Definitions

the invention is based on the object Generic protection device in such a way that they prevent the ingress of contaminants following the Impact tool guidance in the direction of the percussion piston prevented.
the housing 2 has two longer bore sections 2a and 2b which merge into one another via a short, narrowed bore section 2c.
a striking tool guide is fastened in the housing 2 for movably supporting the chisel 3 and, viewed in the opposite direction to the striking direction (arrow 1), is composed of an outer guide section 5a and an inner guide section 5b spatially separated therefrom.
two oval-like holding elements 6 are also fixed in place, which limit the freedom of movement of the chisel 3 in the direction of impact (arrow 1), ie to the left in the illustration.
the drawing also shows that the diameter of the sealing lip 7b in the installed state is larger than the diameter of the impact surface 3a: the latter merges with the formation of a truncated cone section 3f into the counter surface 3e having a larger diameter. Due to the design of the counter surface 3e and the truncated cone section 3f relative to the bounce ring 9, the chisel 3 can only assume a retracted end position in the opposite direction to the direction of impact (arrow 1), in which the impact surface 3a is at the level of the bounce ring 9 and in front of it narrowed bore section 2c is located. In order to ensure that the sealing lip 7b is supported only on the wear-free counter surface 3e, the freedom of movement of the chisel 3 is dimensioned shorter in the axial direction than the length of the counter surface 3e run over by the sealing lip.
