1,109,390. Linkwork; seals. COMMISSARIAT A L'ENERGIE ATOMIQUE. 16 March, 1967 [29 March, 1966], No. 12408/67 Headings F2B and F2K [Also in Division Fl] In a mechanism for rotating a piston 6 about the axis of a shaft 18, rotation of the piston 6 about its own axis is prevented by a sleeve 30 having at one end teeth 28 which mesh teeth 26 on a stationary bearing housing 22 and having at the other end teeth 32 meshing teeth 34 on a sleeve 36 secured to piston 6. A crank 16 connects shaft 18 with a shaft portion 14 on which the piston 6 is rotatably mounted. A sleeve 38, integral with sleeve 30, has a spherical zone engaging a knuckle-joint 40 on the shaft 14. A sealing bellows element 24 is provided. In a modification, annular seals 46, Fig. 3, are disposed between the ends of sleeve 30 and sleeves 43, 45 secured to housing 22 and piston 6. The space between tube 30 and bellows element 24 may be filled by a neutral fluid. In a further modification, bellows elements 24a, 24b, Fig. 4, are anchored to the ends of sleeve 30. In the embodiment shown in Fig. 5, the ends of tube 30 are connected by diametrically opposed pins 52 to rings 54, 56 which are mounted by means of diametrically opposed screws 59 on the housing 22 and piston 6. In another modification, a ring 60, Fig. 6, has tongue and groove connections 62 . . . 65, located at right angles to each other, with the housing 22 and piston 6. |
