Patent number: 10221729Abstract: 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.Type: GrantFiled: June 15, 2017Date of Patent: March 5, 2019Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 9926816Abstract: A switchable rocker arm for valve deactivation is provided for a valve train of an internal combustion engine. The switchable rocker arm includes a cam lever assembly, a valve lever assembly, and a hydraulically actuated coupling assembly that is radially arranged between the cam lever and valve lever assemblies. The coupling assembly includes a shuttle pin, a locking pin with a round or flat locking interface, and optional shuttle pin and locking pin sleeves. 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.Type: GrantFiled: June 30, 2016Date of Patent: March 27, 2018Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.
