Abstract

The retarder (2) has a pressure accumulator (3) arranged in a closed loop (7) of a working medium (1) in an area of pressure supply before a retarder regulating valve (4), where the pressure accumulator includes a coil spring. The accumulator is filled with the medium through supply of pressure from the regulating valve via a transmission pump (5), a supply orifice (11) and an integrated aperture.
