Abstract:
1. A fluid pressure control circuit, comprising: a fluid pressure device which is operated by a fluid pressure; a control valve which is connected to the fluid pressure device via a connecting passage, and which changes a flow rate of predetermined fluid that is to be supplied to the fluid pressure device or that is to be discharged from the fluid pressure device according to a position of a valve element; and a pressure difference reflecting device which moves the valve element based on a difference in the fluid pressure between predetermined two different portions in the connecting passage and which changes the flow rate of the fluid that is to be supplied or to be discharged through the control valve according to the fluid pressure difference; wherein the pressure reflecting device includes a first pressure difference detecting passage and a second pressure difference detecting passage, wherein said first pressure difference detecting passage extends from a first location along said connecting passage to the control valve, and wherein said second pressure detecting passage extends from a second location along said connecting passage to said control valve, and further wherein said first and second locations are each located along said connecting passage between the control valve and the fluid pressure device.
