  • Patent number: 11938494
    Abstract: Turbulence of the jet ejected from the nozzle hole is suppressed. The nozzle includes a shaft body having a center axis, a liquid guide path located inside the shaft body and extending along the center axis, a liquid chamber disposed at a distal end portion of the liquid guide path the liquid chamber having a nozzle hole. The nozzle hole is located at the distal end portion of the liquid chamber, extending along the ejection axis that extends in a direction different from the center axis. The nozzle has an inlet portion having a smaller diameter toward the downstream, and a guide portion connected to the downstream of the inlet portion to guide the liquid to an opening.

  • Publication number: 20220305501
    Abstract: Provided is a nozzle for jetting liquid in an accurate direction with respect to a nozzle mounting hole. The nozzle is mounted to a nozzle holder having a nozzle mounting hole having a right cylindrical shape, an outlet port connected to the nozzle mounting hole, and a mounting internal thread. The nozzle includes: a mounting external thread disposed at a first end, and is a parallel thread that fits with the mounting internal thread; a cylindrical portion that fits in the nozzle mounting hole; a first introducing passage disposed coaxially with the cylindrical portion; a cylindrical choke portion disposed coaxially with the cylindrical portion, and a conical portion connecting the first introducing passage to the cylindrical choke portion.

  • Patent number: 9309828
    Abstract: In the start mode of a fuel supply apparatus, a subtraction value of an electric power is obtained in view of an SCV characteristic. Furthermore, a common correction value is employed as the subtraction value in order to increase an actual fuel discharge amount when the internal combustion engine is started, whereby a fuel pressure in an accumulator agrees with the target value even if an individual pump unit shows a lowest limit in the variations of the discharge amount. The common correction value is shared among the individual pump units. Even if a starting characteristic is not acquired for each of the individual supply pumps, the internal combustion engine can reliably be started.
