[0022] The following describes a bidirectional relief valve for a hydraulic motor according to an embodiment of the present invention with reference to the accompanying drawings.

[0023] like Figures 1-4 As shown, the bidirectional relief valve for a hydraulic motor according to this utility model embodiment includes: a valve body 1 and three sets of fixing mechanisms 5.

[0024] Among them, the three sets of fixing mechanisms 5 are respectively installed on the side wall of the valve body 1.

[0025] The fixing mechanism 5 includes two fixing rings 51, two storage columns 52, two springs 53, two connecting columns 54, and two fixing plates 55.
