20100048334 | HYDRAULIC TENSIONING UNIT FOR FLEXIBLE DRIVES - A hydraulic tensioner intended for use in chain drives of internal combustion engines. The hydraulic tensioner has a pot-shaped housing in which a piston is elastically suspended against a traction element and guided for longitudinal displacement. A damping device forms a leak gap which serves to damp adjusting movements of the piston. The leak gap is defined by a bushing which is inserted into the housing and, at the same time, guides the piston. During an adjusting movement of the piston towards a pressure chamber filled with a hydraulic fluid, a fractional quantity of the hydraulic fluid is displaced via the leak gap. An adjusting movement of the piston in the opposite direction causes a re-flow of the hydraulic fluid via a one-way valve arranged in the housing. | 02-25-2010 |
20100292036 | TENSIONING DEVICE FOR THE TRACTION MECHANISM DRIVE IN A TIMING SYSTEM ON A MOTOR VEHICLE - A tensioning device for the endless drive in a timing system on a motor vehicle, which has a tensioning piston that can move along a path axis in a housing, within which a pressure chamber is located which houses a working medium which brings about a movement of the tensioning piston in the housing and has a valve seat, connected to the exterior of the tensioning piston by an outlet and accommodating a valve body essentially matching the shape of the valve seat. The valve body is tapered along the axial path axis to the outlet, which allows for a large chamber between the valve body and the valve seat. The path that the working medium, on bleeding gas bubbles from the same, takes from the pressure chamber to the outlet is longer, which increases the hydraulic resistance and restricts and limits emptying of working medium from the tensioning piston. | 11-18-2010 |
