摘要： A monitoring system for a dual-stage, separated gas/fluid shock strut may comprise a controller and a tangible, non-transitory memory configured to communicate with the controller. The tangible, non-transitory memory may have instructions stored thereon that, in response to execution by the controller, cause the controller to perform various operations. Said operations may include determining, by the controller, a shock strut stroke at which a secondary chamber of the shock strut is activated, calculating, by the controller, a volume of oil in an oil chamber of the shock strut, calculating, by the controller, a volume of gas in a primary chamber of the shock strut, and calculating, by the controller, a volume of oil leaked into the primary chamber of the shock strut.

摘要： A suspension damper includes a housing bounding a main chamber. A piston rod is slideably disposed within the main chamber of the housing. A main piston is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.

摘要： A suspension system, particularly for a pedal-driven vehicle, comprising a telescoping strut having first and second telescopingly and coaxially engaged members, and having a damping system comprising a damping fluid, a damping piston connected to a piston rod, an inertia-activated compression fluid flow control mechanism and a pressure-activated compression fluid flow control mechanism disposed in the first telescoping strut. The inertia-activated compression fluid flow control mechanism comprises a valve body biased by a valve spring into a first position over a radial groove formed on the piston so that the valve body prevents fluid flow through an inertia-activated compression fluid flow circuit in response to force inputs imparted to the vehicle frame. The valve spring and valve body are connected to the piston rod which extends into the first telescoping member and is attached to the vehicle wheel, such that the valve body may be moved into a second position permitting fluid flow through the inertia-activated compression fluid flow circuit by force inputs imparted to the vehicle wheel. Because the inertia-activated fluid flow control mechanism is inertia-activated and not pressure-activated, a force impact imparted to the vehicle wheel results an fluid flow through both the pressure-activated and inertia-activated flow circuits, whereas force inputs such as from pedalling, weight shifting and acceleration or deceleration forces do not result in flow through the inertia-activated circuit. The suspension system therefore resists the absorption of pedal drive energy, provides a ride-leveling effect, and provides a broad range over which the damping system may be adjusted.

摘要： An oleopneumatic shock absorbing device including a hydraulic fluid-filled cylinder (1) combined with a movable assembly moved by outside forces for circulating the hydraulic fluid. The movable assembly consists of a hollow mobile piston (3) on the end of a push rod (2) with an internal longitudinal space (13) forming a reservoir for the hydraulic fluid. When the piston (3) and the push rod (2) are moved, the fluid flows through a variable flow-rate transfer channel (11) providing variable, e.g. gradual shock absorption throughout both the outward stroke and the return stroke.
