Definitions

  • a hydraulic fluid connection is preferably provided with a hydraulic fluid line which pierces the cylinder lock and / or the cylinder head support of the corresponding end side.
  • the hydraulic fluid line with the hydraulic fluid connection is in fluid connection with the corresponding pressure chamber and supplies it with hydraulic fluid.
  • FIG 4 shows an alternative embodiment of a synchronous cylinder 1 according to the invention, in which, unlike in the first embodiment according to FIGS Figures 1 to 3 a bypass device 50 in the form of a bypass line 103 is arranged outside the housing and connects the pressure chambers 42 to one another via respective bypass valves 52.
  • the bypass line 103 replaces the annular gap between the outer cylinder 10 and the inner cylinder 20 according to the embodiments of FIG Figures 1 to 3 .
  • the bypass line 103 has the same technical effects as the annular gap 51 according to the embodiments of FIG Figures 1 to 3 .
  • the Figure 5 shows an embodiment of a synchronous cylinder 1 not according to the invention in a side view and one along the line AA from Figure 5 sectioned frontal view. From the front view according to Figure 5b it can be seen that four bypass lines 103a-d are arranged inside the housing of the synchronous cylinder 1 outside the outer cylinder 10. These bypass lines 103a-d replace the bypass line 103 according to FIG Figure 4 in its entirety the annular gap 51 according to the embodiments of FIG Figures 1 to 3 .
  • the bypass lines 103a-d connect in the same way as the bypass line 103 according to FIG Figure 4 the pressure chambers 42 of the synchronous cylinder 1.
