Abstract
An improved tilt piston stroke control arrangement that employs a stroke control valve that controls the tilt stroke by closing a hydraulic conduit at a predetermined stroke position to thus shutting off the feed of hydraulic pressure to the tilt cylinder. Thus, the stroke control valve can be provided in any position in the associated hydraulic circuit. This increases the degree of freedom for layout and makes it possible to achieve a compact layout.
Claims10
A tilt cylinder device for tilting an outboard drive between an underwater, driving position and an out of the water storage position comprising a cylinder assembly defining a cylinder bore, a piston reciprocating in said cylinder bore and dividing it into two fluid chambers, a piston rod affixed to said piston and extending through one of said fluid chambers and terminating externally of said cylinder assembly, said piston rod and said cylinder assembly each being pivotally connected to a respective one of an outboard drive and a watercraft for effecting the tilting of the outboard drive, a hydraulic circuit for controlling the operation of said tilt cylinder device and a tilt range control valve for disabling the operation of said hydraulic circuit for selectively limiting the stroke of said piston.
