Abstract (en)
[origin: EP0962661A1] The valve (D) has a antagonistic spring (G) which contacts a first piston (K1) with a counterforce overcoming the force of the spring arrangement (F). The antagonistic spring is switchable by a counter piston (K3). The first piston operates an electrical switch (S) via a push rod (13) jutting out from a boring (2) in the valve housing (1). The switch is located on the front of the housing with its own housing (3). The push rod passes through the counter piston and the antagonistic spring. The switch is in signal connection with a control appts of a machine tool.
