28 that reduces the likelihood of leakage from the front fork the bottom most part of the bottom part 27 is designed to be able to be attached or to be screwed in and out using a hexagonal key so that the front fork is easy both to assemble and to dismantle a piston rod holder 28 a can be integrated with the seal 28 that is threaded into this bottom part 27 the piston rod 16 is attached in a recess in the piston rod holder 28 a and the other part of the holder 28 a is screwed down from above into the abovementioned bottom part 27 due to the fact that the holder 28 a can be screwed out of the bottom part 27 the front fork is simple to dismantle by withdrawing the whole insert in an upward direction fig5 a and 5 b show the flow in the front fork through different medium flow passages 29 30 and through flow areas that are adjusted by valves 12 a 12 b 12 a u2032 12 b u2032 the valves comprise high speed valves 12 a 12 a u2032 low speed valves 12 b 12 b u2032 and standard non return valves 12 c 12 c u2032 the different types of valve are already well known and will not be described in greater detail the medium flow passages 29 30 are arranged in such a way that they are parallel in relation to each other and are connected to the common pressurizing location which comprises the pressurizing device 19 in the illustrated configuration because the passages 29 30 are parallel the flow is divided between the two medium flow passage areas and the flow speeds in the system can essentially be reduced for example halved.
