AI Technical Summary
The return spring in existing braided hoses occupies volume inside the hose, resulting in poor fluid flow. Furthermore, the return spring is prone to friction with the rubber inner tube when bent, which shortens its lifespan.
The system employs a combination structure of a reset tube and a reset spring. The reset tube is sleeved on the outer circumference of the inner rubber tube, and the reset spring is sleeved on the outer circumference of the reset tube. The two parts are connected by threads to avoid direct contact with the inner rubber tube. Combined with the design of the spherical end cap and connecting ring, a stable connection is achieved.
It effectively reduces the bending degree of the braided outer tube, protects the rubber inner tube from friction damage, improves flowability and durability, and facilitates component disassembly and installation.
