摘要：
The present invention relates to a valve (20) intended to be mounted in a holder (10) of a tool (11) for cutting of solid materials, said valve (20) being activated by axial displacement of the tool (11) in the holder (10), said valve (20) including a valve housing (26), a push-rod (27) axially displaceable in the valve housing (26) and acting upon a sealing body (35) of the valve (20).
Valves of the type specified above are normally secured in holders for the tools by thread connections. However, this structural design involves certain structural disadvantages, e.g. concerning the forces acting upon the valve.
The characterizing feature of the present invention is that the valve (20) according to the invention has a floating suspension in the holder (10).
