Patent GB-685754-A (GB)
Abstract: 685,754. Fluid-actuated valves. CINCINNATI MILLING MACHINE CO. July 20, 1948 [Aug. 1, 1947], No. 19426/48. Class 135. A control valve pre-settable to select the speed of operation of hydraulic apparatus and automatically adjustable in response to pressure changes in either its supply or its delivery pressure to maintain a constant volumetric flow of liquid and hence the selected speed, comprises a housing 10, Fig. 1, having an inlet bore 11 and an outlet bore 12 and a valve sleeve member 14 having an external groove 25 communicating with the bore 12 and through arcuate grooves 24, Fig. 2, having V-shaped slots 28 with the sleeve interior. The sleeve is also formed with an internal recess 17 connected by radial ports 16 with the bore 11. Within the sleeve is mounted a slidable and rotatable plunger 19 formed with a shoulder 22 co-operating with the recess 17, a recess 20 and arcuate grooves 24 of considerable axial extent co-operating with the slots 28. The plunger 19 is hollowed out at either end, loaded by a spring 54 and an adjustable loading spring 52 and connected by radial ports 49, 50 through the sleeve and plunger respectively with the groove 25 and the recess 20. Lugs 30 formed on the plunger 19 coact with grooves 31 in a rotatable sleeve 32 keyed to a rotatable graduated dial 41 which rotates the plunger 19 to adjust the opening between the arcuate grooves 24 and the slots 28, whilst a screwed plug 53 adjusts the loading on the spring 52. Increased pressure in the bore 12 is communicated through the ports 49 to the righthand end of the plunger to move it to increase the opening between the recess 17 and the shoulder 22 and so restore the pressure differential between the recess 20 and the groove 25, and hence the rate of flow through the slots 28 to their former value. Increased pressure in the bore 11 results in the plunger 19 being moved to the right to decrease the opening between the recess 17 and the shoulder 22 and the restoration of the pressure differential between the recess 20 and the groove 25. Conversely, on a decrease in pressure in either the bore 12 or the bore 11 the plunger 19 will move to maintain the same pressure differential across the slots 28.
