  • Patent number: 4386869
    Abstract: Integrally sealed vibration dampening ball and socket joints having a spherical member capable of swivelling relative to a socket member. A split metallic or high strength plastic bearing ring disposed with clearance in a shell has a concave spherical surface portion in swivelling engagement with the ball member, and a pair of symmetrically disposed resilient rings installed between the bearing ring and the inner surface of the shell constantly urge the bearing surface of the bearing ring in engagement with the spherical member surface to prevent rattle and to compensate for wear. Normal loads are taken by the resilient rings, and overload and shock load are taken by the bearing ring. A bellows seal, formed integrally with one of the resilient rings or, alternatively, formed separate is fastened at one end in the shell. The bellows seal is held elastically at its other end around a portion of the spherical member.

  • Patent number: 4206690
    Abstract: In radial piston fluid handling devices, such as for example pumps or motors, piston shoes are pivotable connected to the respective pistons. The invention improves the swing-member portion of the piston shoe in order to increase the efficiency and pressure bearing capability thereby, that the endface of the pivot portion is formed part-cylindrically by a radius which is a little bit shorter than the radius of the associated piston. The fluid pressure balancing pocket in the pivot member becomes formed accordingly, so that the pressure bearing capacity of the piston-piston-shoe pivot-assembly becomes considerably improved.
