    Abstract: A rocker arm (25) adapted to engage a pair of cam lobes (15,17), the rocker arm having first (31) and second (33) sidewall portions, and being formed from a flat sheet metal blank (25B) having a nominal thickness (T). The sidewall portions (31,33) define fold regions (51,53) whereby, after each is folded over upon itself, and the rocker arm is formed to have the sidewall portions generally parallel to each other, the fold regions provide first (41) and second (43) cam contact surfaces, each having a width (W) substantially greater than the nominal thickness of the blank.

    Abstract: A valve control system including a camshaft having first and second cam profiles, the valve control system comprising a rocker arm assembly (11) including a first rocker arm (13) having a first cam follower (15) in engagement with the first cam profile, and a second rocker arm (17) having a second cam follower (23,25) in engagement with the second cam profile. The engine includes a fulcrum location (P) operable to provide a source of pressurized fluid, and the first rocker arm includes a latch member (47) moveable between latched (FIG. 6) and unlatched conditions. The latch member is biased toward the latched condition by a fluid pressure in a chamber (51), and the first rocker arm defines a fluid passage (55) having a first end (57) in open fluid communication with the pressure source, and a second end (59) in open fluid communication with the pressure chamber (51).

    Abstract: The invention is a valve deactivator assembly (15) for use in connection with a valve train of an internal combustion engine. In application, a pre-selected number of the engine cylinders would each be equipped with a deactivator connected to its intake engine valve. Upon driver selection or predetermined road conditions, sufficient lost motion would be introduced into the valve train so that the valve would remain closed and the cylinder deactivated as the engine is in operation. The deactivator has in its inner body (19) a latch assembly that is in a latched condition for normal operation of the valve train. When it is desired to retain the valve in the closed position and deactivate a cylinder, the latch assembly is caused to be moved to the unlatched condition by increase in the pressure of the engine oil. When the latch assembly is unlatched, significant lost motion is introduced into the valve train causing the valve to remain closed and the cylinder is deactivated.

    Abstract: A rocker arm assembly includes first and second rocker arms defining a pivot location. The first rocker arm includes, toward a first axial end thereof adjacent the pivot location, a fulcrum surface and, toward a second axial end thereof, a latch assembly including a latch member moveable between latched and unlatched conditions relative to a latch surface defined by an adjacent portion of the second rocker arm. The latch assembly further including a spring biasing the latch member toward one of the latched and unlatched conditions, and a pressure chamber operable to bias the latch member toward the other of the latched and unlatched conditions. The first rocker arm further includes a fluid passage having a first end in open fluid communication with the fulcrum surface and a second end in open fluid communication with the pressure chamber of the latch assembly.
