Abstract
Without changing the spring constant of a helical spring, the pressure gradient for pressure water can be changed. A driving arm (13), a plunger arm (14) and an installation arm (15) of the helical spring (23) are fixed on a rotation axis (12). A maintenance piece (24) at one end is used for maintaining the helical spring (23) and is fixed on the installation arm (15) by means of a bolt (25). A bar (28) at the other end is always fixed on a bracket (29) by means of nuts (30, 31). The helical spring (23) can changed to each installation position for the scales (S1-S4) of the installation arm (15) by loosening the bolt (25). The length (L3) to the scale (S3), and each length to the scales (S1, S2, S4) is different so that the variation of the force applied to a plunger (10) and the pressure gradient of the pressure water change according to the installation position of the helical spring (23). Therefore, without changing the spring constant, the pressure gradient for the pressure water supplied to a wefting insertion nozzle (5) can be changed.

The hydraulic pressure of the pressure (hydraulic) water of nozzle 5 is in highest hydraulic pressure P4 in time T2.Highest hydraulic pressure P4 due to helical spring 23 initial load compared with
It is little, so the highest hydraulic pressure P1 in the helical spring being set to than Fig. 1 is (with reference to Fig. 5（A）) low state.The helical spring of Fig. 4
23 positions for being installed on scale S3, so barometric gradient PS1 is not changed, the hydraulic pressure larger amplitude ground of pressure (hydraulic) water declines, and reaches hydraulic pressure
P5, terminates in time T3 wefting insertion.
