Steplessly locked adjusting device
The invention relates to a steplessly locked adjusting device capable of fixing relative movable assemblies. The adjusting device has a sealing cylinder filled with a working fluid. The sealing cylinder is divided into a first working cavity and a second working cavity by a piston and in which the piston can axially slide. The adjusting device has a piston rod which passes the second working cavity and is guided outward. The adjusting device has a first valve arranged in a first flow path from the first working cavity to the second working cavity of the piston. The first valve can be opened by the pressure of the first working cavity resistant to an elastic force when the piston slides toward a direction of the first working cavity. The adjusting device has a second valve arranged in a second flow path from the second working cavity to the first working cavity. The second valve can be opened by the pressure of the second working cavity resistant to the elastic force when the piston slides towards the direction of the second working cavity. The first flow path can be closed through a first locking device when the first valve is opened, and/or the second flow path can be closed through a second locking device when the second valve is opened, wherein the first and/or second locking devices can be operated by first and/or second control members.
