Steering Control Units
The Char-Lynn ® steering control unit (SCU) is fully
fluid linked. This means there is no mechanical
connection between the steering unit, the pump
and the steering cylinders. The unit consists of a
manually operated directional control servo valve
and feedback meter element in a single body. It is
used principally for fluid linked power steering
systems but it can be used for some servo-type
applications or any application where visual
positioning is required. The close coupled, rotary
action valve performs all necessary fluid directing
functions with a small number of moving parts.
The manually actuated valve is coupled with the
mechanical drive to the meter gear. The control is
lubricated and protected by the power fluid in the
system and can operate in many environments.
Char-Lynn power steering control units offer the
following advantages:
• Minimizes steering linkage—reduces cost, provides
flexibility in design.
• Provides complete isolation of load forces from the
control station—provides operator comfort.
• Provides continuous, unlimited control action with
very low input torque.
• Provides a wide selection of control circuits and
meter sizes.
• Can work with many kinds of power steering pumps
or fluid supply.
