Abstract

A pneumatic impact breaker which comprises a housing (11) with a rear cylinder head (12), one or two handles (18, 19) and a longitudinal cylinder bore (20), a hammer piston (28) reciprocably guided in the cylinder bore (20), a front portion (55) of the housing (11) including socket means (13, 17) for receiving the rear impact receiving end (15) of a working implement (16), an air distributing valve (26, 27) located in the rear part of the cylinder bore (20) and arranged to direct motive pressure air alternatingly to the opposite ends of the hammer piston (28) to make the latter reciprocate in the cylinder bore (20), and the rear cylinder head (12) comprises a plug extending into the rear end of the cylinder bore (20) and forming an axial support for the air distributing valve (26, 27), whereby two parallel wall portions (29, 30) extend rearwardly from the housing (11) and which together with a transverse wedge bolt (32) form a mounting means for said cylinder head (12) and said handles (18, 19).
