A modular electro-mechanical rotary valve (EMRV) designed to be installed and removed as a unit is provided. The modular EMRV includes a valve enclosure, at least one rotary valve body with at least one fluid pathway, and an actuator assembly. The valve enclosure, removably disposed within a mating cavity, includes a central axis, at least one inlet, at least one outlet, a hollow center, and at least one exterior seal interface to sealingly engage with at least one interior seal interface of the mating cavity. The at least one rotary valve body is disposed within the hollow center of the valve enclosure. The actuator assembly is engaged with an actuator interface of the at least one rotary valve body, providing rotational actuation. Various angular positions of the at least one rotary valve body are possible to manage fluid flow within a fluid system.

The antirotational, mechanical lash control mechanism for two reciprocating bodies having opposing cylindrical surfaces uses a radial U-shaped groove in the outer surface of the outer housing; a radial cut in the leg of said U-shaped groove, that extends from the groove into said bore; a U-shaped clip adapted to fit the U-shaped groove, the U-shaped clip having a ledge on a leg of U-shaped clip, where the ledge extends through said cut and into said bore; and a first stop on the outer surface of the inner housing, such that the first stop abuts said ledge to control mechanical lash between the outer housing and the inner housing. To prevent rotation, the ledge has a flat surface that mates to a flat surface on the inner housing.

The invention proposes a switchable support element () for a valve train of an internal combustion engine, said support element comprising a housing () in whose bore () an axially displaceable inner element () is received, a coupling means () extending in the inner element () can be brought partially into engagement with an entraining surface () of the housing () for achieving coupling, and said support element () further comprising at least one vertical stop means () that overlaps an annular groove () between the inner element () and the housing () for defining a coupling position of said coupling means () with coupling lash relative to said entraining surface (), the vertical stop means () is constituted by at least one thin-walled ring comprising a slot (), the ring is placed or slipped, slot () ahead, onto an outer peripheral surface () of the housing () to extend parallel to a transverse plane of the support element (), the housing () comprises at least one aperture () through which an inner peripheral segment () of the ring extends, a longitudinal groove () extends in the outer peripheral surface () of the inner element (), and an underside () of the inner peripheral segment () comes to abut against a lower end () of said groove for defining the coupling position.
