Abstract (en)
[origin: EP1952952A2] The damper has a spring (5) located completely within an oscillating damping mass (4) with respect to an axial length of the spring. The spring is provided for axial compressive preloading of the damping mass against housing of a hand-held rotary-percussion power tool e.g. hammer drill. The damper is formed of a mirror symmetrical element. A damper housing (9) is secured on the power tool housing, where major portion of the mass is located within the damper housing. The mass is fixed axially displaceable within the damper housing. The damping housing has housing stops (12) for the spring.
