ABSTRACT:
A clutch element for a unit is driven via a drive shaft, especially for a water pump. The clutch element comprises a temperature- and/or speed-sensitive clutch member which is rigidly connected with the drive shaft and which acts on a part of the unit to be driven depending on the temperature and/or rotational speed, with the clutch member being formed by a clutch disk whose surface forms at least one clutch surface for non-positive connection with a respective counter-surface which is formed by a surface of the part to be driven. At least one clutch surface comprises at least one drainage groove.
