Title: Low speed return
Inventor: MALONE JOHNATHAN E
IPC: F16H61/4192
Filed: 2000-11-07
Abstract: PURPOSE: A vehicle speed control system is provided in which an operator changes a switch position before high speed operation after start up, regardless of the position of the speed selection switch on start up. CONSTITUTION: A speed selection switch(20) comprises a first or low speed position wherein output terminal(48) connected to the line to the control input(26) is open so no power is applied to the speed control valve(16) and the low speed range of operation is provided. In the first position, a second output terminal(50) is connected through the switch to the line(31) to provide a closed path between the switched power line(24) and the control input(42) of the relay(22). Therefore, when the line is powered and the switch is in the low speed position , the relay activates to provide a closed path between the terminals(32,34) and connect the line with the control input so the relay is bootstrapped into the on condition as long as the line is powered. However, since the path to the control input is open when the switch in the low speed position shown, the speed control valve(16) is deactivated and the low speed range is established by the valve. To establish high speed operation, the operator moves the switch down from the position to establish a closed circuit from the control input to the powered line via terminals(48,30) of the switch and terminals of the relay.
