Title:
減速逆転機
Document Type and Number:
Japanese Patent JP7369438
Kind Code:
B2
Abstract:
To provide a reduction reverser preventing a failure leading to damage or seizure by having a normal/reversal mechanism be in a slip engagement state by attempting to immediately switch to a power cut-off state when an action detection member makes a detection error of being in a neutral position regardless of the normal/reversal switching valve being in a position other than a neutral position in normal navigation.SOLUTION: A reduction reverser 9 including a normal/reversal switching mechanism 17 for transmitting rotational power of a main engine 7 loaded on a hull to a propeller 5 by switching output of normal rotation, neutral, or reversal rotation, a normal/reversal switching valve for controlling switching action of the normal/reversal mechanism, and a trolling machine for adjusting hydraulic fluid pressure toward the normal/reversal mechanism is composed to include an action detection member for detecting an action state of the normal/reversal switching valve and to have the trolling machine not reduce the hydraulic fluid pressure going toward the normal/reversal mechanism when the action detection member detects that the normal/reversal switching valve is in the neutral position during normal navigation.SELECTED DRAWING: Figure 2
