ELECTROHYDRAULIC ACTUATION SYSTEM |
摘要 |
An electrohydraulic actuation system in which the quantity of fluid being fed to hydraulic actuators under higher load pressure among those of a plurality of electrohydraulic actuators can be prevented from becoming deficient. In the electrohydraulic actuation system (100), a selection valve (141), a two-position valve (142), a spring (143) and a hydraulic cylinder (144) for altering delivery alter delivery of the working oil of a variable delivery hydraulic pump (111) based on the maximum pressure of the working oil being fed to hydraulic motors (122, 132) and the delivery pressure of working oil of the variable delivery hydraulic pump (111), and pressure gauges (145, 146, 147, 148, 149) and a computer (not shown) alter the rotatim speeds of motors (123, 133) at a substantially same rate for them.
