Abstract: A method for manufacturing a diaphragm holder for a shock absorber of the oleo-pneumatic type, in particular for an aircraft landing gear. The diaphragm holder includes a first end with a dome, and a tubular portion extending from the dome to a second end. The method includes a step of overmolding a first material onto an insert. The insert can be a second material with a value of compression breaking stress divided by density that is higher than the first material or alternatively, of a material identical to the first material. A diaphragm carrier which can be manufactured by this method.

Abstract: A tooling for winding a fibrous fabric on a support, allowing gradual modification of the shape of the support as winding progresses, and includes compaction devices to reduce wrinkling of the fabric obtained after compaction.

Abstract: A diaphragm holder for an oleo-pneumatic-type shock absorber includes a tubular body made of thermoplastic material, having a first end arranged to hold a diaphragm provided with flow restricting orifices and an opposite second end defining an arched bottom for withstanding pressure forces. Each of the two ends is provided with a localised mechanical reinforcement element forming an axial stop arranged to allow tensile stressing of the tubular body.

Abstract: A metering needle for an oleo-pneumatic-type shock absorber includes a base made of thermoplastic material, from which projects a rod arranged to control the flow of a hydraulic fluid through an orifice. The base has an arched bottom for withstanding pressure forces, in which is mounted an insert arranged to mechanically reinforce the arched bottom and distribute the pressure forces evenly.

Abstract: A diaphragm holder for an oleo-pneumatic-type shock absorber includes a tubular body made of thermoplastic material, having one end arranged to hold a diaphragm and an opposite end defining an arched bottom for withstanding pressure forces. An insert is housed in the bottom of the tubular body and is arranged to mechanically reinforce the bottom and to distribute the pressure forces evenly.
