Abstract
PURPOSE:To move a spool in the axial direction so as to switch the connection of respective ports and adjust the flow rate in turning the spool by forming a rectangular hole in a sleeve while providing an axial groove in the spool. CONSTITUTION:Inside of a sleeve inserted into a body 12, a spool 10 is slided in the axial direction so as to be rotatably inserted. In the sleeve 13, there is formed holes 9 in such a way that the length in half of the whole circumference of the sleeve 13 is divided into four holes. Thus, it is possible to switch the connection relation among ports C1, C2, T and P in moving the spool 10 in the axial direction and freely change the opening area so as to control the flow rate in rotation of the spool 10.
