摘要： The air damper includes a piston reciprocating within a cylindrical housing. The piston includes a lip seal which is made of rubber or thermoplastic elastomer impregnated with a minimum of 3% molybdenum/seal part weight, or a minimum of 2% polytetrafluoroethylene or silicone/seal part weight or a minimum of 1% wax/seal part weight. The lip seal is coated with a minimum of 0.5%/seal part weight graphite powder/molybdenum disulfide. The housing is made with a minimum of 2% silicone impregnated thermoplastic or a minimum of 2% moly sulfide impregnated thermoplastic. This provides for increased smoothness of operation of the air damper, particularly at low speeds.

摘要： The air damper includes a housing with cylindrical walls and a piston assembly reciprocating therein. The piston assembly includes an interior surface against which a seal abuts. The interior surface is textured in a grained pattern so that interstices are formed between the seal and the interior surface thereby forming an effective air passageway for damping. A cylindrical spacer spaces the interior surface from a retainer and the seal is engaged around the cylindrical spacer and between the retainer and the interior surface. An alternative embodiment inserts textile material through a damping orifice in order to vary the rate of damping.

摘要： A piston-cylinder unit includes a cylinder having an axis and an inner surface and a piston assembly attached to a piston rod and received in the cylinder for axial movement. The piston assembly includes a piston body, which has a plurality of radially resiliently deformable wall portions at its perimeter, the wall portions being spaced apart circumferentially from each other. Each wall portion has opposite ends that are joined integrally with the piston body and is defined by an opening in the body. Each wall portion engages the inner surface of the cylinder and deforms resiliently radially with respect to the axis of the cylinder to compensate for tolerance variations in the inner surface of the cylinder. The piston assembly may include a piston ring, which is received on the piston body with centering surfaces to restrict its radial movement and which functions to block and unblock a fluid bypass between sections of the cylinder on opposite sides of the piston assembly.

摘要： A positioning element to position two objects which are movable in relation to one another includes a cylinder in which there is an axially movable piston rod with a piston. The piston sealingly divides the cylinder into two working chambers by a piston ring, each of the working chambers containing blocking medium. The sealing by the piston ring can be bypassed during an insertion stroke of the piston rod. The piston includes a piston base body and a valve element, the valve element being movable along the base body to open and close a flow connection between the working chambers. An external opening force can displace the valve element to open the flow connection and permit an automatic extension stroke of the piston rod. The valve element remains open during the extension stroke on account of the flow of blocking medium through the flow connection. The valve element can be displaced to close the flow connection in response to stopping the extension stroke of the piston rod to position the two objects. To restart the extension stroke of the piston rod, a greater external opening force can be required than was necessary to start the initial extension stroke of the piston rod.
摘要翻译：用于定位可相对于彼此的两个物体的定位元件包括气缸，其中存在具有活塞的可轴向移动的活塞杆。活塞通过活塞环将缸体密封地分成两个工作室，每个工作室包含阻挡介质。在活塞杆的插入行程期间，活塞环的密封可以被旁路。活塞包括活塞基体和阀元件，阀元件可沿基体移动以打开和关闭工作室之间的流动连接。外部打开力可以移动阀元件以打开流动连接并允许活塞杆的自动延伸行程。考虑到通过流动连接的阻塞介质的流动，阀元件在延伸冲程期间保持打开。响应于停止活塞杆的延伸行程以定位两个物体，阀元件可以移位以关闭流动连接。为了重新启动活塞杆的延伸行程，可以需要比开始活塞杆的初始延伸行程所需的更大的外部开启力。

摘要： A piston for a shock absorber as may be used in an automobile comprises a piston body, and a piston ring which covers the outer periphery thereof. One end of the piston ring is formed as a bend, which is received in a first receiving groove formed in the piston body. The first receiving groove comprises opposing end faces which extend in a direction orthogonal to the axis of the piston body, and a bottom surface which connects together the both end faces. The tip of the bend is disposed in abutment against the corner defined by one of the end faces and the bottom surface. As compared with the prior arrangement in which the end face comprising the corner is formed as a tapered surface, the tip of the bend is less likely to be displaced radially outward, thus reducing the possibility that he bend may be disengaged from he first receiving groove.

摘要： A piston for use in a hydraulic cylinder which is subject to sudden and extremely high shock load pressures and high temperature operating conditions is provided with a plurality of interlocking axially-spaced circumferential grooves. A relatively thin, flat washer of heat-formable fluoropolymer is snapped over a retaining ring integral with the piston and the piston is then moved axially through a heated hot-forming cylinder, causing the washer to conform to the cylindrical shape of the piston. At least one circumferential groove has a side wall which is undercut relative to its cylindrical surface to provide a locking angle. Preheating the washer prior to hot-forming the band and forming a sloping ramp in opposition to the undercut side wall result in improved flow of the fluoropolymer toward the undercut side wall. An additional advantage of the preheating is the formation of an improved band skirt with an improved, sharply-defined sealing edge.

摘要： A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by flow restrictive passages formed in the piston or in the cylinder wall. When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through the restrictive passages resulting in heating of the fluid. When the strut rebounds or extends its piston rod fluid is forced to flow through the restrictive passages preferably at a more restricted rate. The flow passages are arranged to direct fluid flow toward the outer cylinder borewall to improve heat transfer to the exterior of the strut and minimize heating of the fluid contained in the cylinder chambers, and preferably in such a way as to minimize intermingling with a significant portion of the remaining fluid.

摘要： A vibration isolating and damping suspension strut for vehicle undercarriages comprising an elongated cylinder and piston structure wherein the cylinder is divided into opposed chambers which are in communication with each other by passages formed in the piston and in a flow restricting shuttle valve mounted on the piston rod. When the strut undergoes a retraction stroke of the piston to absorb loads silicone fluid is compressed in the opposed chambers and transferred from the chamber opposite the piston rod to the rod side chamber through passages in the piston only. When the strut rebounds or extends its piston rod fluid is forced to flow through passages in the shuttle valve member and the piston flow passages at a more restricted rate. The piston flow passages and the shuttle valve are arranged to direct fluid flow toward the outer cylinder borewall to improve heat transfer to the exterior of the strut and minimize heating of the fluid contained in the cylinder chambers. Alternate embodiments of the suspension strut have spiral fluid transfer grooves formed on the periphery of the piston or on a cylinder sleeve insert member.
