PISTON SPHERIQUE POUR COMPRESSEURS OU MACHINES SIMILAIRES

In a spherical piston (6) for compressors or the like, the spherically designed outer face (11) of the spherical piston (6) swings to and fro in the cylindrical bore (3) of a compression volume (13) filled with flow medium, the compression volume (13) being formed between an end face (12) of the sph...

Zusammenfassung:	In a spherical piston (6) for compressors or the like, the spherically designed outer face (11) of the spherical piston (6) swings to and fro in the cylindrical bore (3) of a compression volume (13) filled with flow medium, the compression volume (13) being formed between an end face (12) of the spherical piston (6) and a delimiting wall (5) in the cylindrical bore (3) lying axially opposite this end face (12). In order to be able to produce the spherical piston (6) economically for various applications, with the compression volume (13) having a different size and shape, the spherical piston (6) consists of a piston body (7), of a closed ring (9) arranged in an annular recess (8) of the piston body (6) and having the spherical outer face (11), and of a cap (10) which is secured on the piston body (7), forms the end face (12) of the spherical piston (6) and lies tight against the ring (9) at least on its side surface (15) directed axially towards the compression volume (13). PISTON SPHERIQUE POUR COMPRESSEURS OU MACHINES SIMILAIRES DONT LA SURFACE EXTERIEURE SPHERIQUE GLISSE EN VA-ET-VIENT DANS L'ALESAGE CYLINDRIQUE D'UNE CHAMBRE DE COMPRESSION FORMEE ENTRE LA FACE FRONTALE DU PISTON SPHERIQUE ET UNE PAROI DE DELIMITATION DE L'ALESAGE CYLINDRIQUE.POUR PERMETTRE UNE FABRICATION ECONOMIQUE DU PISTON SPHERIQUE EN VUE DE DIFFERENTES APPLICATIONS, AVEC DIFFERENTES DIMENSIONS ET FORMES DE LA CHAMBRE DE COMPRESSION, LE PISTON SPHERIQUE SE COMPOSE D'UN CORPS DE PISTON 7, D'UN SEGMENT OU ANNEAU FERME 9 LOGE DANS UNE CAVITE ANNULAIRE 8 DU CORPS DE PISTON ET PRESENTANT UNE SURFACE EXTERIEURE SPHERIQUE, ET D'UN CHAPEAU 10 FIXE SUR LE CORPS DE PISTON ET CONSTITUANT LA FACE FRONTALE DU PISTON, LEDIT CHAPEAU ETANT EN CONTACT HERMETIQUE AVEC LE SEGMENT, AU MOINS SUR LA SURFACE FRONTALE DE CELUI-CI TOURNEE VERS LA CHAMBRE DE COMPRESSION.
