Abstract: Shown is a latch pin for use in a valve lifter and a valve lifter including the same. The latch pin for selectively latching within a pin chamber provided in the valve lifter is configured as a whole as a cylindrical pin with one end in the shape of a spherical crown, wherein a stepped flat is formed on radially one side of said one end and is dimensioned to be received within the pin chamber to engage with an axial latching surface thereof. On the top side of said one end, a first relief is formed by beveling the spherical crown, and on the radially other side opposite to the stepped flat across said first relief, a second relief is formed by beveling the spherical crown, wherein the second relief radially adjoins the first relief and circumferentially adjoins a remaining pin face in the shape of the spherical crown.

An inner arm assembly comprises a latch arm. A first spring prop is on the inner arm assembly distal from the latch arm. An axle joins the inner arm assembly to pivot between the first outer arm and the second outer arm. A spring is biased against the first outer arm and against the first spring prop. The first spring prop can comprise a hooked end. Or, the first spring prop can extend laterally out from the rocker arm and parallel to the axle. The spring can comprise a one-piece spring comprising first and second coil springs connected by a lateral connector. Or, two separate torsion springs can comprising tangential spring ends extending at approximately 90 degrees.

Abstract: A rocker arm comprises a first outer arm and a second outer arm joined by a pivot body, the first outer arm comprising an inner side, the inner side comprising a limiting surface. An actuatable latch mechanism is within the pivot body. A first inner arm and a second inner arm are joined by a latch arm. An axle joins the first inner arm and the second inner arm to pivot between the first outer arm and the second outer arm. A second axle is between the first inner arm and the second inner arm. A pin extends from the second axle towards the first outer arm, and the pin is configured to pivot towards and away from the limiting surface when the first inner arm and the second inner arm pivot between the first outer arm and the second outer arm.

Abstract: A lost motion mechanism can comprise a castellation device, comprising a casing, an upper castellation, and a lower castellation. The casing can comprise a first linear slot and a second linear slot perpendicular to the first linear slot. Upper castellation can comprise an upper body, spaced upper teeth extending from the upper body, the spaced upper teeth forming spaced upper gaps therebetween, and an actuation peg extending from the upper body into the first linear slot. Lower castellation can comprise a lower body, spaced lower teeth extending from the lower body, the spaced lower teeth forming spaced lower gaps therebetween, and an anti-rotation peg extending from the lower body into the second linear slot. An actuator can be configured with the lost motion mechanism so that a movable arm comprises a forked end configured to move on the actuation peg as the movable arm swivels.

Abstract: An overhead cam engine system comprises a rotating overhead exhaust cam rail comprising a plurality of exhaust lobes. A first switching roller finger follower actuates a first exhaust valve, and is configured to switch between a first lift profile and a second lift profile. A second switching roller finger follower is coupled to actuate a second exhaust valve, and is configured to switch between a third lift profile and a fourth lift profile. The third and fourth lift profile are different than the first and second lift profile. An actuation assembly is connected to switch the first switching roller finger follower and the second switching roller finger follower to select between at least three exhaust lift modes to open and close the first exhaust valve and the second exhaust valve using combinations of the first, second, third and fourth lift profiles.

Abstract: A rocker arm can comprise a forked outer arm assembly and a T-shaped inner arm assembly comprising an inner arm body comprising a valve side, a latch side, a bearing hole on the valve side, and a latch body on the latch side, the latch body comprising inner arm extensions extending away from the latch body. A pivot axle can connect the outer arm assembly to the inner arm assembly so that the inner arm assembly is configured to pivot with respect to the outer arm assembly. A latch assembly can comprise a latch configured to selectively extend to and retract from a latch seat on the latch body to selectively lock the inner arm assembly with respect to the outer arm assembly or unlock the inner arm assembly to pivot within the outer arm assembly.

Abstract: A switching roller finger follower (SRFF) for valve actuation includes an outer arm (16), a first inner arm (12), a bearing axle (50) and a latch pin (26). The outer arm (16) is formed of a metal stamping, and is pivotally coupled to a main axle (40). The first inner arm (12) is coupled to the main axle (40) and is pivotably secure to the outer arm. The bearing axle (50) extends through the outer arm and the first inner arm. The bearing axle supports a roller (20) thereon. The latch pin (26) is slidably disposed in the outer arm (16) and is movable between at least a first position where the outer arm (16) and the first inner arm (12) are coupled for concurrent rotation and a second position wherein one of the outer arm and the first inner arm are configured to rotate relative to the other arm.
