    A starter motor of the pre-engaged type has a stator, a rotor, a rotor shaft and a pinion assembly mounted on the rotor shaft for rotation therewith and axial movement relative thereto into and out of an operative position. A solenoid is mounted in a casing of the motor and includes a coil and a plunger assembly. The plunger assembly includes a spring biased plunger carrying a plate having a slot therein. A nylon moulding is mounted in the slot and biased by a spring against an end of the slot remote from the plunger. The nylon moulding itself has a pair of slots therein which receive respective ends of a bifurcated lever. The lever is pivoted intermediate its ends and is provided with a yoke connection with the pinion assembly. The bifurcated form of the lever and the slots in the nylon moulding reduce wear of the lever in service.

    The invention relates to engine building, in particular to starters for starting an internal combustion engine (two).
    Known starters for starting an internal combustion engine, 5 comprising a rotor shaft, an electromagnetic relay with an armature equipped with a rod with a longitudinal groove, in which a spring-loaded plate iq is mounted relative to the rod, iq is connected to a rod and a gear drive with a rod, the lever having its upper part placed in the groove of the rod £ 13 · However, the device is subject to significant wear during operation, which 15 reduces the reliability of the starter.
    The purpose of the invention is to increase the service life of the starter.
    The goal is achieved by TeMj that the lever in the upper part is made in the form of a fork with teeth covering the rod, and the plate has ’windows for accommodating the teeth of the fork, and the plate is made of plastic. In addition, the plate 'may have a trapezoidal recess located between the windows from the side opposite the anchor, and the teeth of the fork can be made convex to provide relative movement of the lever and the plate.
    In FIG. 1 shows a starter, partially longitudinal section; in FIG. 2, view A in FIG. 1 without teeth of a lever fork (increased); in FIG. 3 - plate in the plan; in FIG. 4 - lever.
    The starter comprises a housing 1 with a stator 2 and a rotor 3 located on it, on the shaft 4 of which a drive 5 with gear 6 is mounted. The gear 6 is moved along the shaft 4 by an electromagnetic relay 7 with an armature 8 through a lever 9 made in the upper part in the form of a plug 10 with teeth 11, and fixed in the starter on the axis 12 with the possibility of rotation. The lower bifurcated part 13 covers the actuator 5 and mates with the protrusions 14. The armature 8 of the relay 7 is provided with a rod 15 with a longitudinal groove 16, in which a plate 18 made of plastic, for example nylon, pressed by a spring 17, is mounted with a possibility of displacement relative to the rod 15. The fork 10 of the lever 9 covers the rod 15, while the teeth II are included in the window 19 of the plate, made on different sides from its axis. To ensure relative movement of the lever 9 and the plate 18, the teeth 11 are made convex. The plate 18 from the side opposite the anchor 8 has a trapezoidal recess 20 located between the windows 19 and mated to the end of the groove 16 of the rod 15.
    Stater works as follows.
    When the starter is turned on, the armature 8 of the electromagnetic relay 7, being retracted, moves the rod 15 through the spring 17 and the plate 18, the lever 9, the teeth of the II fork 10 of which are included in the window 19 of the plate. Turning around the axis 12, the lever 9 with the lower part 13 through the jack ”! 14 moves the actuator 5 with gear 6 towards the flywheel of the starting engine (not shown in the drawing). When the anchor 8 of the relay 7 is fully retracted, the gear 6 does not reach the stop on the shaft 4 for a certain amount, the contacts of the starter motor close, the rotor shaft 4 starts to rotate. The axial force resulting from the engagement of the drive-shaft 4 of the rotor 3, the gear moves along the shaft 4 until it stops on it. In this case, the lever 9 also moves, the fork 10 in its upper part with the teeth 11 moves the plate 18 towards the armature 8 of the relay 7, compressing the spring 17. The trapezoidal recess 20 provides a reliable fixation of the plate 18 with the rod 15 when it is returned to its original position.
    The proposed design of linking the lever with the armature of the electromagnetic relay increases its reliability and increases the service life of the starter.

    38 2 BAT with bosses 14. Anchor 8 of the relay 7 is provided with a rod 15 with a longitudinal groove 6, in which a plate 18, made of plastic, for example nylon, is displaced relatively to the rod I5 by a spring 7. The fork 10 of the lever 9 covers the rod 15, with the tooth And entering the windows 19 of the plate, running on opposite sides of its axis. To ensure the relative movement of the lever 9 and the plate 18, the teeth are filled with convex. The plate 18 on the side opposite to the bore 8 has a trapezoid notch 20 placed between the windows 9 and adjoined to the end of the groove 16 of the rod 15 The stater works as follows When the starter is turned on the bore 8 of the electromagnetic relay 7, retracted, moves the stem t5 through the spring 17 and the plate 18, the lever 9, the tooth P of the plug 10 of which is inserted into the windows of the 19 plates. Turning around the axis 12, the lever 9 and the lower part 13 through the bridge 1 14 moves the drive 5 with the gear 6 towards the flywheel of the engine being started (not shown in the black). When the crust 8 is fully retracted, the relays 7 gear 6 by a certain amount does not reach the stop on the shaft 4, the contacts of the starter motor close, and the rotor 4 begins to rotate. The axial force that occurs in the engagement of the drive-shaft 4 of the rotor 3, the gear wheel moves along the shaft 4 until it stops on it. In this case, the lever 9 also moves, the fork 10 in its upper part with the teeth 11 moves the plastic 18 towards the core 8 of the relay 7, squeezing the spring 17. The trapezoid notch 20 provides a fixture of the plate 18 with the rod 15 when it returns to its original position. The proposed design of the conjugation of the lever to the cortex of the electromagnetic relay increases its reliability and increases the service life of the starter. Claim 1. Starter for an internal combustion engine comprising a rotor shaft, an electromagnetic relay with a crust provided with a rod having a longitudinal groove, in which a spring-loaded plate connected to the rod with a rod and connected with a gear i differing from that, in order to increase the service life, the lever in the upper part is made in the form of a fork with teeth covering the rod, and in the plate there are holes for accommodating the teeth of the fork, and the plate is made of plastic.
