| 摘要 |
<p>This invention relates to synchronised hydraulic flow dividing and combining devices which provides flow adjustable calibrated throttles (3) associated with respective branches of the flow path and which provides throttle slides or mobile rings (12, 13) located on the regulating slide valve (4). Each throttle slide (12, 13) is retained on that portion of the regulating slide valve (4) associated with the respective flow path branch and is slidable with respect to the regulating slide valve (4) so as to present respective throttling surfaces (10, 11 or 14, 15) in dependence upon the direction of flow through that flow path branch. Operation of a pilot valve 23 causes inlet fluid to open fully throttle (3) and to act on pistons (17), (16) to lock the regulating slide (4) in its fully open position. <IMAGE></p> |
