(Prior Art) Generally, in a fluid jet loom, a weft yarn measured and stored by a certain amount in a length measurement storage mechanism is jetted into a warp opening by a main nozzle and then assisted by an auxiliary nozzle to jet a weft yarn guide. It flies into the weft passing path composed of members and is beaten by a reed. If the jet pressure of the main nozzle and the auxiliary nozzle at the time of weft insertion and flying of the weft described above is too large, the weft is cut, and if it is too small, the tip of the weft hangs down, which causes a weft insertion error. Therefore, the control of the fluid pressure in the air tank, which determines the fluid injection pressure in the main nozzle and the auxiliary nozzle, is extremely important.

However, the pressure adjusting valve shown here is generally A proportional solenoid valve using a diaphragm as shown in FIG. 6 is used. That is, the flapper 52 attached to the electromagnetic solenoid 51 and the nozzle 53 are arranged so as to face each other, and the compressed fluid flowing from the fluid circuit (not shown) into the housing 55 through the inflow hole 54 passes through the orifice 57 and the nozzle 53 through the orifice 57. And the fuel is ejected to the flapper 52. At this time, a predetermined voltage is applied to the solenoid 51 to move the flapper 52 downward, and the diaphragm 59 vibrates up or down until the downward moving pressure becomes equal to the injection pressure of the nozzle. With the movement of the diaphragm 59, the opening amount of the relief valve 60 changes, and the amount of fluid corresponding to the applied voltage is supplied from the inflow hole 54 side to the outflow hole 62.

When the solenoid 15 is energized, the plunger 17 moves downward, and accordingly, a downward dynamic pressure is applied to the valve body 22 via the pressure receiving plate 23, and this is moved in the protruding direction to move the valve 31 and the throttle portion 29a. Increase the space between and. On the other hand, the fluid flowing into the inflow hole 32 is filled in the flow hole 28 between the step portion 36 of the valve body 22 and the valve 31, and further passes between the throttle portion 29a and the valve 31 to flow into the inflow chamber. 2
Inflow into 9. The compressed fluid passes through the fluid passage 38 of the valve body 22 from the inflow chamber 29 and reaches the fluid entry chamber 34a, and then a pressure that opposes the lower dynamic pressure of the plunger 17 is applied to the lower surface of the pressure receiving plate 23. The pressure receiving plate 23 is pushed upward. Then the valve body
22 is moved upward by the push spring 27, and the valve 31 and the throttle portion 29a are moved.
And the distance between and decreases, the amount of fluid flowing into the inflow chamber decreases, and the fluid pressure is maintained at an appropriate value.

Further, in the inflow chamber 29, the stepped portion 36 and the second protruding side fluid receiving surface 37 which are the second exit side fluid receiving surface are covered. Fourth
As shown in the figure, the pressure receiving area a projected in the axial direction of the first exit side fluid receiving surface 34 is the pressure receiving area b between the second projecting side fluid receiving surface 37 and the second exit side fluid receiving surface 36, It is a value obtained by adding the pressure receiving area e of the first exit side fluid receiving surface 34 to the difference d of c. Therefore, 2
When the pressures of the fluids on the two exit side fluid receiving surfaces 34 and 36 and the two projecting side fluid receiving surfaces 35 and 37 are equal, and the fluid pressure is significantly larger than the lower dynamic pressure of the plunger 17. However, the valve body 22 is not moved upward by the fluid pressure. Therefore, the distance between the throttle portion 29a and the upper surface of the valve 31 is maintained in proportion to the magnitude of the voltage applied to the solenoid 15, and a desired amount of fluid is supplied to the first air tank 6 from the outflow hole 33. . Therefore, the main nozzle 1 carries out weft insertion at an appropriate injection pressure.

The present invention is not limited to the above-described embodiment, and, for example, the pressure adjusting device is interposed in the first and second fluid passages 5 and 8, and the air tanks 6 and 9 are connected to the main nozzle 1 and the auxiliary nozzle 4. The pressure of the fluid sent to the pressure adjusting plate 23 is adjusted, or as shown in FIG. 5, the pressure receiving plate 23 is bent at its peripheral portion downward to form a fitting portion 39, and a valve is provided in the fitting portion 39. The upper part of the body 22 is tightly fitted to prevent fluid leakage and the accommodation chamber 21
Any modification can be made without departing from the invention, such as omitting the through hole 21a.

As described above in detail, according to the present invention, the pressure receiving areas of the fluid receiving surface on the projecting side and the fluid receiving surface on the withdrawing side formed with the valve for controlling the fluid passage amount that projects and retracts in the housing are made equal. Since the fluid pressure inside the housing and the voltage applied to the solenoid are proportionally adjusted, this configuration acts as an adjusting means, so no special adjusting means is required, and the valve operation is always maintained accurately and desired. Nozzle injection pressure can be obtained, and the structure is simplified,
Not only can the manufacturing cost be kept low, but it is also highly durable, and has the excellent effect of high-speed follow-up without malfunction.

1. A fluid pressure adjusting device having a pressure adjusting valve for adjusting a fluid pressure in a fluid passage used in a jet loom, the plunger being driven by a solenoid in a housing and having a pressure receiving plate formed at a tip thereof. And a valve body urged by the pressure receiving plate, the valve body forming an inflow chamber communicating with an inflow hole of the fluid and an inflow chamber communicating with the outflow hole between the valve body and the inner wall surface of the housing. A valve and a valve body that are in contact with a throttle section that divides the hole and the inflow chamber form a fluid passage that axially penetrates to the pressure receiving plate side, and the valve body side between the pressure receiving plate and the valve body has a first exit side. A fluid receiving surface is formed, and a first protruding side fluid receiving surface and a second exit side fluid receiving surface are formed between the valve body and the flow hole, and the valve body is connected to the inflow chamber. Is formed with a second protruding side fluid receiving surface, and is further formed on the valve body. The pressure receiving area in the sliding direction of the valve element between the first exit side fluid receiving surface and the second exit side fluid receiving surface and the first projecting side fluid receiving surface and the second projecting side fluid receiving surface. Fluid pressure regulator in equally formed jet loom.
