Abstract (en)
[origin: EP3037676A1] 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.
