Abstract
A self-sealing hydraulic device has a connecting assembly and a hydraulic assembly. The connecting assembly has an adaptor having a shell, a male fitting, and a barb fitting. The male fitting is mounted in the shell, is axially moveable relative to the shell, and has an axial hole and a radial hole orthogonally communicating with the axial hole. The radial hole is sealed by the shell. The barb fitting is connected to and communicates with both the shell and a hose. The hydraulic assembly is assembleable to the connecting assembly and has a housing, an elastic element, and a valve unit. The housing has a hydraulic chamber and an assembling hole communicating with the hydraulic chamber via a through hole. The elastic element is disposed in the housing. The valve unit is disposed inside the hydraulic chamber and driven by the elastic element to seal the through hole.
