Beschreibung
Zusammenfassung:	A kickdown arrangement for the hydraulic transmission of a motorcar includes an electrohydraulic transducer with a throttle valve operated by an electromagnet, and a control valve controlled by pressure fluid from the throttle valve, and producing a hydraulic kickdown signal when a predetermined maximum control pressure is reached upon full depression of the gas pedal. Both valves receive fluid under pressure from the outlet of a pump driven by the motor which drives the transmission. A servo main valve connects the outlet of the pump with the hydraulic transmission, and is controlled by a control flow from the outlet of the throttle valve.
