Abstract

The invention concerns an apparatus in a metal working machine for controlling the movement of a work tool.The apparatus is simple in design and construction and enables safe and functional automatic control of the tool.The apparatus includes a valve unit (2), which is situated in a piston cylinder housing (1) and which includes a valve body (26) which is designed to be automatically moved by fluid pressure to an initial position, where there is reduced communication between two chambers (8 ad 10) situated one on each side of the valve unit (2) in the housing (1), and in which situation, the tool is enabled to be moved at the required working speed, and also to a second position, where there is enlarged communication between the chambers (8 and 10) and the tool is enabled to move at a fast working speed.<IMAGE>
