Title:
ACCELERATION DEVICE FOR SHIP
Document Type and Number:
Japanese Patent JP3739850
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To adequately adjust oil pressure at every hull, by providing a silencer mechanism at the time of the low speed of an engine, and an acceleration mechanism, for lowering clutch hydraulic pressure to improve acceleration performance; on a hydraulic circuit, to make both the mechanisms changeable, to make oil pressure adjustable at every mechanism.
SOLUTION: A silencer mechanism detects a resonance frequency of a deceleration reverting gear or of an engine, to switch a silencer.acceleration selector valve V8, to flow a pressure oil to a hydraulic fluid tank T via a pressure adjusting valve V9 and silencer restriction 2, and a clutch is slipped, to avoid a resonant frequency region. In an acceleration mechanism, a deceleration reversing gear clutch is separated to join the clutch after an engine rotation frequency is reached to a turbocharger effective rotation frequency region. At this time, an acceleration valve V11 and an acceleration restriction 3 are arranged in series for preventing shock joining, to be joined by the pressure oil via the acceleration restriction 3 having high slip ratio. The mechanism is switched by a selector valve V10, to provide a silencer oil pressure adjusting screw B and an acceleration oil pressure adjusting screw A on the selector valve 8 and the acceleration valve V11 respectively, thereby adjusting pressure separately at the time of switching.
