Abstract: A distributed load bearing including a roller, an inner flex ring, a pin and a load distribution spring. The inner flex ring is positioned radially inwards of the roller, and the pin is positioned radially inwards of the inner flex ring, and the load distribution spring is positioned in a cavity defined by the pin and the inner flex ring. The load distribution spring is preloaded, so as to apply a force to the pin and so as to apply a plurality of radially outward forces to the inner flex ring.

Abstract: A distributed load bearing including an outer flex ring, a load distribution spring, and a retainer. The outer flex ring is configured to be positioned radially outwards of a shaft. The load distribution spring is preloaded and positioned radially outwards of the outer flex ring. A radially inner surface of the load distribution spring contacts the outer flex ring. The radially inner surface is an arc defined by a first radius when the load distribution spring is in a lower load distribution mode, and a second radius when the load distribution spring is in a higher load distribution mode. The retainer is positioned radially outwards of the load distribution spring, and the retainer angularly and radially positions the load distribution spring.

Abstract: Valvetrain of an internal combustion engine, including a rocker support, a fulcrum, and a rocker. The rocker support is mounted to a cylinder head and fixed relative thereto. The rocker is positioned about the rocker support and partially in an axial aligning groove of the rocker support. The fulcrum is sandwiched between the rocker support and the rocker. The rocker oscillates about the fulcrum as forces are received and applied to a first and a second end of the rocker.

Abstract: In a compression release engine retarder of the type in which the reciprocating motion of a hydraulic piston in the retarder is coupled to arcuate motion of a point on a pivoting element in the associated engine by a push rod between the piston and the pivoting element, the end of the push rod in contact with the piston is made convex and the piston surface contacted by the push rod is made flat so that the convex push rod surface rolls on the flat piston surface. This rolling motion replaces sliding motion in the prior art, thereby reducing or eliminating the need for expensive surface treatments and/or lubrication.

Abstract: A thermal actuator includes a housing containing a stack of deformable discs. A spring maintains a movable follower in engagement with the disc at the end of the stack. At least some of the discs are active snap-acting thermostatic bimetallic discs with first and second structural states wherein those discs are concave in first and second directions at different temperatures. The stack includes a first kind of bimetallic disc which snaps between its structural states at lower transition temperature and a second kind bimetallic disc which snaps between its structural states at a higher transition temperature. The first and second kinds of discs are alternately arranged in the stack. In one embodiment, passive discs which remain in a single structural state are disposed between adjacent pairs of the active discs.
