The present invention relates to a feeding control device for a fluid retarder, which is installed in a fluid retarder to improve a braking force by performing a role of an auxiliary brake by being connected to a driving shaft of a vehicle and generating deceleration torque. The feeding control device for a fluid retarder includes: a housing having a first inlet connecting the inside and the outside, a first outlet, a second inlet, and a second outlet, wherein the inside of the housing is hollow; a body connected to the housing to rotate and having a spiral flow path on the outer circumference, wherein the outer circumference of the body is attached to the inside of the housing; and a flow path opening and closing device opening and closing the second inlet or the second outlet formed in the housing. The first inlet is connected to the second outlet through the spiral flow path in accordance with an angle in which the body rotates, or the first inlet is connected to the first outlet and the second outlet through the spiral flow path, or the first inlet is connected to the first outlet through the spiral flow path. The second inlet and the second outlet are connected or blocked in accordance with the operation of the flow path opening and closing device. So, the feeding control device for a fluid retarder is installed in the retarder to supply a working fluid to an operating chamber in the retarder or to discharge the working fluid. The feeding control device for a fluid retarder can accurately control a charging rate of the working fluid filled in the retarder. |
