Title: Dynamometers
IPC: G01L3/20
Filed: 1981-06-19
Abstract: A dynamometer for testing internal combustion engines has an input coupling 112 rotatable about an axis 126 and arranged for connection tot e engine to be tested. An hydraulic pump 109 is driven from the input coupling and is fixed to a manifold 114 connected via a load cell to the dynamometer frame 101. A fixed manifold 125 is mounted on the frame 101 and is connected to the pump manifold 114 by conduits 122, 123, 124. The conduits are pivoted to the pump manifold 114 at the axis 126, which intersects the respective conduit axes. Thus, the forces resulting from the fluid under pressure in the conduits and in the pump manifold act through the input coupling axis 126 and do not exert any turning moment about this axis. Accordingly, the forces result from the fluid pressure do not affect the measurement of the load applied by the engine being tested, so that the accuracy of the dynamometer is greatly improved. <IMAGE>
