Abstract

A valve-operating rocker-arm for internal combustion engines at least partially displaceable or deformable selectively from its operative position in its mounted condition on the engine without any removal, so as to move at least its portion co-operating with at least one valve away from the clearing space and the path of travel for taking each associated valve out when removing same, releasable locking means being provided to prevent such a displacement or deformation in normal service or use.
