摘要： An engine component assembly is disclosed having a bi-material wrist pin which secures a piston rotatably to an associated connecting rod. The bi-material wrist pin includes a cylindrical ceramic core. Surrounding the cylindrical core is a tubular shell which fixedly secures the core in relation to the shell. The shell rotatably cooperates with the piston and is fixed in relation to the connecting rod.

摘要： A two-piece piston composed of independent head and skirt portions, wherein the skirt portion is mounted by means of a wrist pin on bosses located on the lower end of members pending from the head portion, the head portion being provided with an annular recess between the combustion bowl and the ring zone, and the skirt provided with a tray on its upper end, the annular recess and the tray defining a semi-open cooling chamber. With the piston assembled, the lower end of the head portion below the ring zone and the upper end of the skirt portion, which constitutes the outer wall of the tray, define an oil baffle designed to prevent the cooling oil from flowing from the tray toward the space between the piston and the cylinder.

摘要： A hydraulically-operated piston machine includes at least one cylinder and a piston axially movably guided in the cylinder. The piston is connected to a crankshaft or the like by means of a connecting rod. The connecting rod and the piston each have spherically-shaped bearing surfaces serving for connecting the connecting rod and the piston with each other in an articulated manner. The connecting rod defines at its end connected to the piston a radially outwardly facing spherical surface portion which is arranged concentrically with the spherical bearing surface of the connecting rod. The spherical surface portion rests against the surface of a recess defined in the piston, so that a hollow space is defined between the surface of the recess and the spherical surface portion. The piston defines a bore for effecting communication of fluids between the interior of the cylinder and the hollow space.

摘要： In an internal-combustion engine, a piston pin of each piston is integrally and rigidly fixed to the small end of a connecting rod. The piston pin is pivotally coupled to the piston by way of a metal bearing interposed therebetween, and is held thus in coupled state by bearing caps respectively clamping the ends of the piston pin against the piston over an interposed metal bearing. The greater part of the piston pin is of a large diameter, and its length is only slightly less than the outer diameter of the piston, whereby a practically maximal bearing area is afforded between the piston and piston pin for withstanding forces transmitted therebetween.

摘要： An improved heat insulated piston assembly for an internal combustion engine and a method of assembly. The improved piston assembly includes a piston constructed of a sleeve having an interference fit about a heat insulated core. The core has a first end positioned flush with an end of the sleeve and has a second end located within the sleeve with a concave configured cavity formed therein. Mating in the concave configured cavity of the core is a connecting rod having a spherical ball shaped end. The spherical ball shaped end is securely held in the cavity by a retaining ring which attaches to the piston sleeve. The retaining ring allows for limited movement of the spherical ball shaped end of the connecting rod in the cavity while providing a means for returning the piston to its bottom position during the intake stroke.
