摘要： A channel-switching valve is provided. The channel-switching valve comprises: a cylindrical valve housing whose one end is closed by a main valve seat; a low pressure outlet and two connecting holes for connecting the inside and the outside of the valve housing; a high pressure inlet for connecting the inside and the outside of the valve housing; and a connecting groove and a guide groove formed on an end surface of a main vale element which is accommodated in the valve housing. When the main valve element is situated in a first rotation position, one of the connecting holes is connected to the low pressure outlet by the connecting groove while the other one of the connecting holes is connected to the high pressure inlet. When the main valve element is situated in a second rotation position, the other one of the connecting holes is connected to the low pressure outlet by the connecting groove while the one of the connecting holes is connected to the high pressure inlet by the guide groove.Both end surfaces of the main valve element are externally connected by an equalizer channel formed inside the valve housing. When the main valve element is rotated between the first rotation position and the second rotation position by a main valve element drive, the lower end surface of the main valve element is separated from the main valve seat by internally connecting both end surfaces by a pilot port which is open as a pilot valve element is moved by a pilot valve element drive.

摘要： In a rotary flow-path exchanging valve, a high pressure side communicating groove 37 is provided to communicate a first exchanging port 23 and a second exchanging port 27 of a valve seat plate 5 with a high pressure side communicating port selectively. A part of a joint pipe 17 to be connected to the high pressure side port 19 is protruded into the high pressure side communicating groove 27. The protruding part constitutes a stopper pipe 20 for limiting the rotatable range of a valve element 1. In installing the stopper pipe 20, it is connected and secured to the high pressure side port 19 of the valve seat plate 5, and thereafter is hardened by plastic deformation processing. Thus, when the stopper pipe is heated by soldering for its securing to the valve seat 5, the necessary strength thereof can be maintained.
