  • Patent number: 9316193
    Abstract: Disclosed is a high-pressure pump which can easily be installed in an internal-combustion engine. Specifically disclosed is a high-pressure pump 1 provided with a mounting member 100. The mounting member 100 is fixed to a pivot 70 so as to keep such an attitude of a rocker arm 60 that the protruding end part of the pivot 70 is positioned within a concave 65a formed on a second end 65 of the rocker arm 60 and that the outer circumferential surface of the protruding end part of the pivot 70 is apart from the inner circumferential surface of the concave 65a by coming in contact with an arm body 62 of the rocker arm 60 to resist a turn of the rocker arm 60 around a roller 61 under the weight thereof, before a plunger 50 is brought into contact with a first end 64 of the rocker arm 60, and so as to come out of contact with the arm body 62 when the rocker arm 60 turns in reverse to the turn under the weight thereof, after the plunger 50 is brought into contact with the first end 64.

  • Patent number: 9057348
    Abstract: A pulsation damper mounted in a fuel chamber (23) of a high-pressure fuel pump (20) is provided with a diaphragm (11) having a flat section (11a) displaced when fuel pressure is applied thereto, a pump cover (10) for supporting the diaphragm (11), and a gas chamber (12) formed by the diaphragm (11) and the pump cover (10). Pressure pulsation occurring in the fuel chamber (23) is suppressed by displacement of the flat section (11a). The diaphragm (11) is formed in a closed-bottomed tubular shape with the flat section (11a) located at the bottom and has a projection (11b) provided to the periphery of the flat section (11a) and projecting to the side opposite to the pump cover (10). A tubular peripheral section extending from the outer periphery of the projection (11b) so as to be vertical to the flat section (11a) is fitted over the pump cover (10). The externally fitting portion of the tubular peripheral section is a joint section (11c) joined to the pump cover (10).

  • Patent number: 7797971
    Abstract: A drum washing machine has a suspension for supporting a water tub for vibration proof. The suspension includes a cylindrical bearing support, a pair of bearings fixed in the bearing support, a shaft supported on the bearings so that the shaft is linearly reciprocated, a cylindrical friction member damping an amplitude of the water tub and disposed between the bearings so as to be immovable relative to the bearing support, and a lubricant applied between the shaft and the friction member. The friction member has both ends formed with abutment slant faces having outer diameters gradually reduced toward distal ends respectively. A pair of holding members are located in the bearing support for holding the ends of the friction member. Gaps are defined between the friction member and the holding members respectively. A plurality of lubricant reservoirs are defined in the respective gaps to reserve the lubricant.
