  • Combination water pump and belt tensioner
    Patent number: 4822321
    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.
