切換弁。 a main valve block having two cylinder bores in which two opposing valve elements are slidably disposed and whose inner inner surfaces serve as valve seats; A subbore that communicates with two working chambers defined by the outer ends of the cylinder bore and whose inner surfaces at both ends serve as valve seats, and a fluid chamber that communicates with the subbore and is defined between the inner ends of the cinder bore. A sub-valve block having a pilot port whose upper outer surface serves as a valve seat, a ball valve element slidably disposed in the sub-bore, and a pilot valve element seated on the valve seat of the pilot port. 1. A reversible switching valve for an air conditioner, wherein both of the working chambers and the subbore are communicated with each other by a capillary reach tube.
