A door handle rate controller is disclosed. The door handle rate controller includes a damper assembly operatively connected to a door handle such that a movement of the door handle is dampened. The damper assembly may be a piston and cylinder type damper having a piston and a piston rod mounted within a body for reciprocal movement in the body along its longitudinal axis. The damper assembly extends longitudinally from a damper head to an end of the piston rod. A handle side mount and a mounting bracket may be provided to secure the damper assembly to a first and second portion of the door handle. The handle side mount has a first housing bracket pivotally coupled to the end of the piston rod, and a second housing bracket arranged to pivotally couple to the first portion of the door handle. The mounting bracket is defined by an first opening arranged to receive the damper head, and a second opening arranged to receive the second portion of the door handle. The mounting bracket is pivotally coupled to the damper head.

A damping device of a window covering is provided, including a headrail, a covering material, and a driving device, wherein the driving device is located in the headrail to raise and extend the covering material. The damping device is provided in the headrail, and includes a metal member and a magnetic member, wherein at least a magnetic pole of the magnetic member faces the metal member. The metal member is located within a magnetic field of the magnetic member. Either one or both the metal member and the magnetic member is drivable by the driving device to make the metal member and the magnetic member move relative to each other. Whereby, the damping device is able to provide a desired damping effect at different temperature or after a long period use, such that the rotation of the metal member and the movement of the covering material are slowed down.

A damping-force generation mechanism includes: a first flow path forming portion forming a flow path in which a fluid flows; a first valve configured to control a flow of the fluid in the flow path; a back pressure chamber forming portion forming a back pressure chamber configured to apply a back pressure to the first valve; a second flow path forming portion including a plurality of connection flow paths connected to the back pressure chamber; and a second valve provided to face the second flow path forming portion and configured to control flows of the fluid in the plurality of connection flow paths.

A rotary damper that does not cause a problem that a rotational resistance fluctuates during a rotation of a rotor is provided. On a bottom surface of a housing, a plurality of walls are erected concentrically centered on a bearing portion. Notches are formed in the walls at point-symmetrical peripheral positions centered on the bearing portion, and each notch is distributed and arranged at peripheral positions that evenly divide a circumference centered on the bearing portion between the adjacent walls. On a side surface of a rotor, a plurality of walls are erected concentrically centered on a center pin at a pitch deviated from a standing pitch of the walls of the housing by a half pitch. Notches are formed in the walls at point-symmetrical peripheral positions centered on the center pin, and each notch is distributed and arranged at peripheral positions that evenly divide a circumference.

Disclosed herein is a cooling device comprising a cooler body, wherein the cooler body has a first chamber and a second chamber, a cooler body cap disposed to fluidly couple the first chamber and the second chamber, wherein the cooler body cap has a recess that is suitable to receive a base valve, a first hose that is fluidly coupled to the first chamber, a second hose that is fluidly coupled to the second chamber, and an adapter, wherein the adapter is connected to the first hose and the second hose, wherein the adapter has channels to direct fluid flow.

Described herein is a bypass port piston comprising: a main damping piston, wherein the main damping piston has a plurality of standard ports, wherein the main damping piston has at least one bypass port, face shims disposed on at least one side of the main damping piston such that fluid flow through the plurality of standard ports is restricted, at least one check spring coupled to the main damping piston, at least one check shim disposed to cover the at least one bypass port and coupled to the at least one check spring, wherein the at least one check spring keeps the at least one check shim in an open position, and a position sensitive spring disposed to close the check shim as the main damping piston is pressed against the position sensitive spring.

A damping force generating mechanism includes: a flow passage formation part that forms a flow passage through which a liquid flows; a valve configured to control a flow of the liquid in the flow passage; a back pressure control valve configured to control a pressure in a back pressure chamber that provides a back pressure to the valve by inflow of the liquid; and an accommodation part that is in a tubular shape with one side opening end narrower than another side opening end, forms the back pressure chamber, and accommodates at least the valve and the back pressure control valve.

A vibration damper for vehicles includes a damper tube which is at least partially filled with damper medium and which has a longitudinal axis along which a piston rod is movable back and forth. A working piston is movable jointly with the piston rod, by means of which working piston the interior space of the damper tube is divided into a piston-rod-side working space and a piston-rod-remote working space. The vibration damper has a leakage indicator for the damper medium.

A damper for a telescopic fork leg for a front fork of a vehicle, wherein the damper comprises a twin-tube cylinder and a piston rod assembly comprising a piston rod, wherein a first piston is attached to the inner end portion of the piston rod, wherein a second piston is attached to the piston rod between the first piston and an outer end portion of the piston rod, wherein the inner tube is provided with at least one outlet hole 19 through the wall of the inner tube, the outlet hole being positioned such that a sealing portion of the second piston at compression of the damper travels past at the at least one outlet hole, and wherein the inner tube is provided with at least one return hole through the wall of the inner tube, the at least one return hole being positioned such that it connects a chamber of the twin-tube cylinder to an outer volume of the cylinder.

A damper assembly has a longitudinal axis and includes a damper housing with a side wall portion and an end wall portion defining a damping chamber containing a quantity of damping fluid. A photon source and a photon receptor are operatively disposed in optical communication with the non-gaseous damping fluid in the damping chamber. The photon source is operable to direct a photon through the non-gaseous damping fluid toward an associated target surface. The photon receptor is operable to receive the photon reflected off the associated target surface through the non-gaseous damping fluid. A sensor suitable for such use as well as spring and damper assemblies and suspension systems are also included.
