Abstract

552,586. Dynamometers. BROWN & SONS (HUDDERSFIELD), Ltd., D., and MERRITT, H. E. Oct. 15, 1941, No. 13261. [Class 106 (ii)] A dynamometer comprises a fluid pump the casing of which is mounted pivotally so that the torque exerted upon it may be measured, characterised in that the pump consists of a central toothed driving rotor engaging with two toothed driven rotors disposed on diametrically opposite sides of the said driving rotor. A central toothed driving rotor a drives two rotors c, d, preferably of smaller diameter, rotor a preferably having an odd number of teeth to make the discharge more uniform. The casing e is journalled on bearings coaxial with the shaft of rotor a, and is secured to torque-measuring means comprising a spring balance c and a dashpot w. The two pressure cavities f and the two suction cavities g are connected by passages in the casing or end walls to opposite sides of piston valve k, housed in a separate unit bolted to the casing. The stem of the valve is connected by an adjustable link to a fixed point. Fluid is drawn from a supply pipe s and is discharged through a small pipe t. Instead of a fixed anchorage, the valve may be connected to a governor or to a differential gear and synchronous motor, so as to keep constant the speed of the engine being tested.
