In 1925, Piston Ring bought the No-Leak-O Piston Ring Company, allowing the company to increase production of engine components. [8] [10] After acquiring Accuralite Company in 1931, the company changed its name to Sealed Power Corporation and also started manufacturing piston rings, pistons and cylinder sleeves for various military applications ...
A piston ring is a metallic split ring that is attached to the outer diameter of a piston in an internal combustion engine or steam engine. The main functions of piston rings in engines are: Sealing the combustion chamber so that there is minimal loss of gases to the crank case.
Federal-Mogul Powertrain designs and manufacturers original equipment powertrain components and system protection products in the United States and internationally, its production line consists of different products, ranging from powdered metal parts to space suits, including engine bearings, pistons, piston pins, piston rings, cylinder liners ...
The design of the seal ring must allow for minimizing distortion and maximizing heat transfer while considering the secondary sealing element, drive mechanism, spring and ease of assembly. Many seal rings contain the seal face diameters, although this is not a requirement of the primary ring. The seal ring always contains the balance diameter.
Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some limited contact-sealing action that creates the seal.
A taper-joint stopper with PTFE Sealing Ring. Optical transparency of the narrow sealing ring pressured by glass joint (right). Glass taper joints can be sealed hermetically with PTFE sealing rings (high vacuum tight, air leakage rate 10 −6 mBar × L/sec and below), [ 6 ] o-rings (optionally encapsulated o-rings), or PTFE sleeves, [ 7 ...

Bearings, oil pumps, piston rings, valve springs, flywheels, transmissions, driveshafts, and differentials all act as parasitic loads that rob the system of power. These parasitic loads can be divided into two categories: those inherent to the working of the engine and those drivetrain losses incurred in the systems that transfer power from the ...
