摘要： A vortex flow shock absorber includes a piston having a vortex chamber therein. The piston communicates with one fluid chamber defined in a absorber cylinder via a vortex chamber and with the other fluid chamber separated from the former by the piston via a flow restricting opening. One-way valve is provided in a piston rod which defines a fluid passage permitting one way flow of the fluid from the vortex chamber to one of the fluid chamber. The one-way valve is responsive to an excessive fluid pressure in the vortex chamber to relieve the fluid pressure exceeding a predetermined value. The piston and piston rod are attached together with pressure welding. This simplifies the assembling operation of the piston onto the piston rod.

摘要： A shock absorber with improved shock absorbing characteristiscs has a piston in which a vortex chamber is formed. The vortex chamber communicates with upper and lower fluid chambers via communication passages. One of the communication passage opens to the vortex chamber tangentially to produce a vortex in the vortex chamber. Within the vortex chamber, a member is normally elastically urged to narrow the area through which the fluid flows. The member is responsive to the fluid pressure exceeding a predetermined value to move against the resilient force in the direction increasing the area allowing fluid flow. A bottom fitting of similar construction and function is also disclosed.

摘要： A damping valve for a vibration damper includes a valve body, which has at least one flow channel with an inlet and outlet, through which a working medium flows from one side to the other side of the valve body, where the inlet and/or the outlet has a cross section which is larger than that of the flow channel. The inlet and/or the outlet has a flow deflection profile, in which a vortex flow is produced, the flow filaments of which form a fluid cushion for the working medium.

摘要： In the illustrative embodiments of the invention disclosed, the piston unit of a gas spring incorporates a meander-shaped fluid passage for interconnecting the working chambers on either side of the piston unit so as to dampen movement of the piston rod relative to the cylinder. The meander-shaped passages may be constituted by a sequence of passage sections arranged at right angles to one another and, in one embodiment, are formed in the end faces of the piston member so as to lie in planes transverse to the axis of the cylinder. If desired, additional fluid passage units may be connected in series to provide an enhanced damping effect.
