Abstract: A hollow rocker shaft including a central opening defined by a radially inner surface and a separator secured in the central opening of the rocker shaft is provided. A radially outer surface of the separator engages the radially inner surface of the rocker shaft via a press-fit. The separator divides the central opening of the rocker shaft into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The separator includes an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber.

Abstract: A fluid diverter including a cylindrical body and an extension arm is provided. The cylindrical body defines a first fluid passage extending from a first axial end of the cylindrical body and a second fluid passage circumferentially offset from the first fluid passage and extending from a second axial end of the cylindrical body. A seepage orifice is defined in the cylindrical body providing a fluid communication path between the first axial end and the second axial end. The extension arm extends from the cylindrical body and includes a locating receptacle dimensioned to receive a fixing element to rotationally and axially fix the fluid diverter.

Abstract: A method of manufacturing outer arms of a three arm spring over pivot switchable roller finger follower. The method includes the steps of forming the outer arms of the switchable roller finger follower as a single unit, forming a material web between the outer arms, and separating the outer arms apart from each other. Also, an intermediate assembly of the outer arms of the three arm spring over pivot switchable roller finger follower is disclosed. The intermediate assembly has a first outer arm, a second outer arm, and a material web which extends between the outer arms, and adjoins the outer arms together.

Abstract: A switchable valve train assembly including a carrier housing defining a hydraulic circuit, a supply assembly, a plurality of rocker shafts, a plurality of separators, and a plurality of rocker arm assemblies is provided. Each one of the plurality of separators divides the rocker shafts into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The plurality of separators each include an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber. Locking assemblies of the rocker arm assemblies are selectively actuated based on the supply assembly. The separators ensure that hydraulic fluid within the hydraulic fluid is de-aerated and that the second chambers remain primed with hydraulic fluid for faster actuation of the locking assemblies.

Abstract: A switchable roller finger follower including a combined lost motion spring and hydraulic lash adjuster clip is provided. The switchable roller finger follower includes at least one spring having two coiled spring portions. Each of the two coiled spring portions is wrapped around a respective spring holding pin formed on an inner elongated body. Each one of the at least two coiled spring portions includes a first leg and a second leg. The first legs each extend from a respective one of the two coiled spring portions to engage a spring pallet formed on an outer elongated body. The second legs each contact a bottom portion of the inner elongated body in proximity to a socket portion to act as a retainer for retaining a hydraulic lash adjuster to the inner elongated body.
