发明名称	Hydraulic control circuit for synchronising two hydromachines - has by=pass valves in parallel with machines, enables machine of equal displacement to be used
摘要	The hydraulic control circuit for sync. two hydromachines (20,30) connected in series contains pulsed speed sensing arrangements for each machine. One machine has a bypass adjusted according to the difference in sensor signals. Both hydromachines have the same displacement. One bypass can be a proportional distributing valve (26) connected in parallel with the corresp. machine and the bypass for the other machine is then a flow valve (36) connected in parallel. USE/ADVANTAGE - The circuit eliminates the conventional limitation of only being able to use machines with different displacements.
