    摘要： Invention relates toa piston pinassembly for an internal combustion piston engine, in which piston pinassembly the first and the second ends(14.1, 14.2)having a common first central axis(14.4)and the center area having a second central axis (14.6) which axes are offset at a distance from each other. The assembly comprises a mechanism which includes at least a first setting and a second setting, in which first setting the mechanism locks the position of the second central axis (14.4)in respect to the first central axis and in which second setting the mechanism actuates a change in the position of the second central axis in respect to the first central axis when in use and assembled to a cranking or operating internal combustion piston engine.

    摘要： The invention relates to an elastic fixing element for a piston (2) of a variable compression ratio engine (10), said fixing element consisting of at least one metal rod (15) held under tension between the piston (2) and the transmission member (2) and applying a strong contact pressure between the base of the piston (2) and the upper face of the transmission member (3), said piston (2) being tightened according to a previously calculated angle enabling the metal rod (15) formed by a dowel (16) to be subjected to a desired tension strain and enabling the tightening pre-stress to be reached between the piston (2) and the transmission member (3), and indexed in rotation in relation to the transmission member (3) by an additional tightening which does not significantly increase the tightening pre-stress, said dowel (16) continuing to extend under the same tension strain by plastic deformation.

    摘要： A cast metal connecting rod of the type used in a reciprocating piston engine has a beam section between two end sections. The beam section and the end sections are integral with one another and are at least partially made of a cast metal material. At least the beam section of the connecting rod includes an insert made of a sintered powder metal material. The insert is at least partially encapsulated by the cast metal material of the connecting rod. The insert reinforces the connecting rod and can help match characteristics of surrounding or mating parts of the engine that are made of materials more similar to the material of the insert than the cast metal of the connecting rod. The cast metal material, for example aluminum alloy, of the connecting rod can also provide localized regions of high machinability where needed.

    摘要： A connector assembly (46) comprises a housing (60) and a tensile member (62) disposed within the housing (60). The tensile member (60) comprises first and second end portions. Each end portion sealingly engages the housing (60) to form a hydraulic chamber (72) therebetween. A first connector (64) is pivotally coupled to the first end portion. The axial position of the first connector (64) relative to the housing (60) is controlled by pressure within the hydraulic chamber (72).

    摘要： A curved, tetrahelix bicycle crank arm composed of a helical array of tetrahedra is disclosed. This design will transmit the propelling force away from the top dead center point providing more efficient use of the propelling energy. With this tetrahelical design a hollow core is possible that will reduce weight and permit lubrication if needed without reducing strength. This design is also applicable to the connecting rod of internal or external combustion engine.
