Resonator with cavities together with thermal compensation device

In at least one cavity of the resonator is arranged an electrically conducting metal disc 1 whose periphery does not contact the lateral wall of the cavity, the said disc 1 being mounted on a disc 3 of a material which can expand with temperature, this second disc 3 being fixed rigidly to the walls...

Summary:In at least one cavity of the resonator is arranged an electrically conducting metal disc 1 whose periphery does not contact the lateral wall of the cavity, the said disc 1 being mounted on a disc 3 of a material which can expand with temperature, this second disc 3 being fixed rigidly to the walls of the cavity in such a way that the expansion of the disc 3 under the effect of temperature displaces the disc 1 axially inside the cavity. The resonator according to the invention is used in particular in the telecommunications equipment on board spacecraft. DANS AU MOINS UNE CAVITE DU RESONATEUR EST DISPOSE UN DISQUE1 EN METAL ELECTROCONDUCTEUR DONT LE POURTOUR NE SE TROUVE PAS EN CONTACT AVEC LA PAROI LATERALE DE LA CAVITE, LEDIT DISQUE1 ETANT MONTE SUR UN DISQUE3 EN MATIERE DILATABLE AVEC LA TEMPERATURE, CE SECOND DISQUE3 ETANT FIXE RIGIDEMENT AUX PAROIS DE LA CAVITE DE TELLE MANIERE QUE LA DILATATION DU DISQUE3 SOUS L'EFFET DE LA TEMPERATURE DEPLACE LE DISQUE1 AXIALEMENT A L'INTERIEUR DE LA CAVITE.LE RESONATEUR SELON L'INVENTION EST UTILISE NOTAMMENT DANS LES EQUIPEMENTS DE TELECOMMUNICATIONS A BORD DE SPATIONEFS.
