An Octopus Hydraulic Linear Actuator is a simple, effective way to drive the rudder on a boat equipped with a mechanical steering system. The linear actuator is an assembly of an Octopus reversing pump and a marine hydraulic cylinder. This assembly is mounted on the rudder tiller-arm or quadrant. When the autopilot is not in use the cylinder runs freely along with the rudder. When the automatic pilot is in use a solenoid valve on the actuator closes and locks the cylinder. Steering signals from the pilot are now fed to the D.C. motor, which drives the pump to move the cylinder back and forth. De-energized, the solenoid valve immediately disconnects the automatic pilot from the rudder. The actuator has a small translucent oil reservoir, making it easy to check fluid levels. These actuators have only five moving parts. Mechanical simplicity gives our product reliability and ease of service when compared to complicated gear and screw actuators, making our units a favorite for offshore mariners. These actuators are shipped from our factory completely filled with oil and require no additional plumbing.

Patently Better

Octopus offer a full range of powerful, low current consumption hydraulic linear drives designed for long passage making. An independent comparison by the University of British Columbia* showed that Octopus piston pumps are three times more efficient than a gear pump and can be expected to halve the battery consumption when compared to a competitorís unit, therefore doubling the effective range of the autopilot on one battery charge.

The drives are available either with the pump mounted on the cylinder or mounted separately.

Adjustable Flow Rate

A linear drive that does not have variable flow (unless dedicated to a range of yachts) will be operating either too quickly or too slowly in 90% of cases. Autopilot manufacturers get around this problem by adjusting the output to the pump to compensate. However, this either forces the pump to operate for longer periods of time which increases power consumption and wear on the parts, or the pump will operate at high pressure for short periods of time - also putting unnecessary strain and wear on the system.

Octopus variable flow reversing pumps precisely control the speed of the ram, reducing battery consumption, pressure, strain and wear on the hydraulic system.
