Abstract: A rocker arm includes a first end including a substantially horizontal wall having a receptacle formed therein. A second end of the rocker arm is spaced from the first end and includes a substantially horizontal wall for engaging a valve stem. A pair of spaced substantially parallel vertical sidewalls extend between the first end and the second end. In one embodiment, the sidewalls define a width between the first end and the second end that is less than each of the widths of the first and second ends. In another embodiment, a transverse wall extending between the sidewalls is formed in the second end. In yet another embodiment, rocker arm alignment walls are formed in the second end independently of the sidewalls.

Abstract: The valve spring retainer includes a base having an outer periphery and a central aperture. The central aperture defines a center axis. At least two tabs extending radially from the base outer periphery relative to the center axis. Each of the tabs have a distal end including an axially extending lip for retaining a spring relative to the retainer.

Abstract: In some embodiments of the present invention, a lever is actuatable to unlatch a pawl when the lever is in an unlocked position. When the lever is in a locked position, lever actuation cannot unlatch the pawl. An over-center device coupled to the lever can be used to position the lever in its locked and unlocked positions. In these and other embodiments, the lever is moved away from the pawl when the lever is in a locked position and is moved closer to the pawl when the lever is in an unlocked position. In some embodiments, the lever is pivotable about a pivot point that remains in the same location with respect to the lever in the unlocked and locked positions thereof. Although not required, the pawl is preferably movable by the lever to its unlatched state after the partially or fully-actuated lever has been moved to its unlocked state.

Abstract: A key assembly for vehicle anti-theft security system includes a mechanical key having a through aperture for receiving a resistor pellet which is inserted in the aperture and mechanically secured by swaging or staking the key material adjacent the aperture to force key material into engagement with the outer perimeter of the resistor pellet.

Abstract: A key with a resistor pellet is assembled by mechanically inserting the pellet into a suitable aperture in the key and displacing a portion of the key material into the body of the pellet by compressing the key around the perimeter of the pellet in a swaging process. The pellet is automatically selected from a plurality of pellets having a plurality of distinctive resistance properties. The pellet is tested to determine conformance with a pre-selected resistance property prior to insertion in the key. After insertion and swaging of the pellet in the key, the resistance properties of the pellet are reconfirmed.
