2.2.2 One-way restrictor
valve
One-way restrictor valves are hydraulic components for controlling
consumer speeds.
Speeds can be influenced only by modifying the volume flow:
a low volume flow results in low speed
a high volume flow results in high speed.
Item Designation Remark
1 Valve Designed as a hexagon, the hexagon areas allow the free circulation
and the hexagon points guide the valve in the bore.
2 Restrictor Designed as a notch in the valve seat.
A Port When the volume flow enters via port (A), the valve (1) is forced open
and a high volume flow passes unrestrictedly over the hexagon areas of
valve (1) to port (B).
B Port When the volume flow enters via port (B), the valve (1) is pressed onto
the seat so that only a low volume flow passes over the restrictor (2) to
port (A).
