Dashpot, has inner tube, which forms cylinder tube, outer tube surrounding the inner tube and confining annular space together with inner tube whereby first locking piece is connected with inner and outer tubes

Dashpot (1) has an inner tube (3), which forms a cylinder tube, an outer tube surrounding the inner tube and confining an annular space (8) together with the inner tube. First locking piece (4), which is connected with the inner and outer tubes (2), seals the annular space outwardly at the concerning end and contains a bore coaxial to the inner tube. A piston bar (6) is inserted in a sealing manner into the first locking piece through the bore (12). A piston fixed to the piston bar runs into the inner tube and is sealed adequately opposite the inner wall of the inner tube in order to divide the space in the inner tube into two cylinder chambers (48,49). A second locking piece is connected with the inner and outer tube and which seals outwardly the annular spaces at the concerning end. A stepped bore (28) containing in the second locking piece (5) through this stepped bore a duct is fed through, which connects the adjacent cylinder chamber with the annular space according to the flow. A restrictor (39) is movable in the stepped bore and protrudes in the duct (29) in order to control the flow section in the duct. Second duct (47) connects the other cylinder chamber on the other side of the piston (7) with the annular space according to the flow. Ein Öldämpfer weist zwei koaxial ineinander steckende Rohre auf, die beide endseitig durch zwei Verschlussglieder verschlossen sind. Durch eines der Verschlussglieder führt die Kolbenstange hindurch, während das andere Verschlussglied eine Drosseleinrichtung enthält, über die der Strömungswiderstand regulierbar ist, den das Dämpferöl beim Verschieben des Kolbens überwinden muss.
