an elastic means 6 for holding the stopper ball 4 between the second port 8 and the first port 7 or the third port 9.
Specifically, when the plug ball 4 is positioned between the first port 7 and the second port 8, the second port 8 and the first port 7 are blocked, and the second port 8 is communicated with the third port 9; when the plug ball 4 is positioned between the third port 9 and the second port 8, the second port 8 and the third port 9 are blocked, and the second port 8 is communicated with the first port 7; when the elastic mechanism 6 provides pretightening force to enable the plug ball 4 to block any one of the second port 8 and the first port 7 or the third port 9 at the initial position, the first port 7 or the third port 9 can be optionally used for feeding oil when the forward oil delivery is realized, and the second port 8 can be used for discharging oil; when the oil is reversely conveyed, the second port 8 is filled with oil, and the starting position in the first port 7 or the third port 9 is not blocked, so that the situation that the oil is discharged from the first port 7 or the third port 9 can not be confirmed when the second port 8 is filled with oil is avoided.
Further, one of the oil inlets is selected as an oil inlet by the elastic mechanism 6 in cooperation with the input oil pressure of the first port 7 and the third port 9.
In this embodiment, the lumen comprises:
the middle section, the stopper ball 4 is arranged in the middle section, and two ends of the middle section are provided with closing-in ports 5 matched with the periphery of the stopper ball 4;
the two side sections are respectively arranged at the two ends of the middle section through the closing-in 5.
Specifically, the second port 8 is sealed off from either the first port 7 or the third port 9 by the line between the closing-in port 5 and the stopper ball 4, thereby preventing the communication between the first port 7 and the third port 9.
In this embodiment, the first opening 7 and the third opening 9 are respectively disposed on two side sections, and the elastic mechanism 6 is disposed in any side section for attaching the stopper ball 4 to any of the closing-in openings 5.
In this embodiment, the closing-in 5 is in a shape of a truncated cone, and the outer periphery of the plug 4 and the closing-in 5 form a sealing line.

the third port 9 and the first port 7 are simultaneously fed with oil;
when the pressure of the third port 9 and the pretightening force of the elastic mechanism 6 are not smaller than the pressure of the first port 7, oil enters the valve cavity 3 through the third port 9 and then flows out through the second port 8;
when the pressure of the third port 9 and the pretightening force of the elastic mechanism 6 are smaller than the pressure of the first port 7, the oil pushes away the plug ball 4, the oil enters the valve cavity 3 through the first port 7 to push the plug ball 4 to be attached to the closing-in 5 close to the third port 9, and meanwhile, the oil flows out through the second port 8;
when oil enters from the second port 8, the plug ball 4 resets to block the second port 8 and the first port 7, and the oil flows out from the third port 9, so that the situation that the position of the plug ball 4 cannot be confirmed and whether the oil is discharged from the third port 9 or the first port 7 cannot be judged is avoided.
