ABSTRACT:
A percussion power tool apparatus includes a body relative to which an impacting tool is moved to effect an impacting operation, the apparatus further including an operating member by means of which an operating load is applied in an operating direction to the apparatus, a support structure for the operating member including a piston received in a cylinder, the operating load acting to move the piston inwardly of the cylinder whilst such movement is resisted by fluid pressure in the cylinder at one side of the piston, relative movement between the piston and the cylinder being permitted in response to vibrations arising in the body and/or impacting tool, by controlling fluid flow between the one side of the piston and a pressurised fluid support system.
