  • DIAPHRAGM HOLDER FOR AN OLEO-PNEUMATIC-TYPE SHOCK ABSORBER
    Publication number: 20220403904
    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.

  • DIAPHRAGM HOLDER FOR AN OLEO-PNEUMATIC-TYPE SHOCK ABSORBER
    Publication number: 20220364626
    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.

  • METERING NEEDLE FOR OLEO-PNEUMATIC-TYPE SHOCK ABSORBER
    Publication number: 20220364627
    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.
