摘要： The control valve apparatus holds a seat valve member in a position seated on a valve seat to thereby prevent a backward flow even if the pressure in the inlet chamber side becomes lower than the pressure in the outlet chamber side. With a pilot control valve member is in a closed state, when the pressure in the inlet chamber is higher, a pressurized medium is introduced to the control pressure chamber via a first valve unit and is cut off from the outlet chamber by a second valve unit. When the pressure in the outlet chamber is higher, the pressurized medium is introduced to the control pressure chamber via the second valve unit and is cut off from the outlet chamber by the first valve unit.

摘要： A hydraulic drive system has directional flow control valves (10a-f) for selectively supplying a hydraulic fluid, inflow control valves (201-203) disposed respectively in branch lines (150A-C) branched from a supply line (100) for supplying a hydraulic fluid to rod pushing-side chambers (5aA, 5bA, 6A, 7A) of hydraulic cylinders. A bypass flow control valve (204) is disposed in a line (104) connecting the supply line (100) and a reservoir (2). A controller (31) is provided for computing control variables corresponding to operation command signals from control levers (32, 33) and controlling the inflow control valves (201-203) and the bypass flow control valve (204) in accordance with the computed control variables. As a result, the number of flow control valves and the length of piping required for connection of the flow control valves can be further cut, and a total pressure loss can be further reduced. A reduction in the number of flow control valves contributes to simplifying layouts of hydraulic piping between hydraulic sources and actuators receiving hydraulic fluids from the hydraulic sources.

摘要： This invention relates to a fault diagnosis system for hydraulic pumps in a work vehicle, which is economical and permits sure identification of one or more trouble-developed ones of the hydraulic pumps.Pressure sensors 61-64 are arranged on pressurized fluid lines 30,40, which extend to a tank T from points immediately out of center bypasses of flow control valves 21,231-234,451-454,26 communicated to hydraulic pumps 1-6. Solenoid-operated directional control valves 51-56 are interposed in input circuits of individual regulators 11-16 so that, upon excitation, a pressure of a pilot pump 7 is introduced into the regulators 11-16. When all the flow control valves are brought into neutral positions thereof and a determination is instructed through a switch 80, one of the solenoid-operated directional control valves is excited by a signal from a processor 70 so that pressurized fluid is delivered at a maximum flow rate from the corresponding hydraulic pump. A detection value of the corresponding pressure sensor at this time is translated into a flow rate, which is then stored. These procedures are performed with respect to the individual hydraulic pumps successively. Based on a flow rate obtained in every determination, a fault diagnosis of the corresponding particular hydraulic pump is performed.

摘要： This invention relates to a measuring and display system for loads applied upon digging blasted earth, which can contribute to accurate blasting. An operating direction of a bucket of an excavator is detected by pressure switches 15,16, while a pressure P.sub.B in a bottom compartment 6S.sub.B of a bucket cylinder is detected by a pressure sensor 17. A processor 23 computes a digging position based on signals from a boom angle sensor 18, an arm angle sensor 19, GPS 20 and a magnetic direction sensor 21, integrates pressures P.sub.B during an ON period of the pressure switch 15, and transmits the thus-integrated pressure together with the digging position to a computer 30. The computer 30 displays a map of a lot under blasting and blasting positions on a display, and on the map, also displays the thus-transmitted digging position by a mark X and the integrated pressure by a numeral. With reference to this integrated pressure, a determination is made as to whether the blasting was proper or improper. The results of this determination are used for the next blasting.

摘要： A system for the estimation of residual service time of a work vehicle includes an arithmetic and logic unit which is inputted with an engine speed and a speed difference from a controller for an engine, with a signal, which indicates whether or not at least one of several control levers has been operated, from a lever position detector, and also with a residual fuel quantity in a fuel tank from a converting device. The residual fuel quantity is determined at intervals of about 1 hour at the arithmetic and logic unit. Upon an elapse of each short period of time, a quantity of fuel consumed during said short time, said quantity being obtained based on a difference in engine speed, is subtracted from the residual fuel quantity, whereby a calculated residual fuel quantity is obtained. A quantity of fuel consumed from a preceding residual fuel quantity measurement period to a current residual fuel quantity measurement period is divided by the calculated residual fuel quantity to obtain a value. The residual fuel quantity is then divided by this value to compute a residual service time, which is then displayed on a display.
