  • Publication number: 20240149329
    Abstract: A method for forming and installing a retaining ring comprises: feeding a wire in a linear path into a forming die having a circular bore; forming, using the forming die, the wire into a formed ring having a ring shape; transferring the formed ring from the forming die to a transfer puck; and installing the formed ring, as a retaining ring, in a tube of a product assembly. The formed ring is maintained in a constrained state between forming in the forming die and installation in the product assembly. A system for forming and installing a retaining ring into a product assembly includes a forming die configured to form a wire into a formed ring having a ring shape; and a transfer puck to transfer the formed ring from the forming die. The formed ring is maintained in a constrained state from forming through installation.

  • Patent number: 11613239
    Abstract: A pressure supply unit for a brake system including a booster body that defines an axially extending cylinder. A piston is slideable within the cylinder. The piston defines a bore that receives a spindle. The spindle is rotationally fixed and axially moveable for providing the axial movement of the piston. A motor is positioned about the spindle and is configured to axially translate the spindle and piston. A ball and socket joint connects the piston and spindle while accommodating pivoting movement of the spindle. The ball and socket joint includes a ball at a front end of the spindle and a socket in the bore of the piston which receives the ball.

  • Patent number: 6705083
    Abstract: The subject invention provides a master cylinder having a compact profile. In particular, the master cylinder comprises a hollow body having a continuous outer wall with a continuous thickness. An end wall is integrally formed with the outer wall at a first end to close an end of an integrally formed bore. A number of apertures are formed within the outer wall to provide fluid communication between the outer wall and the bore. A flange is also integrally formed with the outer wall at a second end to define a fully integrated master cylinder. The outer wall further includes thickened sections extending between an inner surface of the bore and a mounting surface with the thickened sections being at least 30 percent smaller than the inner diameter of the bore for providing the compact profile of the integrated master cylinder.
