  • Patent number: 10961961
    Abstract: A control method of a fuel supply pump includes moving an anchor in the closing valve direction by passing a maximum drive current through the solenoid, and thereafter holding the anchor at a closing valve position by passing a holding current for keeping a closing valve state through the solenoid. The holding current is smaller than the maximum drive current. A current value of a first drive current is smaller than a current value of the holding current. A current value of a second drive current overlaps a range of the current value of the holding current.

  • Publication number: 20200393023
    Abstract: To provide a tensioner that can keep the oil pressure in an oil pressure chamber stable and consistently generate suitable reaction force and damping force to impact loads to reduce looseness in the chain and noise. A piston is set such as to partition an inner space of a plunger into an adjustment space on the front side and the oil pressure chamber on the rear side, a piston restricting member restricting the movement of the piston toward the adjustment space. An oil relief mechanism is configured to cause the piston to move forward when oil pressure in the oil pressure chamber rises so as to discharge oil inside the oil pressure chamber to the outside. The piston restricting member has an orifice function that can control the amount of discharged oil.
