Definitions

  • the invention relates to a piston for an internal combustion engine with an annularly arranged cooling channel, which consists of a left and a right cooling channel half and which has a first and a second opening, cooling oil through a cooling oil nozzle as a free oil jet into the first opening and thus into the cooling channel can be supplied and can be discharged through the second opening.
  • the cooling oil is injected into a first opening, the inflow opening, by means of a cooling oil jet nozzle, is then distributed in the cooling channel and is discharged through a second opening, the outflow opening. Because the cooling oil nozzle can be set at a certain angle with respect to the piston shaft, the cooling oil is not injected in equal parts into the left and right half of the cooling channel with respect to the inlet opening. This adversely affects the cooling effect of the cooling oil flow.
  • the object of the present invention is to improve a piston of the type described above in such a way that a uniform cooling effect is achieved in the entire cooling channel.
  • the coolant flow is divided when it hits the bottom surface of the cooling channel and is introduced in equal parts into the left and right cooling channel halves.
  • the rib element can be arranged offset with respect to the center of the inlet opening.
  • a particularly advantageous embodiment results when the first and the second opening have the same dimensions and are arranged symmetrically in the cooling channel, such that both the first and the second opening as inlet or.
  • Discharge opening can be used, the rib element being arranged on the left and once on the right in relation to the pin bore center line of the piston in the plan view of the cooling channel plane. In this way, the piston can be used universally and does not need to be aligned with respect to an opening.
  • Fig. 1 is a perspective view of the piston according to the invention in section and
  • Fig. 2 is a bottom view of the piston.
  • a piston 1 has in its piston head area an annularly arranged cooling channel 2, which consists of two cooling channel halves 3 and 4.
  • This cooling channel has two openings 5, 6, which can optionally serve as inlet or outlet openings.
  • coolant is injected into the cooling channel 8 through a coolant nozzle 7 (see FIG. 2) and reaches the cooling channel 2 via the associated opening 5 and can flow out via the opening 6 and the associated channel 9.
  • the coolant nozzle 7 is set at a certain angle with respect to a piston skirt 10, a rib element 11 extending in the radial direction is formed in the bottom surface of the cooling channel 2 in the region of the inlet opening 5, the position of the rib element 11 with respect to the center point the inlet opening 5 depends on the orientation of the coolant nozzle 7 such that the coolant flow is equally divided into the left and right cooling channel halves 3, 4.
  • the first and second openings 5, 6 have the same dimensions and are arranged symmetrically in the cooling channel 2, such that both the first and the second openings 5, 6 serve as inlet or Drain opening can be used, the rib member 11 being arranged in the top view of the cooling channel plane once on the left and once on the right with respect to the pin bore center line of the piston.

Abstract

L'invention concerne un piston de moteur à combustion interne comprenant un canal de refroidissement annulaire qui est composé d'un demi-canal de refroidissement gauche et d'un demi-canal de refroidissement droit et qui présente un premier et un deuxième orifices. L'huile de refroidissement est cédée sous forme de jet d'huile libre au premier orifice et donc au canal de refroidissement par une buse d'agent réfrigérant et elle est évacuée par le deuxième orifice. La surface du fond du canal de refroidissement est dotée, dans la zone de l'orifice d'alimentation, d'un élément nervuré d'extension radiale. La position de cet élément nervuré par rapport au centre de l'orifice d'alimentation est fonction de l'orientation de la buse d'agent réfrigérant de telle façon que le flux d'agent réfrigérant se répartisse en proportions égales entre le demi-canal gauche et le demi-canal droit.
