It is already known (from Patentgesu oh 3 64 364) that the piston 1 is provided with a transverse bore perpendicular to the piston axis and that a piston barrel with the piston barrel roller 6 is swiveled into said transverse bore. It is also known that through the piston channel 8 pressure medium from the cylinder chamber is introduced into the piston tube control channel 5 and τοη dart through the piston “so tube channel 7 is channeled into the hadialbalanation field 6 in the piston tube” furthermore iat rewarded that the oil tube & h 2 with piston tube guide 3 from -tet a * in can "It is also known that the pressure medium is radially inside the pressure medium in the pressure medium field 15 on the.
