Abstract
1301462 Valves LAMBORGHINI OLEODINAMICA SpA 7 Jan 1970 [13 Jan 1969] 727/70 Heading F2V A fluid distributing valve is formed as a single block with a plurality of sections 8, 9, 10, 11 each containing a spool valve slidable in a cylinder to control the flow to and from an hydraulic machine. A first passage 30 equally supplies each section with inlet fluid pressure and a second passage 28, 39, 40 controlled by by each spool interconnects the inlet 6 and outlet 7. Different constructions of spool may be placed in the cylinders and different constructions of check valves may be fitted in apertures 42 so that the machines may be actuated in series, parallel, singly or a combination of these. The check valves Figs. 6 and 7 (not shown) either allow communication between passages 30, 38 and block communication between passages 38, 41 or vice versa and the spool is either conventional Fig. 3 (not shown) or as shown in Fig. 8 wherein return fluid from a machine at port 13, or 14 is passed to the passage 28 of the succeeding valve via check valve 58 or 59 and passages 56, 51, 54 or passages 55, 52, 53.
