The invention discloses an exhaust valve, a compressor and a pump driving loop heat pipe. The exhaust valve comprises a valve disc, a limiting plate, a connecting piece, a supporting piece or a valveplate and the like, wherein the valve plate is provided with an exhaust hole with the aperture or equivalent aperture of d, the valve plate is further provided with a connecting piece mounting hole, the distance between the exhaust hole and the mounting hole is L, the valve disc is an elastic flat plate with a thickness of delta, the mounting ends of the valve disc and the limiting plate are provided with through holes through which the connecting piece passes, the portion, near the through hole, of the limiting plate is flat, and the other end of the limiting plate warps upwards. During assembly, the end, without the through hole, of the valve disc covers the exhaust hole, the other end of the valve disc is pressed on the mounting hole in the valve plate by the limiting plate, and the valve disc, the limiting plate and the valve plate are assembled into a whole through the connecting piece. The relation between delta and d of the exhaust valve meets the relation that delta divided byd is less than 0.025 and equal to or greater than 0.010, and the relation between delta and L meets the relation that delta divided by L is greater than 70 and equal to or less than 150. The operatingenergy efficiency ratio and reliability of the compressor adopting the exhaust valve can be effectively improved, and exhaust noise can be obviously lowered.
