Compound remote control device for the propulsion engine of a ship's
variable-pitch propeller
Abstract:
The present invention relates to a compound remote control device for controlling the pitch of a variable-pitch propeller on a ship's drive mechanism while at the same time controlling the speed of the ship's engine, and provides a control mechanism for compound control under various control conditions, whereby the conventional equipment being of a complex structure using 2 cams, is simplified by using one cam and a pressure-control valve cooperating therewith. With said control device, control of the speed of the aforesaid engine and the control of the pitch of the variable-pitch propeller are carried out by using air-pressure signals under various control conditions, that is, where the relationship of the various control air pressures in relation to the position of the control lever varies as for example shown in FIG. 1.
