Marine propulsion engine voltage generator arrangement - Patent 4695261 (3841 words) |
 | The marine propulsion device 10 further comprises conduit means communicating between the water pump 62 and the atmosphere, and a hydraulic fluid or oil cooler 100 communicating with the conduit means to receive cooling water from the water pump 62 and communicating with the pump 64 for cooling the hydraulic fluid pumped thereby. |
| The marine propulsion device 10 further comprises belt means extending around the power takeoff pulley 132 (specifically the sheave portion 135), the drive shaft pulley 92, and the idler pulley 138 for drivingly connecting the power takeoff pulley 132 to the drive shaft pulley 92 for driving the pump 64. |
| The marine propulsion device 10 further comprises means for adjusting the spacing between the idler pulley 138 and one of the power takeoff pulley 132 and the drive shaft pulley 92 so as to adjust the tension on the belt 154. |
| Marine propulsion unit - Patent 4290270 (1843 words) |
| In the construction of propulsion units of the aforementioned type, it has been proposed to operate all of the engines of the propulsion unit along a propeller curve for normal operating conditions, that is, a quiet sea, normal load, and no towing load. |
| When the propulsion unit is operating with all engines the higher propeller speed or r.p.m.'s are attained in the range of higher velocities by increasing the r.p.m.'s of the engines without exceeding their maximum constant output with a corresponding reduction in the amount of fuel injected. |
| Accordingly, it is an object of the present invention to provide a marine propulsion unit which ensures a flawless operation of the unit in the range of medium speeds during a cutting out of a portion of the drive engines of the propulsion unit. |
