  • Publication number: 20190170102
    Abstract: An object of the invention is to achieve sufficient atomization, while preventing a spray from spreading. A fuel injection valve includes a plurality of swirl fuel injection passages. Each of the swirl fuel injection passages includes a swirl chamber, a swirl chamber introduction passage, and an orifice and imparts a swirling force to fuel to thereby inject the fuel outside. A rectangular coordinate system is imagined on an imaginary plane. The rectangular coordinate system has a center of an inlet opening surface of the orifice as an origin and has an X-axis extending in parallel with a centerline of the swirl chamber introduction passage and being positive in a direction from an upstream side toward a downstream side of the swirl chamber introduction passage and a Y-axis extending perpendicularly to the X-axis and being positive in a direction away from the centerline.

  • Patent number: 5836246
    Abstract: A printing press includes a plurality of cylinders, a main drive system, an auxiliary drive system, and a torsion bar. The plurality of cylinders are arranged in parallel to each other in an axial direction and includes a plate cylinder. The main drive system is constituted by a plurality of drive gears that drive the plurality of cylinders by transmitting rotation of a drive unit thereto. The auxiliary drive system is connected to the main drive system and includes at least one drive gear that drives the plate cylinder by transmitting rotation of the main drive system thereto. The torsion bar applies a braking force to the plate cylinder through the auxiliary drive system in a direction opposite to that of rotation of the main drive system.

  • Patent number: 5289773
    Abstract: An object of this invention is to provide an apparatus capable of easily and accurately mounting a plate to a predetermined position of the circumferential surface of a plate cylinder. A safety cover for covering the circumferential surface of a plate cylinder is suspended and is vertically opened/closed by a hydraulic cylinder. A plate reception member and a plate holder are mounted on the safety cover to hold a plate to be mounted on the plate cylinder. In mounting of the plate, the safety cover is opened, and the lower end of the plate is removed from the plate holder and is inserted into a plate lockup device mounted in the plate cylinder. At this time, notches formed at the lower end of the plate are respectively engaged with reference pins formed on the plate lockup device. When the upper end of the plate is inserted into the plate press member, the notches of the plate are fitted on the reference pins by the weight of the plate and the behavior of the plate press member.
