Abstract: A hydraulic shock absorber for use in a bicycle front fork include a retractable tube set containing hydraulic fluid, a locking mechanism mounted inside the retractable tube set, and an adjustment mechanism mounted on a top side of the retractable tube set and controllable to lock out and open a hydraulic fluid passage in the locking mechanism for transient pressure relief, assuring riding comfort.

Abstract: A hydraulic front fork includes a fixed locking mechanism mounted in the upper fork tube, and a first adjustment mechanism mounted in the top end of the upper fork tube adjustable to control the flowing path of the hydraulic fluid through the locking mechanism such that the bicycle is suitable for running on slopes and smooth road surfaces efficiently when the hydraulic fluid is locked out and prohibited from passing through the locking mechanism, and the hydraulic front fork can absorb shocks when the hydraulic fluid is allowed to pass through the locking mechanism.

Abstract: A front fork of a bicycle, which has damping function, has a lower fork having a closed bottom. An upper fork tube is inserted into the lower fork for reciprocation relative to the lower fork, which has a nozzle at a top thereof. Oil is received in a space between the lower fork and the upper fork tube. An air chamber is formed in a space between a surface of the oil and the nozzle, which a gas is issued therein and a pressure of the gas is greater than an atmospheric pressure, and a damping device, which is mounted at a bottom of the upper fork tube and under the surface of the oil, has multiple, variable oil flow paths through which oil passes as the upper and lower fork member reciprocate to provide various damping characteristics dependent on the relative speed or impact the fork members experience with respect to each other.

Abstract: A hydraulic type shock-absorbing front fork used in a bicycle includes a locking mechanism fixedly mounted in the upper fork tube of the front fork, a main adjustment unit mounted in the top end of the upper fork tube of the front fork and adjustable to allow or not allow the hydraulic fluid to pass through the locking mechanism, and a fine adjustment unit mounted in the top end of the upper fork of the front for regulating the range of transient release of pressure during the lockout mode of the front fork to provide a comfortable riding to the user.

Abstract: A front fork for a vehicle includes an upper front fork tube, a lower front fork tube movably coupled to the upper front fork tube, a fluid contained in the upper and lower front fork tubes, and a damper fixedly sealedly mounted inside the upper front fork tube. The damper has a fluid inlet, a fluid outlet, a through hole in communication with the fluid inlet, and a blocking member movably mounted in the fluid inlet for regulating upward flowing rate of the fluid from the lower front fork tube into the upper front fork tube through the fluid inlet and the through hole upon movement of the upper front fork tube relative to the lower front fork tube.

Abstract: Disclosed is a front fork damper installed in a bicycle front fork formed of a fork pipe, a bottom case coupled and axially movable relative to the bottom case, and a hydraulic fluid filled in between the bottom case and the fork pipe. The front fork damper is joined to the bottom end of the fork pipe to buffer movement of the bottom case relative to the fork pipe in such a manner that the hydraulic fluid passes upwards through the front fork damper rapidly at a high flow rate, and passes downwards through the front fork damper slowly at a low flow rate.

Abstract: A front fork shock-absorbing damper for use in between an upper front fork tube and a lower front fork tube of a vehicle's front fork for producing a damping effect upon movement of the upper front fork tube relative to the lower front fork tube includes a control rod movable by an external force between a top locking position where the front fork shock-absorbing damper does no work, and a bottom unlocking position where the front fork shock-absorbing damper is functioning.
