Abstract
1,234,681. Telemotors. H. KARRENBERG [trading as HUGO KARRENBERG & SOHN K. G] Feb. 10, 1969 [Feb. 13, 1968], No. 7003/69. Heading F1P. The power cylinder 28 of a telemotor system 28, 16, 17 has a pin 20 exposed to the fluid-pressure and biased by a lever 21 acting on a switch 22 arranged to switch of the drive to operating cam 1 on excess pressure in the system. A make-up supply of fluid from tank 12 enters at 15 at the beginning of the working stroke if any fluid has been vented by pressure relief valve 24.
