The first body portion includes: a first bore; a second bore including a first orifice arranged to receive a pressurized fluid; and a second orifice arranged to expel the fluid. The locking assembly includes: a locking pin disposed in the first bore; and a shuttle pin engaged with the locking pin. The shuttle pin is displaceable transverse to the locking pin to: displace the locking pin in a first axial direction to contact the second body portion with the locking pin; and displace the locking pin in a second axial direction to disengage the locking pin from the second body portion. The second bore includes the second orifice; or the second bore does not include the second orifice and is in fluid communication with the second orifice.

A method of assembling a solenoid valve assembly is provided. The method includes supporting a shoulder of a valve housing against a flange of a metal ring. The method includes inserting at least one axially extending post of the metal ring through at least one slot of a mounting tab. The method includes deforming the at least one axially extending post of the metal ring to clamp the valve housing between the metal ring and the mounting tab, with the metal ring, the valve housing, and the mounting tab being captively secured with each other. The method includes positioning the mounting tab at least partially within an opening at an axial end of a solenoid housing. The method includes bending or otherwise deforming the outer wall at the axial end of the solenoid housing to retain the solenoid housing to the mounting tab, the metal ring, and the valve housing.

Staking ring for solenoid assembly

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.

Rocker shaft with de-aeration oil gallery segment

A hydraulic support element including a housing with a central bore and a bottom face that is provided on one axial end of the housing, a piston that is arranged in the bore of the housing, the piston is connected to a bottom closure so as to define a first pressure chamber and a second pressure chamber is defined between the bottom face and the bottom closure. A valve is provided between the first pressure chamber and the second pressure chamber to regulate a fluid connection between the pressure chambers, and a seal formed between the piston and the bottom closure with the bottom closure being affixed to the piston in a detachable manner.

Hydraulic support element

A switchable roller finger follower includes an inner lever, an outer lever pivotably mounted to the inner lever by a pivot axle, and a coupling device. The coupling device includes a coupling pin configured to move between a locked position in which the inner lever and the outer lever are connected together for movement in at least one direction and an unlocked position in which the inner lever is movable relative to the outer lever in the at least one direction. The coupling device also includes a spring configured to bias the coupling pin in the locked or unlocked position. A de-aeration flow path is formed between an oil passage and an opening for allowing air to move out of the oil passage, past the coupling pin, and exit through the opening. The de-aeration flow path switches between being open and closed based on a position of the coupling pin.

Switchable roller finger follower with integrated leakage path for de-aeration

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.

In a first, locked position, the rotational motion of a camshaft is translated to linear motion of an engine valve. In a second, unlocked position, the cam lever assembly rotates about the valve lever assembly, facilitating valve deactivation. A pivot joint arranged between the cam lever and valve lever assemblies facilitates an arcuate lost motion of the cam lever assembly. An integrated arrangement for one or more lost motion springs offers packaging and functional advantages.
