The outer piston is provided with piston rings and is supported on the inner piston by springs.

The piston crown comprises a piston top and a piston sidewall with ring grooves for piston rings (12).

The development describes a linear actuator, having movable piston segments, which permits improved damping by means of the coupling of two piston segment rings.

A second piston ring comprises two piston rings (43, 43) superposed on each other.

100461 An improved piston ring (20) for use as an intermediate piston ring in a piston assembly having three or more piston rings is provided.

The invention relates to a light-metal piston (1), in particular an aluminum piston, of a two-stroke engine, comprising at least one piston ring and an anti-rotation means (3) for the at least one piston ring.

The system also assesses the state of the contact surfaces of the piston rings and their lubrication, as well as the piston's deflection.

In another aspect, the coated article is one or more piston rings.

A piston (1) for a two-stroke crosshead engine has a number of ring grooves (2-4) for piston rings.

The invention relates to a seal for the piston of rotary piston machines, which consists of two or more rotor segments which are arranged next to one another and which seals the joint/joints between the piston segments with respect to the working fluid.

You’ll need to use your piston ring tool to remove the old piston rings.

The liner has a hardness that is within 10-20 Rc of the hardness of the piston rings carried on a piston within the liner.

Each piston in the engine housing has a groove (14), and two piston rings (15,16) are located the groove (14).

The material for sliding parts is used as a wire material for a piston ring.

Before you can replace the piston rings, it’s important to fully clean the piston.
