    Abstract: The design and construction of past piston assemblies having a wrist pin bolted to a connecting rod had excessive structural components requiring more complex machining procedures and tooling. Additionally, the loading and bolting patterns allowed the wrist pin to flex about the central axis of the piston assembly causing ultimate failure of the design. The present invention overcomes these problems by providing a piston assembly (10) utilizing a bifurcated connecting rod (36) and a piston (14) having a pair of outer legs (24) and a central leg (26). The outer legs (24) and the central leg (26) contact a wrist pin (44) in three locations substantially distributing the forces across the wrist pin (44) uniformly. A connecting means (54) centrally connects the piston assembly (10) shortening the overall length of the piston assembly (10). This results in a simplified forging or casting process, a more easily machinable piston (14), and a higher reliability design with improved load capacity.

    Abstract: A piston (22) for an internal combustion engine (10) has a crown (60) and peripheral wall to carry a piston ring (68). A support (80) extends between the wall and a bearing housing (84) to receive the connecting rod (24). A cylindrical support member (100) also extends from the wall around the support to a skirt. The support member (100) is radially inset from the wall and a cylindrical bearing member is located on its radially outer surface (148).

    Abstract: The aim of the invention is to provide a cooled multi-component piston (1) of simple design in which the hollow annular space (9) in the piston head (2) for the cooling oil is closed off underneath. This is achieved with a sheet-metal ring (10) with a collet (15) which fits in a recess (16) in the piston-ring wall (5), the sheet-metal ring being biased via a retaining clip (18) against the shaft bush (8).

    Abstract: The invention relates to a piston with swirl-inducing device for Diesel engines, where a recess is machined in the upper part of the piston which is in communication with the engine's main combustion chamber when the piston is built-in. The essence of the invention lies in that said swirl-inducing device (4) comprises a heat storage insert (5) fixed in the piston's (1) recess (3) axially spaced from a bottom plate (6) of the recess (3) by way of a reduced heat transfer connection and provided with a series of gas turbulence inducing ducts (12) through which a space (14) of the recess (3) created by said axial spacing (7) below the heat storage insert (5) is in communication with a space, e.g. the main combustion chamber (13) above the heat storage insert (5).

    Abstract: In a process for improving the sliding of alternating pistons of thermal engines while counteracting the tilting movement of said pistons, a pressure gradient is generated by the action of vibrating elastic means (1, 1a) resistant to the thermal and chemical stresses produced by the explosion, and by the usual infiltration of the driving gases into the piston groove, said means being mounted behind the piston ring. The pressure gradient results in the formation of a permanent pressurized toric seal during operation of the engine.
