Embodiment Construction
[0024] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principles of the present invention.
[0025] This embodiment provides a flow compensation device for a multi-stage synchronous telescopic oil cylinder. Two two-position two-way valves in pairs are installed inside the piston, which can move with the piston; the two-position two-way valve is a stroke-triggered Two-position two-way valve, one end of the two-position two-way valve has a stroke trigger switch. When the two-position two-way valve moves to the limit position with the piston, due to the contact between the stroke trigger switch and the external barrier (the end surface of the adjacent cylinder and the corresponding adjacent to the piston end face of the oil cylinder), an external ...
