Title: Control device for hydraulically-operated machine
Inventor: TAKAMURA FUJITOSHI
IPC: F15B11/00
Filed: 1993-03-26
Abstract: PURPOSE:To improve operation property of a hydraulically-operated machine by detecting motor speed and hydraulic pump delivery pressure or actuator load pressure of a plural number of operation machines and operating quantity of a plural number of flow control valves, setting absorption torque of a hydraulic pump based on target motor speed and vary a differential pressure set value in accordance with the detected values and the set values. CONSTITUTION:Number of revolutions of an engine 1 and delivery pressure of a hydraulic pump 2, in other words, load pressure of operation machine actuators 3, 4 and respective operation quantities of operating valves 7, 8 are detected, absorption torque of the hydraulic pump 2 is set in accordance with equi-horsepower control based on the target number of revolutions of the engine 1 and the detected number of revolutions and differential pressure is varied in accordance with the respective detected values and the torque set values. Thus, because the larger the load gets the smaller the differential pressure gets, a dead band proceeds to a characteristic of a small inclination without proceeding to a characteristic of a wide dead band even if the load becomes high and a good operation property is maintained with the dead band kept small. Furthermore, equi-horsepower control of absorption torque of the hydraulic pump 2 is also performed so engine stall may not take place.

Abstract: PURPOSE: To protect a signal pressure control valve for regulating the signal pressure to an exhaust gas recirculating (EGR) control valve against corrosion with condensed exhaust gas water.  
     CONSTITUTION: There are provided a conduit 31 for introducing exhauat gas pressure from a passage 12, and a semiconductor pressure sensor 32 incorporating two gauges 32a, 32b varying their electric resistances in response to the pressure and connected to the end of the conduit 31. The first gauge 32a increases its resistance R when the pressure P in the passage 12 is increased, and the second gauge 32b gradually increases its resistance R as the pressure P is increased to thus cause the potential difference therebetween to increase as the pressure P is increased. This potential difference is amplified by an amplifying circuit 41, and a comparator compares the output voltage V 1  from the circuit 41 with a set voltage V 2  produced from a set voltage circuit 42. When the pressure P in the passage 12 is increased to become V 1  > V 2 , a solenoid valve 50 is deenergized to thereby introduce the suction vacuum into the diaphragm chamber 16 of an exhaust gas recirculation (EGR) valve 10 to thereby open the EGR passage 23 via a valve body 13.
