Abstract
727,804. Valves. ELECTRAULIC PRESSES, Ltd. Feb. 27, 1953 [March 15, 1952], No. 6762/52. Class 135. A rotary disc valve for distributing pressure liquid to a plurality of valves, each of which controls a separate hydraulic apparatus, comprises a rotary disc 1, Fig. 1, keyed to an operating spindle 4 and enclosed in a three-part valve body 2, 3, 2a. The disc 1 has two concentric rows of axial bores 101 ... 105 and radial bores 11 connecting axial bores on the same radius with an annular space 32 surrounding the disc. On rotation of the disc, an inlet connection E may be brought into communication with outlet connections A, B, C, D, Fig. 2, either individually or jointly to supply pressure liquid in a predetermined sequence to servooperated control valves controlling pumps having capacities in the ratio of 1, 2, 4 and 8 respectively, so that the combined capacity of the pumps may be varied in arithmetical progression from 1 to 15. The arrangement is such that when the axial bore 101 registers with the outlet A, the pump having capacity 1 <SP>"</SP> is loaded, all the others remaining unloaded. Clockwise rotation of the disc brings the axial bore 102 into register with the outlet B to load the pump of capacity 2 and unload the pump of capacity 1. Further clockwise rotation of the disc brings axial bores 103, 104 into register with outlets A and B respectively to give a joint capacity of 3 and so on up to a maximum capacity of 15 when all the outlets are connected to the inlet E. To pressure balance the disc a radial bore 12 and an axial bore 14 connect the space 32 with recesses 13 on either side of the disc, and blind bores 23 are formed in the body part 2 opposite to the outlets A, B, C and D in the body part 2a. A spring-loaded ball 83 engages in notches 19 on the periphery of the disc to locate the disc in each of its positions and a graduated dial 6 co-operates with a pointer on a fixed plate 7 to indicate the pump capacity being supplied.
