Title: Improvements in or relating to rotary vacuum pumps
IPC: F04C27/02
Filed: 1958-07-10
Abstract: 836,863. Rotary vacuum pumps. DUNKEL, M. M., [trading as LEYBOLD'S NACHFOLGER, E.]. July 10, 1958 [July 24, 1957], No. 22235/58. Class 110 (2). [Also in Group XXIX] In a rotary vacuum pump of the oil sealed and filled-type air is bled into the chamber 9 beneath the delivery valve 10 through the bore 18 of a tube 11a, 11 and the annular space 17. This air is entrained in, and increases the compressibility of, the fluid being pumped and thus reduces noise and shock at high vacua. The size of annulus 17 controls the amount of air admitted. Leakage back into the working chamber 2 is restricted by throttling means, which may comprise holes 8 or mechanical means such as ball valves. The life of valve 10 is normally limited by stop 14 on tube 11 but to relieve excess pressure valve 10, tube 11 and stop 14 can lift as an assembly against spring 19 until stop 14 abuts against stop 20.

The horizontal position of the cutting assembly 40 can be varied by sliding an arm 41 in a saddle 42 and the saddle can be swung about a pivot 44 under the control of a cam 46 to move the stylus into and out of operative position. The workpiece is mounted on a table 80, Figs. 7 and 11, which is moved along the X-axis by a stepping motor 90 and along the Y-axis by a hydraulic pneumatic motor 95. The grooves extend along the Y-axis, and after each groove is formed, the cam moves the stylus off the workpiece while the latter is stepped one groove width along the X-axis and returned to its starting position along the Y-axis. The tool holder 32 is also arranged to tilt the stylus in the X-Z plane after each groove is formed, in such a way that its inclination is a function of the distance of the groove from the centre of the workpiece. The vertical movement of the stylus to produce the groove depth variations is produced by an electric signal. e.g. from two coils 62, Fig. 8, through links 68 which are stiff longitudinally but flexible laterally. The vertical movement is slightly arcuate, the stylus being mounted on a cantilever spring 70, Fig. 9.
