The invention relates to a retarder, in particular to an intensive retarder, and aims to solve the problems that an existing retarder is large in number of accessory parts, not beneficial to daily maintenance and repair work, high in station maintenance cost, large in pollution discharge capacity in the machining process and prone to polluting the environment, and when the retarder is scrapped, metal resource waste of the accessory parts is serious. The hydraulic retarder comprises a shell, a sliding oil cylinder, a piston rod, a speed valve seat, a speed valve plate, a speed valve spring, a dustproof ring, a piston, a pressure valve plate, a pressure valve outer spring, a return valve plate, a slow return valve plate bracket, a pressure valve inner spring, a sealing cover and a cotter pin. The sealing cover is installed at the bottom end of the sliding oil cylinder, the piston rod is inserted into the sealing cover, the speed valve seat, the piston, the pressure valve plate and the slow return valve plate bracket are arranged on the piston rod in a sleeving mode from top to bottom, and the slow return valve plate bracket is sleeved with the return valve plate. The hydraulic retarder is suitable for a speed regulation device used for railway vehicle humping.
