Hand Machine Tool Striking Mechanism Unit

摘要

A hand-held power tool hammer mechanism, having a hammer device ( 10 a- 10 k), which can be driven by means of a piston ( 12 a- 12 k) via a gas volume ( 14 a- 14 k). A hammer mechanism characteristic value (Sa-Sk), which is composed of the maximum hammer device surface dimension ( 16 a- 16 k), cubed and divided by the hammer device mass ( 18 a- 18 k), is greater than 200 mm³/g, preferably greater than 220 mm³/g, and particularly preferably greater than 240 mm³/g.
