  • Patent number: 11339771
    Abstract: A fuel injection pump includes a cylinder formed with a passage of fuel, a plunger, and a swirl flow generating par. The plunger slides along an inner wall of a sliding hole located in the cylinder and reciprocates between an uppermost point and a lowermost point to pressurize the fuel in a pressurizing chamber placed at an end of the sliding hole at a highest point. The plunger is movable downward to cause the pressurizing chamber to inhale the fuel from an intake passage in a fuel suction stroke. The intake passage is communicated to the pressurizing chamber at a lateral side of a plunger axis that is an axis of the plunger in a sliding direction. The swirl flow generating part guides the fuel to form a swirl flow around the plunger axis in the fuel suction stroke.

  • Patent number: 9774104
    Abstract: A ground connection structure includes a stud bolt (11) standing on a ground surface (10A), and a non-circular rotation stopping portion (12) is formed on a base part of the stud bolt (11). A ground terminal fitting (20) is to be connected conductively to the ground surface (10). The ground terminal fitting (20) has a non-circular rotation stopping hole (25) that is fit to the rotation stopping portion (12) with relative rotation restricted. Resilient contact pieces (27) extend in an axial direction of the stud bolt (11) from an edge of the rotation stopping hole (25). A nut (15) is screwed onto the stud bolt (11) and causes the resilient contact pieces (27) to be deflected resiliently between the nut (15) and the ground surface (10).
