摘要

The tool assembly (10a) has guide unit (14a) and rotary valve (16a) which are mechanically coupled with each other. The rotary valve is provided for controlling pressure of pressure chambers (18a) provided in guide unit. The guide unit is provided with receiving area (28a) for holding switching element (30a) of valve. The switching element is controlled by control disc (32a) provided with control element (34a). The valve drive element (42a) is integrated into rotary valve. The high and low pressure storage elements (44a,46a) are connected to pressure chamber by valve. An independent claim is included for portable power tool.
