    Abstract: A one-way ratchet overrunning clutch includes first and second concentric races, the first race having pockets configured to contain pawls, each pocket including a boss having an exterior convex surface defining an arc of about 180°. Each pawl is supported on one boss, and is adapted to ratchet about the boss to selectively lock the races together. Each pawl has a J-shaped body including a pair of legs joined by a hook portion that with one of the legs defines a concave surface. The concave surface is configured to partially engage a complementary exterior convex surface of a corresponding boss, and the concave surface defines an arc ranging from 90° to at least 150° adapted to circumscribe an identical range of the convex surface of the corresponding boss. The interactive convex and concave surfaces of respective pawl and boss elements provide an effective pawl retention system under centrifugal forces.

    Abstract: A hydraulic component includes a piston and a cylinder with a piston receiving space in which the piston is displaceably arranged while defining a chamber, via which a pressure may be applied to a first end face of the piston, from a control chamber, via which pressure may be applied to a second end face of the piston which faces away from the first end face. A first hydraulic line and a second hydraulic line open into the chamber and a control line, which branches off from the first hydraulic line, opens into the control chamber. Due to the respective pressure ratio between the pressure in the chamber and the control chamber, the piston is displaceable from a closed position, in which the first and second hydraulic lines are fluidly decoupled, into an open position, in which the first and second hydraulic lines are fluidly connected, and vice versa.
