A spring packing ring, or any of several such rings, for a piston.
Ring fitted into the grooves in a piston. There are two types: compression rings for sealing the pressure in the engine combustion chamber and oil rings to remove excessive oil from the cylinder wall.
A sharp edged ring mounted on the piston of gas operated automatic and semiautomatic firearms which makes a close seal between the piston and cylinder wall, and by a scraping action reduces the accumulation of carbon in the cylinder.
seal consisting of a split metal ring that seals the gap between a piston and the cylinder wall
a simple spring, when a spring is over-heated it looses tension
a simple spring, when a spring is overheated it will loose tension
Metal ring placed in a circumferential groove in the exterior of a piston to create a gas seal between the piston and cylinder wall.
Hardened metal ring, which is a spring, fit in a groove running round the piston to ensure a gas-tight seal between the piston and cylinder wall.
One or more rings around the circumference of the piston, used as a seal between the piston and the inside cylinder wall.
An open-ended ring that fits into a groove on the outer diameter of the piston. Its chief function is to form a seal between the piston and cylinder wall. Most automotive pistons have three rings: two for compression sealing; one for oil sealing.
Spring steel ring that provides a seal against the cylinder wall when it is fit around the outside of a piston.
A piston ring is an open-ended ring that fits into a groove on the outer diameter of a piston in an internal combustion engine.
