The piston skirt (24) assembly may include two separate portions that each have at least one skirt support (80) securing the respective skirt portion to the strut.
The piston skirt covers an upper portion of a piston rod (4) when the piston is mounted on the piston rod.
A wrist pin extends within the pin bores and the connecting bores and the skirt bore along the second axis to interconnect the piston head and the connecting rod and the piston skirt.
An exemplary piston assembly may include a piston crown and a piston skirt that is received in a central opening of the crown.
The piston (1) may further comprise at least one piston ring groove (10, 12, 14) arranged in the piston skirt (6).
Said cooling channel, at its end that is open towards the piston shaft, is closed by a correspondingly shaped wall part (5) that is radially split at least once.
An outlet port (122) of each piston chamber (110) and an associated temperature compensated valve (124) and a pressure relief valve (126) of each piston chamber control the clutch actuation.
