ABSTRACT:
The invention relates to a feeding device for a tool slide of a machine tool of a simple, compact and economical construction comprising an electro-hydraulic linear amplifier easily accommodated in the constructional space of a hydraulically operated tool slide. The valve housing is inserted into the piston rod on the side of the piston remote from the control valve means thereby allowing for a plurality of tool slides to be arranged in a very compact space. The valve means forms a cartridge which can be simply inserted into the cylinder chamber formed by the cylinder housing. The arrangement of the control valve means in the cylinder housing and the rigid connection between the motor and the piston result in compact design and in shorter conduits for the hydraulic fluid between the control valve means and the cylinder chambers thereby leading to a high rigidity of the feeding device.
