Hydraulic Control Systems

  • TeleflexMorse is the world’s largest manufacturer of
    marine hydraulic controls
  • Proven performance and reliability for over 30 years
  • Dependable control for luxury cruisers, workboats and
    commercial fishing boats
  • Nothing moves boats better
  • A hydraulic control is a liquid link between a
    sender and an actuator

    • Provides pure energy in motion
    • Without friction
    • Without backlash
    • No lost motion
  • Up to four stations is possible depending on length
    of tubing run
  • Unique and highly accepted feel
  • Simple installation

Multiple Station Synchronization

Each Hynautic sending, unit contains a special
valve assembly which permits full synchronization. With just a few movements
of one handle, all stations are synchronized. Any adjustments are automatically
made as the system is operating.

Ease of installation

Unlike bulky mechanical or cable systems, Hynautic
uses lightweight nylon tubing which is more pliable and less susceptible to
abrasion. Components are easily mounted and the senders are hydraulically connected
to the slaves, avoiding the troublesome linkage boxes found in mechanical* systems.

No
Throttle Feedback

By incorporating a double check valve in the system,
throttles cannot be retarded by heavy-duty governor springs common to most large
engines. Quick disconnect linkage at the engine allow for independent throttle
operation while servicing the engine.

Quality Materials

All component bodies are made of 6061-T6 aluminum.
Sender heads and handles are anodized aluminum; sender shafts are stainless
steel. Cylinder barrels are brass.

Neutral
Clutch Detent

A spring-loaded clutch detent on each clutch slave
insures that all stations register a distinct feel when the transmission is
in neutral. Also available is an optional Neutral Safety Switch Kit which prevents
the engine from starting while transmission is in gear.

All Hynautic control systems’ incorporate certain high-tech
components. These hydraulic components are interconnected either nylon or copper
tubing.

CL-B4
or CR-R4 Senders

Separate left and right sending units are interchangeable
as either clutch or throttle controls. The sender face is brushed anodized aluminum,
as is the handle. Optional mounting plate simplifies side-by-side installation.

R-13
Reservoir

The reservoir maintains the fluid reserve and
pressure for the hydraulic system. Clear sight tube makes visual fluid inspection
easy. The lower charging valve section keeps all parts of the system under positive
fluid pressure.

SS-04

Transmission slave with neutral detent is mounted
directly on the transmission.

ST-06

Throttle slave directly attaches to the engine’s
throttle linkage. It is equipped with a pilot check valve to prevent throttle
feedback.

A Guide Hynautic Controls

When the control handle of the Sending
Unit
is moved, mechanical energy is transformed into fluid energy by
means of a rack and pinion attached to an internal piston. This piston expels
fluid from the sending unit into all other control heads and the slave unit.
The pistons in each of these units are thus moved an equal distance, causing
a corresponding movement in the lever of each.

To control synchronization, the piston; in each sender and slave contains two
small valves. These are opened when the piston reaches the end of the stroke,
allowing excess fluid to pass through the piston and into the system. Controls
can be synchronized, if necessary, by rotating the lever arm of any control
head from stop-to-stop.

The Reservoir maintains the extra fluid and constant pressure
head (80 psi) for the system. The flow of fluid to and from the reservoir is
regulated by small valves located in the charging section. As fluid expands
due to engine temperatures, the excess liquid is expelled into the reservoir
at a controlled: rate. Likewise, fluid is returned to the system as temperature
drop.

Each Slave Unit contains an over-travel bungee in its linkage
to the engine or transmission. This device assures that the slave piston will
reach end stroke in each direction. Otherwise, the balance between senders and
slave cannot be maintained. The transmission slave unit has a mechanical detent
to indicate a neutral position. Each throttle slave-is equipped with an internal
pilot check valve which prevents control arms from drifting back to an idle
position.
