摘要： The damper assembly includes a tubular member, a rod, a primary piston, a secondary piston, and a resilient member. The tubular member includes a sidewall and a cap positioned at an end of the sidewall. The sidewall and the cap define an inner volume. The sidewall includes a shoulder separating the tubular member into a first portion and a second portion. The resilient member is disposed between the secondary piston and the cap and thereby is positioned to bias the secondary piston into engagement with the shoulder.

摘要： The present invention addresses the problem of stabilizing the state of assembly of a seal member while allowing movement of a piston member in a direction that reduces one space inside a cylinder member with little resistance. The seal member includes a base portion located towards the one space, which is a first space inside the cylinder member, and an extending portion extending from the base portion toward the other space, which is the second space inside the cylinder member. The piston member is provided with a first holding portion that faces the base portion of the sealing member, a second holding portion that faces an extended edge of the extended portion of the sealing member, and a third holding portion that faces a held part formed on the inside of the extended portion of the seal member. A fluid passage is formed in the second holding portion.

摘要： Disclosed are a compound impact-resistant device and an application thereof. The compound impact-resistant device includes an inner cylinder, a first pressure sensor and an outer cylinder; an inner cavity of the inner cylinder is connected to a magnetorheological damper, a spiral valve element, a floating piston and a spring from bottom to top; and the outer cylinder is connected to a piston rod, a bottom end of the piston rod penetrates a top of the inner cylinder, the spring and the floating piston to be connected to the spiral valve element, and a portion below the spiral valve element is filled with hydraulic oil. The compound impact-resistant device can provide specific initial support force and achieve active self-adaptation to dynamic impact, thus solving the problems that traditional hydraulic buffers cannot provide initial support force and traditional mechanical crushing members have difficulty in providing large support force.

摘要： Shock absorber comprising a tubular base, a piston, a stem connected to the piston, and a plurality of fluid paths for connecting a working chamber and an accumulation chamber on opposite sides of the piston, one of which provides for a ring-shaped obstructing member arranged about the piston and able to slide along an axial length of the piston. The obstructing member comprises a bush of plastic material, which has a flexible lip portion extending from a rear end of the bush and having a radially outer surface tapered towards the rear end of the bush, the lip portion being adapted to seal against a radially inner surface of the base when the obstructing member is in a closed configuration. A support ring member is adapted to radially engage the lip portion of the bush from within, and to push it against the radially inner surface of the base.

摘要： A piston and cylinder type damper is provided, with a cylinder (11) having a piston assembly (15) mounted for reciprocal movement therein. The piston assembly (15) divides the cylinder (11) into two separate chambers (12a, 12b), with a restricted flow path (30, 31) for passage therebetween of damping fluid contained within the cylinder. A piston rod (13) is mounted for reciprocal movement with respect to the cylinder (11) and acts via a first one of the chambers (12a) on the piston assembly (15) in a first direction. A seal assembly (17) is provided for sealing between the piston rod (13) and the cylinder (11) in order to retain damping fluid in the first chamber (12a). The seal assembly (17) is movable axially with respect to the cylinder (11), with the cylinder further including a centering device (24) for assisting alignment of the seal assembly (17).

摘要： Disclosed is a hydraulic damper wherein the main damper tube has a narrowed section and it includes at least one additional piston assembly adapted to be received in the narrowed section to generate additional damping force. The piston assembly comprises a compression valve assembly and a rebound valve assembly each comprising at least one deflective disc. A sealing ring assembly is disposed between the compression and rebound valve assembles and comprises a first annular member having a plurality of channels covered by the deflective disc of the compression valve assembly; a second annular member having a plurality of channels, covered by the deflective disc of the rebound valve assembly; an axial projection between the annular members radially internal to the axial channels; and a sealing ring displaceable axially between the annular members and radially over the axial projection and adapted to cooperate with the narrowed section of the tube.

摘要： A valve component includes a first disk-shaped joining part and a second disk-shaped joining part. The first disk-shaped joining part has a first opening and has an elevation in a first region of the first disk-shaped joining part which runs at least partially peripherally around the first opening. The second disk-shaped joining part is joined to the first disk-shaped joining part and has a second opening which together with the first opening defines a channel for flow of a fluid medium therethrough. The second disk-shaped joining part further has a depression in a second region of the second disk-shaped joining part which runs at least partially peripherally around the second opening and which opposes the first region of the first disk-shaped joining part. The elevation interacts with the depression in sealing fashion.
