  • Patent number: 10012282
    Abstract: A flow of hydraulic oil induced by sliding movement of a piston in a cylinder is controlled by a damping force generating mechanism to generate a damping force. A flow of hydraulic oil from a casing of the damping force generating mechanism toward a reservoir is regulated by a passage groove formed on the bottom of the casing so as to be directed downward in the reservoir. Thus, the hydraulic oil is efficiently supplied to a base valve from the damping force generating mechanism even when the hydraulic oil is sucked from the reservoir into a cylinder lower chamber through a passage in the base valve during the extension stroke of a piston rod. Therefore, it is possible to suppress a sharp reduction in pressure in the lower part of the reservoir and hence possible to suppress the occurrence of aeration and to obtain stable damping force characteristics.

  • Patent number: 10010894
    Abstract: An apparatus for retarding rotation of a nozzle includes a hollow housing, a rotary shaft within the housing, a rotatable rotor on the rotary shaft free to move axially along the shaft, and a cam assembly coupling the rotor and shaft together in the housing such that rotor rotation on the shaft causes the cam assembly to displace the rotor axially on the shaft in a first direction. A set of springs on the shaft biases the rotor in a second direction opposite the first direction on the shaft. Finally, a viscous fluid disposed between the rotor and the housing generates a drag on rotor rotation with the shaft. Relative rotation of the rotor with respect to the shaft in conjunction with a variable gap between the rotor and housing are used to slow and thus control rotary nozzle speed.
