PROBLEM TO BE SOLVED: To provide a four-way selector valve reducing a pressure loss of a low-pressure refrigerant or the like flowing through a valve body. SOLUTION: The four-way selector valve 1 is equipped with: the valve body 2 having an enclosed space; a first conduit 4 connected to one side of the valve body 2, and communicating with the enclosed space; a second conduit 6 connected to the other side of the valve body 2 and communicating with the enclosed space; a third and fourth conduits 10, 11 arranged adjacently to each other on both sides sandwiching the second conduit 6, communicating with the enclosed space, and having the same inner diameter as that of the second conduit 6; a valve seat 15 having an opening communicating with each of the second to fourth conduits 6, 10, 11 in the valve body 2; and a valve element 14 arranged in the valve seat 15 slidably. The communication status between the first conduit 4 and the third conduit 10, or between the first conduit 4 and the fourth conduit 11 is selectively switched by sliding the valve element 14 in one direction or the other direction. A valve bore diameter of the valve element 14 is set not smaller than the inner diameter of the second conduit to the fourth conduit. COPYRIGHT: (C)2010,JPO&INPIT |
