<p><P>PROBLEM TO BE SOLVED: To provide a four-circuit protection valve to be used for an air pressure circuit such as a brake system for a vehicle, for producing output pressure with a pressure reducing valve in multiple variation while standardizing a product. <P>SOLUTION: The four-circuit protection valve 100 comprises storage chambers in which a first pressure reducing valve 5A, a second pressure reducing valve 5B and a third pressure reducing valve 5C are built. The first-third pressure reducing valves are each of a piston type. Thus, output pressure from each of output ports 21-24 becomes air pressure, as required, depending on which storage chamber of a valve housing 30 of the valve 100 the pressure reducing valve is assembled in. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
