Abstract

A valve disabling mechanism, which may be employed in internal combustion engines having a retarding mode of the compression-release type additionally to the normal powering mode, includes a tubular adjusting screw (310) affixed to a valve train mechanism (50), a tubular drive pin (324) coaxially disposed within the tubular screw (310) having radial ports (334) and an actuator pin (348) disposed in the tubular drive pin (324) and reciprocated in the drive pin. Locking balls (362) are disposed within the radial ports (334), which are moveable to engage the tubular driven screw (310) and the tubular drive pin (324) for conjoint movement in the normal powering mode and to disengage the tubular screw from the tubular drive pin to permit a reciprocating motion of the tubular screw relative to the tubular drive pin in order to disable or modify the normal motion of the exhaust valves in the retarding mode.
