The invention relates to an undercarriage buffer which can exert a good buffering function in take-off, landing and sliding processes of an airplane. The undercarriage buffer comprises an outer cylinder 1, a fuel injection inflation valve 2, an inner cylinder 3, a fuel needle 4, a damping device 5 and a supporting ring 6, wherein the damping device 5 comprises a supporting piece 14, a connecting piece 15, a valve 16, a throttling valve 17, a return spring 18, a locking washer 19 and a piston ring 20, wherein the connecting piece 15 is fixed on the fuel needle 4 by threads at the upper part of the connecting piece 15; the throttling valve 17 is connectedwith the lower end of the connecting piece 15 by the threads; the supporting piece 14 is fixed at the lower end of the fuel needle 4; the locking washer 19 is used for the fixing between the supporting piece 14 and the connecting piece 15; the return spring 18 is mounted between the supporting piece 14 and the valve 16, and used for the return of the valve 16; four small holes are formed in the connecting piece 15 and act as damping holes during a forward stroke of the buffer; and four small holes are formed in the throttling valve 17, and act as damping holes during a reversal stroke of the buffer.
