Hydrodynamischer Retarder

摘要

The retarder (1) for a goods vehicle, has a rotor (2) with buckets arranged around its periphery. The rotor (2) rotates inside a housing (3) with a fixed ring of buckets. The rotor (2) is connected to the propeller shaft of the vehicle and the retarder is brought into operation by circulating a liq. through the housing (3). The liq. flowing out of the housing flows through a pipe (6) which is connected to two parallel pipes (10,11) with different cross-sectional areas. The liq. flowing in each pipe is separately cooled in a heat exchanger (15). The smaller dia. pipe (11) is fitted with a 2/2 ways slide valve and a non-return valve (32) is fitted in the larger dia. pipe (10).
