Abstract
A marine installation comprising a valve and cylinder apparatus including a housing having therein a spool bore extending along an axis, a second bore extending along a second axis parallel to and spaced from the spool bore axis, and a cylinder bore extending along an axis parallel to the spool bore axis, a spool slidably housed within the spool bore, a tubular member slidably housed within the second bore, and a link for moving the spool along the spool bore axis in response to movement of the tubular member along the second axis, a piston slidably housed within the cylinder bore, a piston rod having a first end fixedly connected to the piston, and a second end connected to the propulsion unit for causing pivotal movement of the propulsion unit about its steering axis in response to axial movement of the piston rod, and a cable assembly including a sheath fixedly connected to the tubular member for movement therewith, and an inner core extending through the tubular member and fixedly connected to the second end of the piston rod for movement therewith.
