Systems for valve actuation in internal combustion engines provide configurations for collapsing valve train components, particularly collapsing valve bridges. Various configurations for locking a bridge piston to a bridge housing include substantially cylindrical locking pins that may be housed within a substantially cylindrical receptacles defined by a transverse bore in the bridge piston and actuated hydraulically and may include an actuating pin that interacts with the locking pins to synchronize motion and provide positive positioning within an annular recess in the bridge housing to lock or unlock the bridge piston for movement relative to the bridge housing. Various geometries for locking pins and actuating pins provide benefits of manufacturing, ease of assembly, alignment and reduced wear.

A stator assembly for receiving at least two rotors. The assembly comprises at least two individual stators which are divided into stator segments, with at least one segment being a shared segment which forms part of at least two adjacent individual stators. An engine valve actuation assembly includes a stator assembly comprising at least two individual stators. Each individual stator comprises a peripheral portion extending around the longitudinal axis of the stator, with part of the peripheral portion of each stator forming part of the peripheral portion of an adjacent individual stator. Methods for assembling a stator assembly are also described.
