Abstract

The invention relates to a boring ram with a pneumatically driven striking piston (16), movable in the axial direction in a reciprocating manner in a housing (12), and a control device which has a control part (22) movable with the striking piston and a control part (14) interacting with the control part (22) and held on the housing (12) and controls the admission of pressure to the striking piston. In order to permit a short overall length of the boring ram, the movable control part is designed as a control piston (22) which projects axially from the striking piston (16) and plunges into an opening (24) of an end piece (14) forming the control part on the housing side. <IMAGE>
