Abstract
A switchable valve bridge for an internal combustion engine is provided that includes an outer housing, an inner housing, a locking collar, and a first ramp. The outer housing includes two valve pallets configured to interface with two poppet valves. The inner housing is slidably disposed within the outer housing. The inner housing has a first locking latch configured to move radially relative to an actuation axis of the inner housing. The locking collar is configured to move axially via an actuation force applied to the locking collar in a first axial direction parallel to the actuation axis. The first ramp is disposed within both the first locking aperture and the locking collar. The first ramp is configured to be actuated by the locking collar such that axial movement of the first ramp causes radial movement of the first locking latch.
