摘要： A variable-damping-force shock absorber such that the damping force determined through an orifice selected by an orifice adjuster according to the driver's preference can further automatically be increased during extension for improvement in road-holding ability and decreased during compression for improvement in riding comfort. The shock absorber according to the present invention comprises an annular member formed with an orifice and a disk valve disposed on top of the annular member. During extension, the disk valve is closed for allowing fluid to by-pass through an orifice of the annular member; during compression, the disk valve is opened for additionally allowing fluid to by-pass through the annular member. Further, since the various elements for adjusting the damping force are completely housed within the piston rod, it is possible to increase the stroke of the piston rod.

摘要： A variable-damping-force shock absorber in which the motor for rotating the orifice adjuster is housed within the cylinder and the orifice-adjuster position sensor for outputting binary coded sensor signals is incorporated. Therefore, it is possible to reduce noise generated from the motor while improving the lifetime of the motor because mud or rain water will not adhere onto the motor and to improve the precision and the response speed in rotating the orifice adjuster because the adjuster can be feedback controlled in digital fashion. Further, since the driven shaft of the motor or the reduction gear is loosely coupled with the orifice adjuster in the axial direction thereof, it is possible to reduce the torque or the size of the motor, because fluid pressure is not directly applied to the driven shaft via the orifice adjuster.

摘要： An oil seal or fluid seal for providing a seal between a cylinder and a piston rod is provided. The oil seal has an annular seal lip which has on a conical inner circumferential surface thereof a plurality of annular projections which are arranged axially of the seal lip. One of the annular projections which is located more axially outside of the cylinder is larger in the height above the inner circumferential surface than one of the annular projections which is located more axially inside of the cylinder. By this, under a condition where the annular projections which are located more axially inside of the cylinder are subjected to a high pressure within the cylinder, the annular projections which are located more axially inside of the cylinder and the annular projections which are located more axially outside of the cylinder are nearly equal in the contact pressure against the piston rod, thus causing all of the annular projections to deform nearly equally. The annular projections are all brought into contact with the piston rod at nearly equal contact areas.

摘要： A hydraulic shock absorber is provided which includes generally a cylinder assembly to define working and reservoir chambers therewithin, a piston rod, a rod guide member which guides bounding and rebounding strokes of the piston rod, and an oil seal contacting with the piston rod to seal an opening of the cylinder assembly. The rod guide member includes outer and inner supporting sections. The inner supporting section also includes outer and inner wall sections which are coaxially arranged with a preselected interval therebetween. The outer wall section is spaced from an inner wall of the cylinder assembly to provide flexibility to the rod guide in cooperation with the inner wall section. The shock absorber further includes a reinforcement partly inserted into the oil seal to provide flexural rigidity to the outer supporting section of the rod guide and a communication path defined by a chambered surface formed on a peripheral surface of the reinforcement and a recessed portion formed in an edge portion of the first supporting section to fluidly connect the working and reservoir chambers.

摘要： A piston ring of Teflon (trademark of E.I du Pont de Nemours & Co, Ltd.), i.e., polytetrafluorethylene fiber, is mounted on a piston. The piston ring has an integral portion in the form of a series of axially spaced circumferential projections received in the respective circumferential spaced grooves of the piston. The piston is projected radially and outwardly to abut an axial end of a sleeve portion of the piston ring to limit axial movement of the piston ring.

摘要： A hydraulic damper with a rod guide made by pressing a circular plate is disclosed. This rod guide includes an inner tubular portion defining a bore supporting a piston rod, an outer tubular portion extending in the same direction as the inner tubular portion does, and a flange portion extending radially outwardly from the outer tubular portion. A ring is connected between an inwardly turned axial end portion of an outer tube and the flange portion. An annular sealing element retainer is disposed in the ring. The ring provides a transmission path of a force, thus preventing the sealing element retainer from being subject to the force.
