Abstract (en)

[origin: DE19830979A1] A working device, especially a ramming device for compacting soil, comprises a housing (3) which belongs to an upper mass, and has a working mass which can be linearly driven back and forth with regard to the upper mass. The working mass is linearly guided via a guide cylinder (20) which is fastened to the housing (3) with elastic mobility. The transfer of bounce impacts acting upon the working mass to the upper mass can be effectively reduced by the elastic mobility of the guide cylinder (20) with regard to the housing (3).
