Abstract
1343738 Valves SIEMENS AG 19 April 1971 [25 March 1970] 25459/71 Heading F2V A pinch-cock comprises a silicone rubber tube 1 squeezed by a part 4 of a lever 3 pivoted at 5. The lower end of the lever 3 is carried in a spiral groove 7 which is rotated by a stepper motor. The shape of the spiral is such that for uniform stepping movements of the motor the flow through the tube 1 is varied logarithmically.
