Abstract
Control for a continuously adjustable drive, equipped with a signal transmitter arbitrarily actuatable by a manipulation element, in which the conversion setting imposed on the drive is influenced by the position of the manipulation element, in which case an additional r.p.m.-dependent signal is superimposed on the signal emitted by the signal transmitter, at least at excessively small drive r.p.m.'s, where the arbitrarily adjustable signal transmitter preferably is a pressure-regulating valve to which the pressure impounded in front of a restrictor in the delivery line of a constant pump is fed.
