A flow rate control valve includes a bobbin and a plunger. On an inner circumferential surface of the bobbin, multiple protruding regions that extend in a direction parallel in an axial direction to the plunger, and a plurality of recessed grooves that form flow paths for a fluid when valve is open are provided side by side alternatingly in a circumferential direction. The multiple recessed grooves include a first recessed groove, second recessed groove, and third recessed groove that are arranged side by side sequentially in the circumferential direction. An interval in the circumferential direction between the first recessed groove and second recessed groove and an interval in the circumferential direction between the second recessed groove and third recessed groove are the same. Surfaces of the multiple protruding regions formed on the inner circumferential surface of the bobbin can be arranged at positions closer to those of one perfect circle.

According to a solenoid air valve, a flange portion of a moving core and a flange portion area of a bobbin implement a stop area defining a distance of travel of the moving core in a direction away from a fixed core. An end portion of a shaft portion of the moving core can project outward through an opening of a frame cover, so that a gap between a surface of the frame cover facing the shaft portion and a side surface of the shaft portion (distance: L) can be minimized. Consequently, a solenoid air valve having a structure allowing improvement in magnetic efficiency by making smaller the gap between the frame and the moving core is provided.

Solenoid air valve

A moving core of a solenoid air valve has a flange portion arranged on a side of a fixed core, provided in a radially projecting manner and having a first diameter, and a shaft portion having a second diameter smaller than the first diameter. Therefore, a sufficient area of magnetic pole is ensured around a rubber packing in the flange portion of the moving core. Consequently, the solenoid air valve structured such that an area of magnetic pole is sufficiently ensured even if the moving core is made thinner in order to ensure a volume of a coil body in reducing the solenoid air valve in size can be provided.

A flow control valve utilizing at least one permanent magnet and at least one magnetic coil, wherein one or more permanent magnets or magnetic coils are used to move a movable member in towards and/or away from an inflow port so as to control the flow through the port. When multiple permanent magnets are used, at least one yoke, which protrudes beyond the edges of the magnets, is place between each pair of magnets. A fixed shaft that passes through a hollow portion of the movable member is used to control the movement of the movable member, and an air vent is present near the end of the movable member that is closest to the inflow port such that the hollow space of the movable member does not form a vacuum.

Flow control valve

Textile treating compositions, comprising at least one metal- or silicon-containing organic compound selected from the group consisting of: 1) an organic titanate containing a phosphorus, sulphur or nitrogen atom, 2) a phosphorodithioate metal salt, 3) a dithiocarbamate metal salt, 4) an aluminum alcoholate, an aluminium ester or an aluminum chelate, 5) a tin-containing carboxylate salt or carboxylate ester and 6) a mercapto group-containing silane compound, are effective for preventing yarn breaking and for improving operation efficiency even at severe conditions and are praticularly useful for treating tire cord.
