves in a peripheral direction as to diminish the fastening ring 6 in diameter.
