Patent ID: 8840438

Claim:
An assembly of hydraulic systems comprising: a hydraulic system for operating at least one first system used in the operation of a watercraft; at least one other hydraulic system for operating at least one second system used in the operation of the watercraft, the at least one other hydraulic system comprising: a first driving hydraulic actuator for directing fluid flow within the at least one other hydraulic system; and at least one first driven hydraulic actuator for operation of the at least one second system used in the operation of the watercraft; the hydraulic system comprising: a reservoir; a second driving hydraulic actuator fluidly connected to the reservoir for directing fluid flow within the hydraulic system; and at least one second driven hydraulic actuator fluidly connected to the second driving hydraulic actuator for operation of the at least one first system used in the operation of the watercraft; and a valve unit fluidly connected to the second driving hydraulic actuator and selectively fluidly connecting the hydraulic system to the at least one other hydraulic system, the valve unit having a first and a second position, in the first position of the valve unit, the valve unit inhibiting any fluid connection between the hydraulic system and the at least one other hydraulic system, in the second position of the valve unit, the valve unit fluidly connecting the hydraulic system to the at least one other hydraulic system and actuating the second driving actuator causing a first flow of fluid to flow from the hydraulic system to the at least one other hydraulic system.
