PILOT VALVE SWITCH MECHANISM AND A COMBINED SHOWER APPLIED WITH THE PILOT VALVE SWITCH MECHANISM

摘要

A pilot valve switch mechanism and combined shower applied with the pilot valve switch mechanism includes a fixed portion and a valve spool. The fixed portion includes an inlet waterway, a first outlet waterway, a second outlet waterway and a control hole capable to connect to the outlet waterways. The first outlet waterway has a first outlet. The second outlet waterway has a second outlet. The valve spool is slidably assembled inside the fixed portion along the inlet waterway, with a slim hole connected to the inlet waterway. The valve spool and the fixed portion form a pressure cavity, which is connected to the control hole and the slim hole. The control hole controls the water pressure of the pressure cavity to drive the valve spool to close the first or second outlet, connecting the inlet waterway to the first or second outlet waterway. The control hole switches the waterways.
