摘要： A two-part piston for an internal combustion engine, comprising a piston head and a piston skirt connected with the piston head in articulated manner, by way of a piston pin. The piston head has a piston crown that is followed by a cylindrical circumference surface having a top land and a ring belt. The piston head can include a ring-shaped circumferential cooling channel disposed within the piston head. The opening of this cooling channel faces the piston skirt, and is closed off with a seal element. There is a seal element that has a first free end that is held between piston head and piston skirt, or rests against an outer wall of the cooling channel. The seal element has a second free end that rests against the piston head, and wherein the seal element has a bottom that lies on a surface of the piston skirt that faces the cooling channel.

摘要： A cooling channel cover for a one-piece piston of an internal combustion engine, the piston having a closed cooling channel that runs around inside the piston crown, at the level of the piston ring band, and a ring-shaped recess provided between the piston ring band and the piston shaft, wherein the piston shaft is connected with the piston hubs suspended on the piston crown. In such a piston, an easy to assemble cooling channel cover is achieved in that a one-piece, plastic spring steal ring, U-shaped in cross-section, having radially angled outer and inner shanks around the circumference, has at least one film hinge running around the circumference of the ring. The film hinge allows at least one radial deflection of at least one of the shanks, in such a manner that in order to close off the cooling channel, the shanks engage in a stepped conical recess on the inner edge of the cooling channel.

The piston shaft is connected with the piston hubs suspended on the piston crown. In such a piston, an easy to assemble cooling channel cover is achieved by a one-piece plastic/spring steel ring that is U-shaped in cross-section, having a ring bottom and an outer shank around the circumference, molded onto the ring bottom and angled off radially to the outside, and an inner shank around the circumference, angled off radially to the inside. The plastic ring has a first radial division having a mouth width and a second radial division, opposite the first division, which does not separate the radially angled outer shank that runs around the circumference, to form a film hinge for radial deflection of a ring shank formed by the film hinge.

摘要： Exemplary piston assemblies and methods of making the same are disclosed. An exemplary piston assembly may include a piston crown and a piston skirt that is received in a central opening of the crown. The piston crown may include a ring belt portion defining, at least in part, a cooling gallery. The crown and skirt may each further include corresponding mating surfaces that extend about a periphery of the crown and skirt. The skirt mating surface and crown mating surface may generally be secured to each other that the crown and the skirt cooperate to form a continuous upper combustion bowl surface. The skirt and crown may cooperate to define a radially outer gap about a periphery of the piston crown.

摘要： A piston for an internal combustion engine is provided. The piston crown includes an interior surface that defines at least in part a cooling gallery and a cooling gallery surface within the piston. An annular surface may defines at least in part an annular passageway that allows fluid communication between an outer surface of the piston and the cooling gallery. Opposing annular surfaces may be abutted with a predetermined force, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston. Further, an annular surface may extend into the cooling gallery to form a deflector along the cooling gallery surface, thereby limiting fluid flow from the cooling gallery to an outer surface of the piston.
