摘要： A hydraulic control apparatus (1) includes a switch valve (11) , a valve support chamber (35) , a flow control valve (12) movable therein, an on-off valve (13) movable within a communication path chamber (12a) located inside the flow control valve (12)', and a valve control device 14. The on-off valve (13) can open and shut off a communication path X between a cylinder line (32) and a switch valve line (33). A restrictor formed between the flow control valve (12) and a wall defining the valve support chamber (35) connects the cylinder line (32) and the communication path chamber (12a). The restrictor opening is changed in correspondence with movement of the flow control valve (12). When the switch valve (11) is located at the drainage position, the valve control device (14) applies a pilot pressure lower than the pressure in the cylinder line (32) to a back pressure chamber (12d) of the flow control valve (12) , thereby moving the on-off valve (13) in a direction for opening the communication path X.

摘要： An electromagnetic proportional flow rate control valve capable of performing precise flow rate control in a low flow rate side of an operating region is provided. In an electromagnetic proportional flow rate control valve 32, in which a valve member 2 is driven in a valve closing direction in accordance with the increase in a driving current I of a solenoid coil 15, a solenoid driving force F is set such that it decreases accompanying the displacement of the valve member 2 in the valve closing direction with respect to an identical driving current in the solenoid coil 15. Thus, an amount of change in an area of a valve opening with respect to unit changes in the driving current I becomes smaller in a region at which the stroke is small compared to a case of having flat characteristics, whereby the flow rate control precision in the low flow rate region can be improved.

摘要： An independent metering valve (IMV) assembly is disclosed that includes a metering stem including an inlet. The IMV assembly also includes a hydro-mechanical control valve in communication with a fluid source and the inlet. The control valve also including a spool with a closed end and an open end. The control valve includes a biasing member that biases the control valve or spool towards an open position thereby establishing communication between the fluid source and the inlet. The control valve also including a load signal line providing communication between an outlet of the control valve upstream of the inlet and the closed end of the spool. Wherein high pressure in the load signal line allowing the control valve to move towards a closed position thereby overcoming bias of the biasing member and reducing flow to the inlet during a high pressure condition.

摘要： A flotation control system for controlling the boom of a tractor or brush cutting machine. Three hydraulic valves operate together and work in conjunction with the existing main valve of the tractor or brush cutting machine to provide flotation control or automatic movement up and down of the boom in response to ground surface variations. The system also allows the amount of weight that the cutter or other attachment exerts against the ground to be increased or decreased. The first valve is a flow control valve or a flow restricting or dividing valve that divides hydraulic flow from the pump of the tractor to the flotation control system. The second valve is a pressure reducing valve that provides the general operation of the flotation control system. The third valve is a directional valve and functions as an on/off for the flotation control system. The third valve allows a float mode by moving a cylinder which is already present in the tractor hydraulic system up or down to control movement of the boom up or down. The system is used in either a closed center or open center hydraulic system. A method of providing flotation control for controlling the boom of a tractor or brush cutting machine is also disclosed.
