The piston further includes a coating bonded to the piston skirt so as to be juxtaposed between the skirt and the cylinder.
The lateral forging may also result in the piston skirt being decoupled from the piston head by laterally forged slots (128) formed in the lower crown part between the piston skirt and the piston head.
A method of applying the coating to the piston skirt is also disclosed.
The insert may be disposed along the first surface, and aligned with the piston skirt such that the arms of the insert form a circumference about the piston skirt.
A pair of pin bosses (34, 36) and a piston skirt (40) are cast as one piece with the piston head out of the same steel material.
The invention discloses a piston assembly with tongue-like flat seals.
Each rod is floatingly sealed with the cylinder from the side of skirt part of the piston.
The additional air supplied therethrough is sufficient to substantially reduce heat transferred from the piston upper surface portion to the skirt of the piston.
The laterally forged features may comprise undercut recesses (90) formed in the piston skirt to reduce material in the overall piston structure.
The roller is held secure by a bearing shell that is inserted in the piston base.
In the uppermost position, the skirt portion of the piston is positioned below the mid-stop shelf and seat.
An annular sealing sleeve for receiving the piston skirt (15) and the adjacent free end of the cylindrical container (10) during storage may be formed integrally with the piston actuating member (17).
The piston skirt is the lower part of the piston which will develop cracks over time due to metal fatigue.
When applied to the piston skirt, anti-friction coatings allow the piston to operate under irregular conditions, which effectively counteracts these hazards.
The piston is provided with one or more ferritic steel inserts (18), the insert or inserts (18) extending across opposed thrust faces (19, 20) of the piston (10) and forming part of the running surface of the piston skirt.
The piston (18) is formed of a structural fiber reinforced ceramic matrix composite material and then a combined first erosion-resistant and self-lubricating material is applied to a surface of a skirt portion of the piston (28).
A secondary coil (S), loosely coupled to coil (P) and tuned for resonance therewith is located in the skirt of the piston (not shown).
Greater lateral forces affect the piston skirt, which further heightens the already challenging construction and coating requirements.
This noise is caused by excessive clearance between the piston skirt and the cylinder wall, and is usually found on high mileage vehicles.
In this manner the clearance space between the piston skirt (17, 18) and the cylinder (11, 12) is closed by the outward deformation of the thin walled portion (34, 35) due to the increasing fluid pressure.
