Claims (2)

1. Поршень для двигателя внутреннего сгорания, содержащий канавки для поршневых колец и наклонную маслоулавливающую кольцевую выемку, размещенную между канавками и отделенную от них верхней и нижней перемычками, отличающийся тем, что боковая поверхность кольцевой выемки в поперечном сечении выполнена по параболе, нормаль к которой в точке выхода параболы на верхнюю перемычку лежит на боковой поверхности поршня.1. A piston for an internal combustion engine, comprising grooves for piston rings and an inclined oil collecting ring recess located between the grooves and separated from them by upper and lower jumpers, characterized in that the lateral surface of the annular recess in the cross section is made along a parabola, normal to which the parabola exit point to the upper jumper lies on the side surface of the piston. 2. Поршень по п. 1, отличающийся тем, что длина нормали из точки выхода параболы на верхнюю перемычку, фокальный радиус-вектор, проходящий через эту точку, и фокальный параметр параболы определены соотношением
N=r=2p=(0,15-0,03)D,
где N - длина нормали,
r - радиус-вектор,
p - фокальный параметр,
D - диаметр поршня.2. The piston according to claim 1, characterized in that the length of the normal from the point of exit of the parabola to the upper jumper, the focal radius vector passing through this point, and the focal parameter of the parabola are determined by the relation
N = r = 2p = (0.15-0.03) D,
where N is the normal length,
r is the radius vector
p is the focal parameter
D is the diameter of the piston.
