  • Hydraulic control device for a work machine
    Patent number: 5329441
    Abstract: A control device for hydraulic equipment where an oil pressure sensor provides an oil pressure output. The sensed pressure output is used in a table to derive a controlled variable limit which is then compared with a controlled variable input. The smaller of the input and limit are used to control hydraulic pressure supplied to the hydraulic oil line. However, also included is a correction device which adjusts the table depending upon whether the output is at a desired oil pressure value or not.
