    A solenoid valve including an armature having axially spaced circumferential grooves and magnetizable discs extending into the grooves. The discs are formed in at least two parts to permit assembly of the discs into the grooves and are offset in the grooves. A winding is provided which when energized polarizes the discs so that adjacent discs have opposite magnetic polarity.

    CO CO D The invention relates to solenoid-type valves used, for example, in engine control systems for internal combustion engines. Designs of solenoid valves are known, containing cylindrical bark of ferromagnetic material, installed with the possibility of returning but-moving movement and made with annular grooves on the cylindrical surface, and a sectional winding consisting of separate annular coils, each of which is enclosed between disks of ferromagnetic material . The inner edges of the discs of such a valve are radially spaced from the outer surface of the core, as a result of which, upon excitation of the windings, the ribs, defined by the presence of annular grooves, align with the inner edges of the discs C1. An increase in the force can be achieved by changing the shape of the working gaps by inserting the inner-edges of the screws into the grooves of the core, however, in the well-known device, this cannot be achieved without considerable complication of the structure. The purpose of the invention is to improve the manufacturability of structures while ensuring the mating of the core to the disks. The goal is achieved by the fact that in a solenoid valve containing cylindrical bark of ferromagnetic material, installed with the possibility of reciprocating movement and made with annular grooves located on its periphery at different levels perpendicular to the axis of displacement of the box, the sectioned electric winding is from separate ring coils, each of which is enclosed between disks of ferromagnetic material covering the measles, and is adapted to provide When an electric current of opposite magnetic polarity flows, the peripheral areas of the end surfaces of adjacent disks are in contact with each other, and their number is equal to the number of cylindrical grooves on the cortex, each disk of ferromagnetic material is divided into at least two parts and is set that its inner edges, covering the measles, fit into the corresponding cylindrical grooves of the core. To ensure the normal operation of the device, the thickness1 of the inner edges of the disks is selected depending on the width of the grooves. so that when the excitation is removed from the winding, the discs are displaced in the axial direction relative to the grooves. FIG. 1 shows a solenoid valve, a slit; in fig. 2 - the same top view (on a reduced scale). The valve contains the main body 1 of the cup-shaped form, made in one piece with the wall of the base of the body and having an elongated part of 2 steps with an outlet 3. The extended part consists of their inclined surface 4 and step 5. During operation, the inclined surface 4 is located against the additional surface, enclosed in a hole passing through the / cylinder head of the engine with ignition from compression, and the exhaust port 3 serves to direct the fuel into the engine combustion block. A stepped hole is formed inside the elongated part, at the narrow end of which an outlet opening 3 is placed. The valve element b is integral with the hollow cylindrical bark 7, the measles are mounted slidably along the hollow cylindrical guide 8, which is made integral with the element of the partition 9 located in the open end of the body 1. 8, is in communication with the fuel inlet 10, and a spiral pressure spring 11f is located in the air inlet. This spring acts on the valve element, pressing it against the bearing surface. Channels are formed in the valve element so that fuel can flow from the inlet 10 to the outlet 3 when the valve element is open. ; A plurality of axially arranged annular grooves 12 / cat-rye form ribs 13 are formed on the outer surface of the core 7. The ribs outer surfaces have a cylindrical shape, their lateral surfaces are perpendicular to the axis of the valve element. These perceptions (the surfaces of attraction j are formed by the end wall of the groove 12 closest to the valve element B.. Other boxed surfaces —the rider iji is inclined, so that the thickness of each edge decreases as the distance increases from 6ci; Yaklonnye (the surfaces also form a groove 12 ( the farthest from the element 6 is claan), the disks 14 are grooves 12, each disk is diametrically divided
    into two parts 15 and 16 (Fig. 2 /. The outer-face parts 17 of each disk have the form of flanges with an increased thickness compared to the rest of the disks; in addition, each flange part defines a groove on one side of the squeak, so that when the discs are inserted into the housing, the flange of the adjacent one enters the recess of the single disc. The inner surface of the wall of the base of the copus is provided with a step that is located in the recess of the adjacent disc. The front partition has also a recess for installing the flange of the adjacent head disk ..
    The inner end portions of the discs on one side form surfaces parallel to the attraction surfaces, and on the other side, inclined i surfaces, since the thickness of the inner end portions of the discs decreases towards the bark. . .
    Between adjacent pairs of disks are annular parts of a winding 18, which together form a solenoid. The parts of the winding can be connected in series or in parallel, but in both cases they are placed so that the direction of current flow in the adjacent parts of the winding is opposite. As a result, when an electric current is supplied to the winding, the adjacent disks 14 assume an opposite magnetic polarity. Clearances between
    the discs and the surface of attraction are smaller than the gaps between the inclined surfaces of the ribs and} (Fig. 1, and as a result, an attraction arose, made the core and valve element 6 move against the spring 11 action. As the movement , the size of the air gap is reduced, and the force acting.
    About measles, increases.
    In accordance with another variant, the magnitude of the movement of the core may be limited by the contact of the ribs with the discs, the element of the perennial 9 may be located so as to serve as a stop surface for the core.
    Discs and winding parts may
    0 are assembled on the bark, and the neighboring ones are made to the winding parts on the outer side of the case, and then the node can be inserted into the case through its open end. The inner surface of the open end of the case; Ca is provided with a thread for screwing in the retaining ring 19, which, when tightened, holds the partition member and the discs in the assembled state. Connections between parts of the windings can be made using locking grooves (not shown J, formed in the flange parts of the discs. Any suitable type of connector can be provided, for example, on the housing or the sub-micro element 9.
