Abstract

1, 243, 820. Moving measuring feelers. ROBERT BOSCH G. m. b. H. Sept, 20, 1968 [Sept. 22, 1967], No.44715/68. Heading G1M. A movable measuring feeler (not shown) is pressed against a test piece by movement of a thread 14 which is pulled when compressed air controlled by regulator 12 and pressed into space 11 acts on the end of the differential piston portion 3b and moves the whole piston 3a, 3b, 3c to the left. The piston is supported by compressed air bearing nozzles 5 and the end chambers 7 and 8 are vented to atmosphere by way of passages 9.
