| 摘要 |
A dynamic balancer for a prime mover, such as an internal combustion engine, with at least one balance shaft driven by the crankshaft of the engine, includes a pressure generator on the at least one balance shaft. The pressure generator creates an output signal of pressurized working fluid whose pressure is speed-related. In one embodiment, the speed related pressure signal is applied to a device outside the balancer via a suitable passage. In other embodiments of the invention, a working fluid pump is also driven by at least one of the balance shafts of the dynamic balancer and the speed-related pressure signal is applied to the working fluid pump to control its output.
