Abstract
912,694. Copy-turning. LOEWE & CO. A.G., LUDW. May 24, 1960 [May 26, 1959], No. 18348/60. Class 83 (3). In a tracer-controlled machine-tool a slidevalve 8 associated with a tracer 9 is provided in the discharge 13 from the low-pressure side of a working cylinder 4, and a loading valve 20 in the pipe 17 from the high-pressure side to the low-pressure side which determines the pressure on the high-pressure side. Movement of the tracer 9 varies a gap 12 to vary the pressure in the cylinder space 4a and on the loading valve face 20b. The space 4b is supplied with pressure from a pump 16 which pressure also acts on a face 20e of the valve 20 against the opposition of springs 20c. The position of the tool slide cylinder 1 is thereby controlled. A safety valve 19 is provided. In a modification, two loading valves are provided, one of which only is selected by a lever 23, Fig. 2, connected to a valve 22. In a further modification, the loading valve 24, Fig. 3, has two steps 24<SP>1</SP>, 24<SP>2</SP> and the compression of the springs 20a is adjusted by a lever 23 which moves a cam 27 as well as a selector valve 22a.
