Rotary
Control Valve

This paper
firstly introduces the design concept of a hydraulic rotary servo control v=
alve
that has been uniquely developed by one of the authors. It has a feature of=
the
low cost productivity, pressure balance on the rotational parts,
unti-contamination and so on compared with the other conventional servo val=
ves.
Secondly, the basic characteristics are experimentally demonstrated such as=
unloaded
flow rate characteristics against the input signal of the rotational angle.=
In
addition, the validity of experimental load characteristics is examined by =
the
calculation curves based on the design specifications.
