Patent number: 11339771Abstract: 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.Type: GrantFiled: January 22, 2020Date of Patent: May 24, 2022Assignee: DENSO CORPORATIONInventor: Yuji Kitagawa
