<p>A control apparatus for a first and a second tool (1, 2) operated by means of a pressure medium, in particular hydraulic oil, includes a first supply circuit (3) for the first tool (1) and a second supply circuit (4) for the second tool (2). The control apparatus can be connected to a first pressure line (20) and to a second pressure line (21) of a control device to be operated manually, by which control device the flow rate at the first tool (1) and at the second tool (2) can be changed. The novel control device includes a control valve (7) provided jointly for the first and second supply circuits (3, 4) as the control device, the control valve (7) has three switching positions: (a) the flow rate from the first pressure line (20) is available only to the first tool (1) and the flow rate from the second pressure line (21) is available only to the second tool (2), (b) the flow rate from the first and second pressure lines (20, 21) is available to the first tool (1), (c) the flow rate from the first and second pressure lines (20, 21) is available to the second tool (2).</p> |
