Abstract (en)
The generator (1) includes a control device having a reciprocating control piston (3) set within a reciprocating working piston (2) set inside a housing (20). The working piston divides the housing interior into two pressure chambers (11,12). The two pressure chambers alternately receive working fluid during the reciprocating of the working piston. An independent claim is also included for a construction apparatus.
