摘要： A valve mechanism includes: a cylindrical body; a plurality of valve bodies; and a drive valve. The drive valve includes a shaft portion having a flow path penetrating in the axial direction, and a first step portion extending from an outer peripheral surface of the shaft portion to a radial outside of the shaft portion. The shaft portion has a protrusion portion protruding further toward the cylindrical body side than the first step portion and a base portion extending to a side opposite to the protrusion portion with respect to the first step portion. A gap between the valve bodies is changed by elastically deforming an inner peripheral portion of the valve body, which comes into contact with the drive valve moved in a direction approaching the valve body, in a direction approaching the cylindrical body with respect to an outer peripheral portion of the valve body.

摘要： The construction of the shock absorber disclosed in DE-A-2945015 is independently adjustable in two directions however, the adjustment only leads to a variation in the pre-spring tensions in a fixed combination of valves. Only the magnitude of the damping forces may be adjusted, however not the characteristic. The construction of the shock absorber according to the present invention provides the possibility to adjust the characteristic.

摘要： A variable damping shock absorber is disclosed. The shock absorber has a two-wire electrical lead extending into the piston rod. The electrical energy provided by the lead drives a drive motor, which rotates in alternating directions depending on the setting of an internal switch that switches upon occurrence of voltage spike, which occurs when the motor has driven an internal rotatable valve as far as the valve can go within the confines of rotation permitted by the valving. The drive motor then drives an internal valve between an open and closed position, which in turn opens and increases, or closes or reduces, a path in fluid flow from one cavity to another as the piston moves within the shock absorber.

摘要： A motor vehicle suspension system has a damper with a member rotatable through positions producing separate discrete damping characteristics. Feedback apparatus comprises a contact pad for each position, a brush rotating with the rotatable member, and an electric circuit generating an output voltage in a first voltage range when the brush does not contact a contact pad and in a second range when it does. The output voltage is repeatedly sampled to control a position count. An overrun detector responds to a predetermined change of the sampled output voltage from the second range to the first voltage range after deactivation of the motor at a selected contact pad to restart the motor so as to resume rotation of the rotatable member toward the selected contact pad.

摘要： A suspension control system for automotive vehicles automatically adjusts the damping strength of variable shock absorbers or other dampers in accordance with road surface conditions as recognized by frequency analysis of a vehicle height or vibration sensor signal. The sensor signal reflects vertical displacement of the vehicle body from the road surface and includes high-frequency components due solely to displacement of the wheels of unsprung mass relative to the road surface and low-frequency components due to displacement of the vehicle body or sprung mass. The sensor signal is filtered into these separate frequency bands, the amplitude of each of which is compared to a corresponding reference level. The results of comparison give an indication of the degree and scale of irregularities in the road surface; specifically, a high-amplitude low-frequency component indicates larger-scale bumps and dips capable of bouncing the vehicle whereas a strong high-frequency component reflects a rough-textured road surface, such as a gravel. The comparison information is sent to a suspension system controller which causes actuation of the shock abosrbers to a stiffer mode of operation when the low-frequency sensor signal components are relatively strong.

摘要： A spring fork, in particular for bicycles, with a suspension system and a hydraulic damping system, wherein a compression stage damping system (6) is provided for a spring deflection process and a traction stage damping system (5) is provided for a rebound process. At least one piston (3, 16, 27) is provided, which is located in the cylinder (2), and at least one connecting passage (17, 17a) is provided which connects the cylinder chambers located on both sides of the piston and is intended for the overflow of hydraulic medium (21). The compression stage damping system (6) which is activated during the spring deflection process can be blocked by closing the connecting passage (lockout). At least with the compression stage damping system (6) blocked, if appropriate also with the traction stage damping system (5) also blocked, a bypass passage (11, 20, 20a) which has a reduced cross-section in comparison to the connecting passage (17, 17a) is opened. As a result, the strong damping effect is largely maintained, in particular during the rocking peddling action, but on the other hand, automatic return of the fork to its initial position (sag position) is made possible.

摘要： A hydraulic dashpot with a cylinder (1), a piston (4), and a bypass. The cylinder is charged with fluid. The piston partitions the cylinder into two compartments (7& 8), travels back and forth therein on the end of a piston rod (2), and is provided with breaches and valves. The open cross-section of the bypass can be expanded and contracted and fixed in accordance with the direction the piston is traveling in, depending on whether the dashpot is in the compression or in the suction phase. The bypass is provided with an axially displaceable control component. One end of the control component comes to rest against a valve, its displacement being limited by stops. The bypass is accommodated in an axial bore through the piston rod. The bypass operates in conjunction with various outlets that open into the compartments. The control component is provided with at least one lateral flange and travels back and forth in at least one tube. The object is a smooth performance curve and low wear. The control component is accordingly in several parts, comprising at least two bypass control caps that axially travel up to stationary stops. The caps, in conjunction with axially variable components (18 & 21) that dictate the size of the open cross-section in both the compression and the suction phase, create a port.
