摘要： An inertia-actuated valve assembly includes a valve housing, a valve body and a biasing element. The valve housing includes a groove that has an open end fluidically accessible from along one side thereof. The valve housing includes a flow channel extending therethrough in fluid communication with the groove from along an opposing side of the valve housing. The valve body is positioned within the groove of the valve housing such that the valve body and the valve housing are axially co-extensive along at least a portion thereof. The biasing element operatively engages the valve body and generates a biasing force urging the valve body in a first axial direction. The biasing force is greater than a predetermined dynamic gas pressure threshold value multiplied by a pressure area and is less than or approximately equal to a valve body mass multiplied by 2.5 times the nominal acceleration due to gravity.

摘要： A damper valve includes a controlled flow channel between inlet and outlet sides; a controlled valve in the controlled flow channel; a movable valve body acting on the controlled valve to change a closing force of the controlled valve; and a control chamber. The control chamber includes a control chamber inlet in fluid connection with the valve inlet side upstream of the controlled valve; a configuration providing a variable volume of the control chamber, a change in volume of the control chamber moving the movable valve body; and a first flexible wall allowing movement of the movable valve body. The first flexible wall provides an effective surface area against which the fluid pressure in the control chamber acts, the effective surface area decreasing upon movement of the movable valve body outward of the control chamber, the first flexible wall including a flex plate bearing against a curved surface.

摘要： A movement stage for a hydraulic shock absorber has a damping volume and a stage throttle with a valve disk, an analogue piston, and an elastic biasing means supported on the analogue piston and on the valve disk. The valve disk has a pressure surface defining a portion of the surface of a disk valve arranged upstream of an entry edge of a disk valve seat. The analogue piston has a pressure surface facing away from the biasing means. The valve disk pressure surface and the analogue piston pressure surface are impinged by damping fluid flowing out of the damping volume as the shock absorber moves in a movement direction. The analogue piston pressure surface is larger than the valve disk pressure surface when projected in the closing direction of the disk valve so that the analogue piston is displaced and the bias of the valve disk increases.

摘要： A seal assembly for sealing a shaft bearing includes a seal housing, first and second seal rings retained by the seal housing, an annular chamber formed between the first and second seal rings and a connecting channel configured to place the annular chamber in fluid communication with a bearing-housing-side oil space. When the seal assembly is installed on a shaft, the connecting channel is configured to permit a fill-level equalization between the oil space and the annular chamber when the oil space is filled to a first possible fill level (N1) and to prevent the fill-level equalization between oil space and annular chamber when the oil space is filled to a second possible fill level (N2).

摘要： A shock absorber includes a first end and a second end that reciprocate relative to one another. The shock absorber includes a gas spring chamber, a damping chamber, and a floating piston. The first side of the floating piston is in fluid communication with the gas spring chamber. The second side of the floating piston is in fluid communication with the damping chamber. The gas in the gas spring chamber applies pressure against the floating piston, which applies pressure to the substantially incompressible fluid in the damping chamber. This pressure transfer may be adequate to minimize or prevent cavitation.

摘要： Support and carrier assemblies are dimensioned for securement along a damper housing and dimensioned to operatively support an end member of a gas spring assembly on the damper housing as well as to form a substantially fluid-tight connected between the end member and the damper housing. The support and seal assembly can include a seal assembly with a seal carrier and at least one sealing element. The seal carrier can be dimensioned for securement along the damper housing. The at least one sealing element can be dimensioned sealingly engage the seal carrier and one of the end member and the damper housing to at least partially form the substantially fluid-tight connection therebetween. End member assemblies including such support and carrier assemblies are included. Gas spring and damper assemblies as well as suspension systems are also included.

摘要： A frequency-tunable vibration damper includes a first container having rigid wall regions and compliant wall regions. A second container is coupled to the first container such that a wall region of the second container includes one of the compliant wall regions. A liquid fills the first container and a gas fills the second container. A flow restrictor is included in the second container and is spaced-apart from the one of the compliant wall regions included with the second container.

摘要： A front fork includes a fork main body, a damper cartridge, and a closing member. The damper cartridge includes a cylinder, a piston mounted on a piston rod, and a rod guide which guides the piston rod and to which a fluid filling port that allows the outside of the cylinder to communicate with the fluid chamber is provided. The closing member is provided on the rod guide and closes the fluid filling port.

摘要： An arrangement for mounting a suspension spring of a spring strut for a motor vehicle may include a spring plate that is arranged on a damper tube of a vibration damper of the spring strut such that an end side of the suspension spring is supported on the spring plate. A protective element for protecting a piston rod of the vibration damper may also be attached to the spring plate. The spring plate may include features that help minimize or even eliminate contact between the protective element and the damper tube. For example, the spring plate may include tongues that extend from a ring-shaped main structure of the spring plate, wherein inner sides of the tongues may lie against the damper tube and outer sides of the tongues may guide the protective element.
