A partition member of an anti-vibration hydraulic mount includes a first channel and a second channel between the working chamber and the compensating chamber. The partition member includes a membrane secured in a receiving cavity. The membrane divides the receiving cavity into two sub-spaces separated fluidically from each other. The membrane comprises a closing device configured to have an open configuration, in which the closing device is spaced apart from the central opening, and a closed configuration, in which the closing device abuts against the central opening to close the central passageway.

A mechanism for mounting in ground, foundation or structure, to provide road, port, railway or similar passive safety for protection of the respective vehicles or structures, having at least one rigid element arranged as a side of a triangle whose basal side rests on the ground, with its first end at the apex of the triangle, its midpoint pivoted to an intermediate element, and with its second end pivoted with respect to at least one friction element; a friction dissipation member; at least one elastic element arranged with its axis in the direction of the degree of freedom; the at least one friction element and at least one rigid element are attached by a coupling element allowing sliding of each friction element perpendicular to the impact load when it compresses the elastic element.

A shock absorber includes a cylinder, a slider coaxially provided outside of the cylinder and movable in a direction along an axis of the cylinder, a first spring abutting against the slider and urging the slider in one direction along the axis, a second spring abutting against the slider and urging the slider in the other direction along the axis, a sleeve provided between the cylinder and the slider, a first restriction portion fixed to the cylinder and abutting against one end of the sleeve to restrict a movement of the sleeve in the one direction, a second restriction portion located outside of the cylinder and abutting against the other end of the sleeve to restrict a movement of the sleeve in the other direction, and a fixing member penetrating the sleeve in a radial direction to restrict a movement of the second restriction portion with respect to the cylinder.

A shock absorber includes a cylinder, a sleeve provided so as to surround the outer circumferential surface of the cylinder, the cylinder formed of a different material from a material for the cylinder, first and second springs provided along the outer circumferential surface of the sleeve, and a slider provided between the first spring and the second spring, and capable of being displaced in an axel direction. The materials for the cylinder and the sleeve are a combination of materials that causes corrosion due to a contact of either one of those with the other one of those. A corrosion inhibitor is provided which suppresses an occurrence of corrosion on the cylinder or on the sleeve. In one embodiment, the materials are metals.

The invention relates to an agricultural apparatus (1) for spreading material, such as fertilizers, plant protection products, or seed, comprising a distributor linkage (10) which can be folded on both sides, comprising a central part (11), where the central part (11) is connected in a rotationally fixed manner to the agricultural apparatus (2), two intermediate frames (12 a,b) connected to the central part (11) in particular by joints, two lateral booms (13 a,b) connected to the respective intermediate frames (12 a,b), and a damping assembly (19) for damping motions of the first boom (13 a) and the second boom (13 b) in the direction of travel of the agricultural apparatus (1), where the damping assembly connects the intermediate frames (12 a,b) to one another in particular independently of the central part (11), or where the damping assembly (19) connects the respective intermediate frames (13 a,b) to the central part (11).

A wear sleeve for a shock body is disclosed. The wear sleeve inner diameter (ID) that is larger than an outer diameter (OD) of a shock body. A wear sleeve OD that is smaller than a spring coupler ID, such that the wear sleeve will fit about the outside of said shock body and between the shock body and the spring coupler.

Described herein is a shock mitigation apparatus. The shock mitigation apparatus may be utilized in a marine environment, able to absorb shocks transmitted to a seat system from a structure to which the seat is affixed. The shock mitigation apparatus includes at least one leaf spring wherein the leaf spring is cantilevered at one end and pivoted at a distal end thereof, and wherein the pivoted end is free to articulate upon flexure of the leaf spring.
