... 136,813. Agnelli, C. Dec. 14, 1918, [Convention date]. No Patent granted (Sealing fee not paid). Dash-pots and fluid-friction vibration dampers.-In a liquid shock-absorber for vehicles, the cylinder and piston are connected respectively to the two parts whose displacements are to be damped, such as an axle and the frame, and the piston is formed with passages, some which are traversed by the liquid when the piston is forced in one direction by the shock and the others during the reverse movement due to the reaction of the springs. The portion of the cylinder wall in which the piston is normally situated is provided with grooves 6 so as to prevent any damping action for small shocks. The piston 2 is mounted loosely on the rod 3, but is prevented from rotating by engaging slots 7 in the cylinder wall. Disks 8, 9 are fixed to the rod 3 so that, by rotating the piston-rod, the mouths of the passages in the piston can all be varied together. The passages for the forward flow are made of larger ...

ENERGY ABSORPTION APPARATUS

... 1382131 Dampers using compressible solids MENASCO MFG CO 26 June 1972 [19 July 1971] 29807/72 Heading F2S A piston-cylinder shock absorber for mounting a bumper on a vehicle (not shown) utilizes the flow of a compressible solid around the piston 44 from one side to the other, the size of the flow path increasing throughout the stroke of the piston. This provides a constant damping force (Fig. 10, not shown). The flow path is provided by grooves (not shown) in the cylinder wall or a series of slots 64 in a cylinder liner 46. The arrangement of slots is such that as the stroke of the piston increases greater slot area becomes available to effect transfer of the compressible solid from one side of the piston to the other. A preferred solid is specified. The compressible solid provides a return force.

CONSTRUCTION ASSEMBLY

A CONSTRUCTION ASSEMBLY A flap member, e. g. a trunk lid of a motor vehicle, is pivotal mounted on a framework, e. g. a motorcar framework. The flap member is assisted in its upward movement by a gas spring. The thrust of the gas spring biases the flap member towards an upper position. In this upper position further upward movement of the flap member is locked by a relief pressure valve between the working chambers of the gas spring. By applying external force to the flap member assisting the thrust of the gas spring, the flap member may be moved beyond said upper position while opening said relief pressure valve. If the external upward directed force ceases the relief pressure valve closes again and the flap member is maintained in the new position by the thrust of the gas spring and the locking action of the relief pressure valve.

Shock absorber

FIELD: vehicles. SUBSTANCE: invention relates to devices for damping vibrations of vehicle suspensions. The shock absorber contains a cylinder with radial holes and a rod with a piston. The compensation chamber is located in the lower part of the cylinder. In the middle part of the cylinder, a clip is installed. The throttle and the safety valves of the compression and rebound motion are installed in the piston. Two hydraulic channels and two check valves, made coaxially in the tee-fitting, are installed outside the cylinder. The upper and lower bolts are mounted laterally at the upper and lower ends of the cylinder and are connected to the over- and under-piston cavities through the upper and lower radial holes. Inside the clip, a groove is made, communicating with radial holes in the middle part of the cylinder. The groove is also connected to the upper and lower bolts. A sealing ring is installed in the middle part of the piston. The upper and lower edges of the piston are made in the form of truncated cones, forming the upper and lower annular conical slots with the cylinder. EFFECT: technical result is simplifying the design and reducing the weight of the shock absorber while increasing its damping properties, reliability and smooth motion of vehicles on almost any type of road. 1 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 750 314 C1 (51) МПК F16F 9/48 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК F16F 9/48 (2021.02) (21)(22) Заявка: 2020141113, 14.12.2020 (24) Дата начала отсчета срока действия патента: Дата регистрации: 25.06.2021 (45) Опубликовано: 25.06.2021 Бюл. № 18 2 7 5 0 3 1 4 R U (54) Амортизатор (57) Реферат: Изобретение относится к устройствам для гашения колебаний подвесок транспортных средств.
