Abstract
A fluid actuator housing (40) supports an output member 56 and a valve assembly (62). The valve assembly controls fluid communication to a pair of chambers (58, 60) to reciprocate the output member within the housing. The first part (64) of the valve assembly directs fluid communication to the chambers and the second part (66) is engageable with the output member to control movement of the first part.
