Abstract

This disclosure relates to a percussion tool which includes a housing having a chamber reciprocally mounting a piston with first and second pressure ducts at opposite ends of the latter and a control duct therebetween as well as a return duct in fluid communication with the chamber at a point intermediate the points of entry of the first and second pressure ducts, the improvement includes movable valve means in the form of an annular open ended valve sleeve operative for alternately placing the inlet and pressure ducts in fluid communication in a first position and placing the first pressure and return ducts in fluid communication in a second position while at the same time maintaining fluid communication between the inlet and second pressure ducts and closing communication between the inlet and first pressure ducts. The valve sleeve includes both an annular collar and a circumferential groove associated with selected ones of the latter-mentioned ducts for imparting the reciprocal motion to the valve sleeve.
