The valve PVRM3 is the directly controlled 3 way [2]
reducing valve controlled by a proportional solenoid. In
basic position (zero coil current) the channel A is
connected to tank via channel T, whereas the channel P
is closed. In this state the reduced pressure in channel A
equals zero. With increasing the coil current the
solenoid force gradually increases [1] and shifts, after
overcoming the spring pretension [4], the spool [3] to
position gradually decreasing the opened way A-T until
the pressure in channel A increases due to opening the
way P-A. The reduced pressure is led through the spool
boring into the space of the actuating system, where it
acts on the smaller spool are. With increasing the
reduced pressure in channel A, the created force acting
in direction of the solenoid force increases and assist in
overcoming the hydrodynamic forces acting on spool.
For every value of the coil exciting current, there is a
state of equilibrium of forces between the solenoid force,
spring force, force acting on the smaller spool area and
hydrodynamic forces. The reduced pressure is exactly
defined by coil current, as shown on the static pressure
characteristic. In basic variant a part of the valve is
exhibited to influence of the environmental atmosphere
and the coil zinc plated.
