ABSTRACT:
A pump, driven by the engine, supplies hydraulic pressure as a function of engine speed; the engine controller provides a displacement force, for example by a cam, acting on a main valve slider, or spool of the switching pressure controller. To additionally provide a speed signal to the main spool, the switching pressure line, connected to the pump, has a Venturi, diaphragm, bent tube, or other constriction therein from which a hydraulic signal representative of engine speed can be derived, which hydraulic signal is applied as a force additionally acting on the main valve slider or spool so that the spool position, and hence output switching pressure, will be representative both of engine controller position as well as of engine speed.
