Abstract

A valveless pneumatic hammer comprises a hollow casing (1) having a backhead assembly (2) at one end and a bit assembly (3) at the other, and a piston (13) reciprocable in the casing. There is a chamber divider (5) at the backhead end of the casing which co-operates with the piston for conducting fluid under pressure into alternate chambers (23), (26), one at each piston end, for reciprocation of the piston. The chamber divider is located within the casing by a locating split ring (6) which holds the chamber divider axially against the backhead assembly. The chamber divider also has a recess in the end thereof nearest the piston which together with a bore in this piston end, comprises the fluid chamber at this end of the casing. <IMAGE>
