Spring retainer

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.

Engine rocker arm

A latch assembly having at least one control element having a first path of motion in which a ratchet is moved to an unlatched position and a second path of motion in which the ratchet is not so moved, the path of motion taken by the control element dependent upon whether an engagement element is engaged with the control element or disengaged therefrom. Preferably, the control element moves the ratchet by contact with a pawl which itself can be engaged with the ratchet. In a preferred embodiment of the present invention, the control element can be partially or fully actuated through its second path of motion while still being engagable with its engagement element. If already partially or fully actuated through its second path of motion, the engagement element is preferably movable into contact with the control element and can move the control element to its first path of motion. The latch assembly can have a second control element also having first and second paths of motion determined at least partially upon whether an engagement element is engaged with the second control element or disengaged therefrom. The second control element can be connected to the first engagement element to move the first engagement element into and out of engagement with the first control element when the second control element is actuated in its engaged state.

Latch apparatus and method

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.

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.

Key assembly for vehicle anti-theft security system

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.
