摘要： An actuator unit includes two chambers defined in the cylinder; a supply passage allowing a working fluid discharged from the pump to be supplied to the two chambers; a discharge passage allowing the two chambers to communicate with the tank; a direction control valve configured to selectively communicate each of the two chambers with one of the pump and the tank; a control passage that branches from the supply passage on a side of the pump rather than the direction control valve so as to communicate the pump with the tank; a variable relief valve provided on the control passage, the variable relief valve opening so as to allow the working fluid to flow from the supply passage toward the tank when a pressure in the supply passage reaches the valve opening pressure; and a center passage that communicates the tank with an interior of the cylinder.

摘要： The energy efficiency is increased by reducing the throttle/relief loss in the delivery flow of the hydraulic pump caused by the bleed-off control, while also making it possible to control the delivery pressure of the hydraulic pump according to the operation amount of the control lever unit and improving the operational performance. A controller 6 includes a target pump pressure setting unit 32 which calculates a target pump delivery pressure which increases with the increase in an operation amount signal from an operation amount detector 20A/20B based on the operation amount signal and a pump flow rate upper limit setting unit 33 which calculates a pump flow rate upper limit which increases with the increase in the operation amount signal based on the operation amount signal. The tilt amount of the hydraulic pump 2 is controlled based on the target pump delivery pressure calculated by the target pump pressure setting unit 32, the pump flow rate upper limit calculated by the pump flow rate upper limit setting unit 33, and the delivery pressure of the hydraulic pump 2 detected by a pressure detector 21.

摘要： The object of the present invention is to provide a multiple direction switching valve capable of stopping acceleration of a first actuator upon operation of a second actuator, without adding any outside pipe. A boom accelerating valve 4 is located in a valve member block 10, the boom accelerating valve 4 having an accelerating position 4a at which pressure oil from a second pump 52 is supplied to a boom hydraulic cylinder 55, and a neutral position 4b at which the pressure oil from the second pump 52 is not supplied to the boom hydraulic cylinder 55. In addition, a boom acceleration releasing mechanism is provided in the valve member block 10, the boom acceleration releasing mechanism being configured to return the boom accelerating valve 4 to the neutral position 4b from the accelerating position 4a, when an arm direction switching valve 2z is operated.

摘要： To cope with a variety of flow rate balance required of two actuators flexibly in combined operations driving two actuators of high maximum demanded flow rates at the same time while suppressing the wasteful energy consumption caused by the throttle pressure loss in a pressure compensating valve, the arrangement is such that when the demanded flow rate of a boom cylinder 3a is lower than a prescribed flow rate, the boom cylinder 3a is driven only by hydraulic fluid delivered from a single flow type main pump 202 and when the demanded flow rate of the boom cylinder 3a is higher than the prescribed flow rate, the hydraulic fluid delivered from the single flow type main pump 202 and hydraulic fluid delivered from a first delivery port 102a of a split flow type main pump 102 are merged together and the boom cylinder 3a is driven by the merged fluids. Further, when the demanded flow rate of an arm cylinder 3b is lower than a prescribed flow rate, the arm cylinder 3b is driven only by hydraulic fluid delivered from a second delivery port 102b of the split flow type main pump 102 and when the demanded flow rate of the arm cylinder 3b is higher than the prescribed flow rate, hydraulic fluid delivered from the first delivery port 102a and hydraulic fluid delivered from the second delivery port 102b are merged together and the arm cylinder 3b is driven by the merged fluids.
