Filed: 1995-04-17
Abstract: PURPOSE: To improve accuracy for controlling a hydraulic oil flow rate performed by a flow rate control valve by rectifying a relational expression between an input instruction current value and the duty ratio of an output duty signal based on a duty signal fetched from an operating means. CONSTITUTION: When an operation lever 5 is operated from a neutral position N to an up position U side, a control valve 3 is operated from a neutral position 3N to an expansion position 3U by an operation unit 7 based on an instruction current I. Simultaneously, a duty signal D is outputted from operation oil 7 and a flow rate control valve 4 is continuously operated alternately between an open position 4a and a closed position 4b. Hydraulic oil is supplied from a pump to a hydraulic cylinder 1 via the control valve 3 and the hydraulic cylinder 1 is expanded, raising a boom. A relational expression between the value of the input instruction current I and a duty ratio D is corrected so as to coincide with an actual condition when necessary. Thus, accuracy for controlling a hydraulic oil flow rate by the flow rate control valve 4 is improved.

Title: Direct acting type electromagnetic valve and liquid pressure device using same
Inventor: SUHARA MASAAKI
IPC: F15B9/09
Filed: 1989-04-10
Abstract: PURPOSE:To improve controllability by dividing a communication hole into a plurality of groups in a direct acting type electromagnetic valve for adjusting the opening area of a throttle passage between ports, displacing the location of each group in a spool shift direction and arranging the communication holes of each group in such a way as to keep the balance of a radial load due to the passage of a fluid. CONSTITUTION:A primary port P and a secondary port B becomes continuous to each other only via the constitutional holes 3a to 3d of one group 3 among a plurality of groups, due to the shift of a spool 5. In this case, as the opening area of a throttle passage 6 is smaller than all communication holes 1 to 3, an increase in a flowrate to the port B can be restrained to a low level and controllability can be alleviated due to a drop in sensing the flowrate. When instruction input is high and the shift of the spool 5 is large, the constitutional holes 2a to 2d and 1a to 1d of groups 2 and 1 open one after another, thereby reducing a pressure loss. Furthermore, the constitutional holes of groups 1 to 3 are so positioned as to keep the balance of a radial load due to the blow reaction of the fluid, stable control can always be done. According to the electromagnetic valve constructed as aforementioned, the control of an actuator can be properly done.
