Title:
REMOTE CONTROLLER OF ENGINE
Document Type and Number:
WIPO Patent Application WO/1990/001630
Kind Code:
A1
Abstract:
This invention relates to a remote controller which outputs an electrical operation signal from an operation device (10) to the driving device (6) of a governor mechanism (2) of an engine (1) to remote-control the governor mechanism (2). This remote controller includes a detection device (8) for detecting a control quantity of the governor mechanism (2) and a control device (13) to which an operation signal from the operation device (10) and a detection signal from the detection device (8) are inputted. When the difference between a control quantity at a certain time and a control quantity detected a predetermined prior to that time is below a predetermined value, this control device (13) judges this state as an operation limit of the governor mechanism (2) and outputs a stop signal to the driving device (6). In this manner, damage to the governor mechanism (2) and the driving device (6) is prevented.
