Title: Throttle position regulator - compares accelerates pedal position with throttle valve position electronically to hydraulically adjust throttle valve
Inventor: LEIBER HEINZ ING GRAD
IPC: F02D9/02
Filed: 1974-08-01
Abstract: The accelerator pedal is coupled to a transmitter which produces an electrical signal corresponding to the pedal position. The signal is fed to a comparator along with a second signal from a throttle position dependant transmitter. Should the accelerator dependent signal be greater than the throttle valve signal, the comparator passes a corresponding signal to an electro magnetic three way valve which, in its non excited position makes a connection between the hydraulic return flow from the throttle slave cylinder to the fluid tank and in its excited position connects the cylinder with the fluid delivery pump. Should the throttle valve position dependent signal be greater or equal to the accelerator position signal, no signal is passed to the magnetic valve.
