20110056785 | Vibration Damper - A vibration damper including a cylinder with a cylinder-side connection member. The at least one mounted component is fastened to the cylinder by a material bond. The cylinder and the mounted component are made of plastic. The mounted component and/or the cylinder are based on at least one ready-prepared semi-finished product that forms the surface of the vibration damper on at least one body side in the final state. Plastic supplemental volume fractions determine the finished body contour. | 03-10-2011 |
20110162928 | Super-Compressible Piston Shock Absorber - Piston-in-cylinder type shock absorbers are disclosed that are compressible to less than half of their extended length, thereby eliminating the current need for automotive suspensions to accommodate unwieldy shock absorbers that, even when fully compressed, must be longer than the amount of permitted axial suspension travel at the shock absorber's connection point. Since the disclosed shock absorbers are super-compressible, they are also super-extendable, which is extendable beyond double their compressed length. In some embodiments, this super-compressibility and super-extendibility are rendered possible by the use of a rigidly interleaved, oppositely-oriented, axially-balanced, free-floating bank of gas-charged cylinders. | 07-07-2011 |

The composite base assembly defines a chamber for at least partially accommodating the inner assembly that terminates at a floor. The composite base assembly has a lower element disposed adjacent to the floor for at least partially engaging the second end of the pressure tube. The lower element defines at least one gap for facilitating fluid communication between the pressure tube and the chamber. | 05-26-2016 |

20080236969 | HYDRAULIC CYLINDER LIMITER - A limiter bracket, for restricting the stroke of a hydraulic cylinder, is formed from a U-shaped member having a central base portion and two opposing sidewall. The base has a semi-circular retention slot extending from an off center position centrally located detent within the base. The opening of the slot is asymmetrically located at an off center position along an edge of the base so that the rod of a cylinder is both horizontally and vertically displaced during positioning within the limiter. Once the rod is located in the detent of the limiter, a pivot pin is inserted through a connector at the end of the rod and the aligned attachment holes in the sidewalls securing the limiter to the rod. The end of the cylinder body will contact the base of the limiter during retraction of the rod thus limiting the overall stroke of the cylinder. | 10-02-2008 |

20100193310 | YAW DAMPER WITH PUMP - Yaw damper for damping yaw motions between two vehicle parts. This includes in the customary manner a piston part and a cylinder part, wherein that piston part is provided with a piston which divides that cylinder part into two chambers. Between these two chambers, connecting lines are present. The embodiment of these connecting lines determines the damping characteristic which governs the motion between the piston and the cylinder part. Especially for vehicle parts which move at higher speeds and/or high frequencies, such as train sets, it is desirable to provide a damper which is as stiff as possible. For this purpose, the present invention proposes the installation of pumping elements which, as far as possible, increase the pressure in the chambers which are formed by the piston in the cylinder part. Preferably, this construction is realized such that this pressure automatically decreases at lower speeds and/or low frequencies. | 08-05-2010 |
20120325605 | BICYCLE WITH SUSPENSION - A bicycle can include a suspension system with a shock absorber. The shock absorber can have a sag position which can be adjustable. Sag refers to the amount of movement experienced by the suspension under a static load, such as that of the weight of a rider. Methods and systems to set sag can include at least one valve in fluid communication with a gas chamber of the shock absorber. In some embodiments, the at least one valve can be used to automatically set the sag position based on an individual's weight and riding position. | 12-27-2012 |
