<p>PURPOSE: To provide a valve highly pressure-proof and lightweight by providing a spool formed of high-strength carbon fiber reinforced plastic and a case formed of a light metal in the valve with spool urged in the closing direction by a close spring fitted in a case. CONSTITUTION: A spool 1 formed of a high-strength carbon fiber reinforced plastic having a plurality of recesses for distributing a fluid in an intermediate part is fitted in a hollow part 2 of a case 3 formed of a light metal or a light metal alloy movably in the axial direction. A valve seat area 5 is closed by urging the spool 1 to the left by a close spring 7 to stop the flow from a supply passage 4 opened in an intermediate portion of the intermediate part 2 to an adjacent space 15. A manually rotatable cam shaft 12 is provided to operate a valve, the spool 1 is allowed to slide along a cam groove 13 through a spherical body 14 by this rotation, and the valve seat area 5 is opened by the movement to the left to allow the fluid to be distributed.</p> |
