Abstract

The invention relates to mechanical engineering and can be used in reciprocating machines - compressors, internal combustion engines. The purpose of the invention is to improve the performance by increasing the stability of the piston during its movement in the cylinder. The supporting protrusions 10, 11 of the first group are spring-loaded in the radial direction due to the fact that they are made on two elastic parts of the skirt, separated by a groove 18 parallel to the axis of the cylindrical surface of the head, and separated from the head by grooves 19, 20 perpendicular to the groove 18. the protrusions are located in the median plane 15 from different sides of the plane 14. 2 Cp. f-ly, 4 ill.

The invention relates to the magnetomachine and can be used in reciprocating machines - compressors, internal combustion engines.
The aim of the invention is to improve the performance by increasing the stability of the piston during its movement in the cylinder.
FIG. 1 shows the proposed piston, side view; FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view along arrow B in FIG. one; in fig. 4 is a view of CTpenke B in FIG. one.
The piston contains a head 1, lugs 2, 3 and jub- uu 4 connected to the head. The head 1 has a cylindrical circular surface 5 with an axis 6. A hole 7 Cl of a piston pin (not shown) is made in the bosses 2, 3. The axis 8 of the hole 7 is perpendicular to Axis 6. On the skirt 4, on one side of Plane 9, drawn through axes 6 and 8, two support lugs 10 and 11 of one group are made, and on the other side of the same plane 9, four support lugs 12 and 13 other groups. The centers of the protrusions 10 and 11 are located in the plane 14, which passes through the axis 8 of the aperture 7 perpendicular to the axis 6, from different sides of the ft of the diametral plane 15 of the head i, perpendicular to the axis 8 of the aperture 7. and 13 are located in the median plane 15 from different sides of the plane 14.
The supporting protrusions 10, 11 of the first fpynnbi are spring-loaded in the radial direction due to the fact that they are made on two elastic parts 16, 17 of the skirt 4, separated by a groove 18 parallel to axis 6 and separated from the Head 1 by grooves 19, 20, essentially Perpendicular to the groove 18 (Fig. 3). Each elastic part 16, 17 of the skirt 4 is made with a variable thickness around the circumference of the piston, increasing from the groove 18.
During operation of the poroline machine, the piston moves reciprocally in a cylinder (not shown). Thanks to the location of the support lugs 10 - 13, they are all

constantly in contact with the surface of the cylinder.

Claims (3)

1. A piston for a piston machine, comprising a head with a cylindrical outer surface, connected
with a lug head with a hole for a piston pin, the axis of which is perpendicular to the axis of the cylindrical surface of the head, and a skirt with supporting protrusions placed in two groups on opposite sides of the plane of the hole for the piston pin passing through the axis and the axis of the cylindrical surface of the head, characterized in , in order to improve performance by increasing the stability of the piston during its movement in the cylinder, each group of supporting protrusions is formed by two projections, while the centers of the supporting projections of one group of placed in the plane passing through the axis of the hole for the piston pin perpendicular to the axis of the cylindrical surface of the head, on different sides of the diametral plane of the head passing perpendicular to the axis of the hole for the piston pin, and the centers of the supporting projections of another group are located in the specified diameter plane from different the sides of the plane passing through the axis of the piston pin bore perpendicular to the axis of the cylindrical surface of the head.
2. A piston according to claim 1, characterized in that the supporting protrusions of at least one group are made on two elastic parts of the skirt, separated by a groove parallel to the axis, the cylindrical surface of the head,
and separated from the head by grooves perpendicular to the first said groove.
3. A piston according to claim 2, characterized in that each is elastic
part of the skirt is made with a variable thickness around the circumference of the piston, increasing from the groove parallel to the axis of the cylindrical surface of the head.
