    Abstract: A variable flow check valve device is proposed comprising an inlet connected with a first pressure fluid reservoir, an outlet connected with a second pressure fluid reservoir, which is separate and/or separable from the first pressure fluid reservoir, a check valve closing member configured to open and to close the outlet in response to a pressure difference of the pressure fluid on opposite sides of the check valve closing member, and a spool valve with a movable spool disposed in a flow path of the pressure fluid extending from the inlet to the outlet, the spool valve forming a variable orifice within the flow path of the pressure fluid, wherein the variable flow check valve device further comprises a force balancing unit disposed in the flow path of the pressure fluid and configured to create a balancing force to at least partially counteract a force acting on the spool when the pressure fluid passes the at least partially opened spool valve.

    Abstract: A suspension system of an associated vehicle. The suspension system comprises an outer reservoir tube extending along an axis between a first end and a second end and defining a chamber. A piston assembly is at least partially located in the chamber. The piston assembly includes a piston rod and a piston head. A solenoid assembly is connected to the piston rod. The solenoid assembly comprises a core including a core head and a core body. A spool extends about the core body and defines a space. A coil is wrapped around the spool within the space. An induction plate is at least partially located between the spool and the core head. As the input current is modulated the induction plate promotes the induction of eddy currents opposing the field induction attenuating the force ripples of the magnetic field buildup and decay.

    Abstract: A damping unit of a shock absorber has: a damping valve provided in a second fluid passage, the damping valve being configured to impart variable resistance to a flow of working oil passing therethrough depending on positions; a bypass passage connected to the second fluid passage so as to bypass the damping valve; a solenoid valve configured to control the flow of the working oil in the bypass passage guided to the damping valve as a pilot pressure for switching the positions of the damping valve; a bottom-side restrictor portion configured to impart resistance to the flow of the working oil guided from the second fluid passage to the solenoid valve; and a rod-side relief valve configured to release the pressure in the bypass passage to a rod side chamber through the second fluid passage.
