    2. The piston pin according to claim 1, wherein the diameter of the central cylinder is at least 1/10 of the diameter of the pin. 3, Piston pin over pl, 1 and 2, characterized in that Some ends of at least two channels intersect in the annular groove of the top of the connecting rod, while others exit respectively into the annular grooves of bobiec bearings, each intersection point of the longitudinal axes of the channels and The ends of the longitudinal axes of the channels extending into the annular grooves of the bob-ek bearings are located along the generatrix of the finger. 4. Piston pin according to claims 1 and 2, characterized in that the channels of each pair are made independently of one another and connect the annular groove of the insert to the top
    The invention relates to mechanical engineering, namely engine building, and can be used in pistons of internal combustion engines.
    The purpose of the invention is to increase reliability.
    Figure 1 shows the piston with a finger, a general view; figure 2 - section aa in figure 1; in FIG. 3 a finger, the output rings of which are aligned along the generatrix of the finger; in fig. 4 - the finger view of each pair of channels is made independent; on fig.Z - the same, side view.
    The piston 1 contains a piston pin 2 mounted rotatably in the insert 3 of the upper head 4 of the connecting rod 5 and in the bearings 6 and 7 of the bob 8 and 9 located on both sides of the upper head of the connecting rod. The inserts 3 of the upper head 4 of the connecting rod 5 and the bob 8 and 9 are provided with annular grooves 10-12. And kao
    The screw 10 is located in the middle plane 13 of symmetry of the head 4 of the connecting rod 5 and the finger 2. In the connecting rod 5 there is a channel 14 for supplying a cooling or lubricating fluid connected
    one.
    the hooks of the connecting rod with opposite grooves of the bearings of the piston bob, and the ends of the longitudinal axes of the channels extending into the annular groove in the insert of the upper head of the connecting rod are located apart from each other on an arc of a circle 60.
    5. Piston pin in accordance with claim 4, characterized in that the ends of the longitudinal axes of the independent channels extending into the ring grooves of the bob1ec bearings are disposed one from another along the arc of a circle 120.
    6. The piston pin according to Claims 4 and 5, characterized in that the openings of the independent channels extending into the annular groove of the top of the connecting rod are alternately connected to one or the other annular groove of the bobiec bearings.
    with annular groove 10 of the upper head 4.
    In finger 2, there are three pairs of straight channels 15–20, each of which is connected at one end with a ring groove 10 and the other with one of the grooves 11 and 12 of bearings 6 and 7 of bob 8 and 9.
    The straight channels 15-20 are made in the periphery of the finger 2 with respect to the central cylinder 21, coaxial finger 2, and the diameter of this cylinder is at least 1/10 of the diameter of the finger.
    The ends 22 and 23 of at least two channels intersect in the annular groove 10, and the other ends 24 and 25 exit in respectively the annular grooves 11 and 12 of the lugs 8 and 9, with each point 26 of the intersection of the longitudinal axes of the channels and the ends 24 and 25 of the longitudinal axes of the channels that go into the grooves of the bosses are located along the generatrix of the finger 2 (FIG. 3). Channels 15-16, 17-18, 19-20 of each pair are made independent (Fig. 4) and connect the groove 10 with opposite grooves 11 and 12 of the bob piston 1, with the ends 27-32 of the longitudinal axes of the channels 15-20 exiting in the annular groove 10, are located on the arc 60, and the ends 33-38 of the channels 15-20, extending into the grooves 1 and 12, are located on the arc 120 and are alternately connected with the groove 10.
    When the engine is running, lubricating or cooling fluid through channel 1 in the connecting rod 5 goes to the bearings
