Fluid input for spindle head has inner piston track made in one with support surface

摘要

The input (1) for at least one fluid has two centering devices (23, 24) to center its running tracks (43, 44) relative to the spindle casing (3) and a piston unit (15) shorter than the greatest inner or outer diameter of the piston (16). An adjustable sensor unit (60) is built into the input. The inner piston track (43) and the support surface (21) are made in one.
