ABSTRACT:
A water brake dynamometer includes a water brake having a stator housing with a rotor disc mounted on a through shaft. Water from a reservoir is directed into the housing as the shaft and rotor are driven by an external engine. Means are provided to measure the torque transferred from the rotor to the stator housing. An adjustable, unitary valve mechanism controls the rate water is directed into the housing from the reservoir and removed from the housing for return to the reservoir. The valve mechanism includes a single stem having multiple valve members operated by a single hydraulic piston control.
