The invention discloses a compression high-low speed regulating valve device of a vehicle shock absorber, and belongs to the technical field of hydraulic pressure. The high-speed regulating valve comprises an outer valve body, a high-speed valve seat, a high-speed regulating knob, a high-speed knob fixing sleeve, a regulating valve element and a low-speed valve element. The high-speed valve seat is arranged at one end of the outer valve body. The high-speed adjusting knob is tightly attached to the other end of the outer valve body through the high-speed knob fixing sleeve. The adjusting valve element is in threaded connection into the outer valve body, and the low-speed valve element is in threaded connection into the adjusting valve element. A low-speed throttling hole matched with the low-speed valve element is formed in the side wall of the adjusting valve element, a high-speed outer through hole and a high-speed inner through hole are formed in the high-speed valve seat, a one-way valve block is fixed to the end, located outside the valve body, of the high-speed outer through hole through a clamping spring, and a one-way valve block set is arranged at the end, located in the valve body, of the high-speed inner through hole. An adjusting spring is arranged between the one-way valve plate group and the adjusting valve core; a radial through hole is formed in the side wall of the outer valve body. The adjusting speed range of compression damping is wide, meanwhile, the adjusting precision is high, and the excellent operability and comfort of the vehicle can be effectively guaranteed.
