ROTARY PILOT VALVE

In the rotary pilot valve of the present invention, the opening area of the port varies with a linear relation to the amount of the displacement of the spool, only when the amount of the displacement of the spool is small. In the high speed feeding range, the above-mentioned linear relation is not n...

Beschreibung
Zusammenfassung:	In the rotary pilot valve of the present invention, the opening area of the port varies with a linear relation to the amount of the displacement of the spool, only when the amount of the displacement of the spool is small. In the high speed feeding range, the above-mentioned linear relation is not necessary. Accordingly, in the above-mentioned range, the ratio between the amount of the displacement of the spool and the amount of the opening area of the port has a larger quantity than the ratio in the above-mentioned linear relation.
