Abstract
A combined water pump and belt tensioner includes an arm pivoted to the outside
of the water pump housing so as to swing about the axis of the pump shaft. Loads on the arm are
transmitted to the pump housing, but not to the pump shaft. A pulley on the arm both tensions the
belt and powers the pump shaft through a small drive belt that compensates for the swinging of the arm.
