ABSTRACT:
A multiple-spindle machine tool or a multi-speed transmission wherein the spindles or shafts carry several fluid-operated aggregates in the form of clutches, brakes and/or work clamping devices which receive pressurized fluid by way of axially movable spools mounted in or surrounding the respective spindles or shafts. The spools are movable axially by a stationary cam (in a machine tool) or by an indexible cam (in a transmission), and receive pressurized fluid which is admitted axially or radially, depending upon whether the spools are received in or surround the respective spindles or shafts.
