ABSTRACT:
To independently supply pressurized fluid from a fluid pump to first and second hydraulically powered devices to be operated independently under different conditions, a flow-divider valve comprises a valve body assembled within a casing to form a first pressure chamber in open communication with the fluid pump and a second pressure chamber in open communication with the first hydraulically powered device, the first pressure chamber being selectively connected with the second hydraulically powered device in response to displacements of the valve body to regulate fluid quantity to be supplied into the second device and the communication degree between the second pressure chamber and the first device being regulated in response to the displacements of the valve body. The flow-divider valve further comprises a variable orifice assembled within the casing between the first and second pressure chambers to regulate fluid flow from the pump toward the second pressure chamber, and means for controlling the throttling degree of the orifice in response to pressures independently exerted within the first and second hydraulically powered devices.
