Title:
POWERED-TILT DEVICE FOR OUT DRIVE UNIT
Document Type and Number:
Japanese Patent JPS63180591
Kind Code:
A
Abstract:
PURPOSE:To simplify operation and to effect operation speedy, by providing a control device for permitting tilt up and down operation of an out drive unit only by depressing a push button. CONSTITUTION:When a power cylinder is tilted up, a push button switch P1 is depressed to cause a hydraulic pump 47 to supply pressurized oil to an oil chamber 24 on the up side of the power cylinder from an oil basin 45 through a check valve 49. When it is tilted down, a push button P2 is depressed to discharge pressurized oil in the oil chamber 24 on the up side of the power cylinder 22 through a change-over valve 54. On the other hand, check valves 52, 61 which are opened and closed in the opposite directions each other are disposed in parallel to an oil chamber 25 on the down side, so that pressurized oil is supplied to and discharged from the oil basin 45 in association with the flow of the pressurized oil into and out of the oil chamber 24 on the up side. In addition, the hydraulic pump 47 or the electromagnetic change-over valve 54 are turned off in response to signals sensed by limit switches 65, 66 for sensing the completion of up or down of the out drive unit 1.
