Abstract: A piston having a piston rod connected thereto is slidably fitted in a cylinder in which a hydraulic fluid is sealably contained. Extension-stroke and compression-stroke pilot type damping force control mechanisms are provided in the piston. A pilot control valve of the extension-stroke pilot type damping force control mechanism is formed by a pressure control valve having a valve seat, a valve body and a pressure-receiving portion. A pilot control valve of the compression-stroke pilot type damping force control mechanism is formed by a flow rate control valve having a spool. A slider having the valve body of the pressure control valve and the spool of the flow rate control valve is operated by a proportional solenoid, to thereby control a damping force for an extension stroke and a damping force for a compression stroke.

Abstract: A piston or plunger and a method for making the same A piston or plunger comprises a piston body and a sealing member. The piston body is preferably made from metal by moulding, such as casting or pressure moulding and sintering. The sealing member is made from a thermoplast, such as polytetrafluoroethylene (PTFE). The piston body has an outer or an inner peripheral surface part in which axially extending depressions or grooves are formed during moulding of the piston body. The axially extending grooves may be open at one or at opposite ends. An annular sealing member blank is applied to the peripheral surface part and is deformed and forced into tight engagement with the peripheral surface part and into the grooves or depressions formed therein. The sealing member formed is also exposed to a heat treatment. The piston or plunger having the sealing member applied to an outer peripheral surface part may, for example, be used in shock absorbers. Alternatively, the sealing member may be applied to an inner peripheral surface part. In such case the piston or plunger may be used as a stationary sealing device for encircling and sealingly guiding a reciprocating shaft or a piston rod.

Abstract: The invention relates to a system having an air spring flexible member (6) which is clamped between a cover plate (4) and a rolloff piston (10). The movement of the rolloff piston (10) is pregiven by a curved path (16). The rolloff piston (10) is curved with the curvature being at least segmentwise of the same orientation as the curvature of the curved path (16). Because of the curvature of the rolloff piston (10), a lateral offset of the flexible member (6) to the cover plate (4) can be substantially avoided when the rolloff piston (10) plunges into the flexible member (6). The formation of a rolling lobe (20) having a different width over its periphery is also avoided.

Abstract: A vibration damper has a cylinder tube which is divided into two work chambers by a piston, which is fastened to a piston rod. The piston has a piston body which has fluid passage channels which are covered by valve discs on supporting bodies with valve support surfaces, and the piston body is in a sliding or frictional connection, by way of at least one piston ring, with the cylinder tube. The piston ring covers the peripheral surface of the piston body and is axially supported respectively on the upper side and the lower side of the piston. The piston body is in a disc-shape, is in one piece and is manufactured by stamping. Starting from the piston base body, the piston body areas which are raised on one side of the piston are depressions on the axially opposite side of the piston. The piston ring is able to move axially as a function of the direction of movement, and is actuated by the friction force between the cylinder tube and the piston ring. Between the surface of the piston ring facing the piston and the surface of the piston, there is at least one advance opening cross section which is opened as a function of the axial position of the piston ring in relation to the piston body.

Abstract: Shock absorber valve for a hydraulic telescoping strut shock absorber, in which, running through a valve body, there are passages whose respective outlet-side openings are covered by ring-shaped valve discs, whereby the valve discs and the valve body are fastened and axially braced in line. The object of the invention is to make possible fully-automated assembly with short cycle times using the dry process, whereby a valve closing force independent of tolerances is achieved by using a method which generates as few chips from cutting and machining as possible. To achieve this object, the invention teaches that the valve discs and the valve body are threaded and prestressed onto a cylindrical component, whereby a fastening element is fixed to the cylindrical component.
