The invention is a unique air inlet control system for a distributor of a jack-hammer wherein the inlet control valve is mounted in the inlet passage so as to be pivotally movable by a sliding rod which is in intimate contact with the control trigger mounted in the handle as well as the valve body. The arrangement permits any force that is applied to the control trigger to be translocated to the valve body and thereby unseat the valve body. Further, when the force is removed from the control trigger, the compressed air acts on the sliding rod to allow the valve body to return to a sealed position.

A compressed air distributor system utilizing a source of compressed air for powering hand operated air equipment, said distribution system comprising: a handle housing having a first passage and a recessed portion; an annular member mounted coaxially in said first passage, said annular member having a second passage therethrough and means for sealing said first passage; pivot valve means sealingly mounted in said second passage for selectively opening and closing said second passage; said pivot valve means further comprising a valve body having a trunconical outer configuration with a central counterbore, said valve body further having a base diameter at one end and a reduced diameter at the opposite end with a circular lip extending axially in one direction from said base diameter and located concentric to said central counterbore, said circular lip defining a valve seat, said trunconical outer configuration further having axial grooves radially spaced and beginning at said base diameter and extending in an opposite direction toward said reduced diameter, said valve body further being mounted in said second passage of the annular member for selectively opening and closing said second passage; control means mounted in said recessed portion, said control means being mounted in said recessed portion to move from a predetermined first position to a predetermined second position; means for translocating interposed said pivot valve means and said control means, said translocating means further being mounted in intimate contact with said control means and said pivot valve means such that when said control means is at said predetermined first position, said translocation means communicates with said pivot valve means to seal said first passage, and when said control means is at said predetermined second position, said translocation means communicates with said pilot valve means to open said first passage means permitting said source of compressed air to pass to the distributor.
