Flow rate changing arrangement for positive displacement machine, has swiveling angle regulating device including adjusting valve and adjustment modes, where selection of active modes takes place through rate of electrical control signals

摘要

The arrangement (A) has a swiveling angle regulating device including an electrically controlled delivery volume adjusting valve (FSV) and a pair of adjustment modes. One of the adjustment modes is realized by the swiveling angle regulating device with a mechanical breakout of a swiveling angle on the valve, and the other mode is realized by a regulator circuit with an electronic breakout of a controlled variable of a positive displacement machine on an adjustment signal of the valve, where the selection of active modes takes place through rate of electrical control signals.
