摘要： In a rotary flow-path exchanging valve, the magnetic force generated in a pair of main magnetic pole pieces (66) by energization of an electromagnetic solenoid is acted on a multi-pole magnet (71) of a main valve element accommodated within a valve housing (1) so that the main valve element (3) is rotated to exchange a flow-path. The multi-pole magnet (71) is made of a plastic magnet of plastic material mixed with magnetic powder. The main valve element (3) and multi-pole magnet (71) are integrally formed by multiple molding. A pair of main magnetic pole pieces (66) magnetically connected to one polarity of the electromagnetic solenoid (11) are arranged. A pair of auxiliary magnetic pole pieces (70) connected to the other polarity of the electromagnetic solenoid (11) are arranged at positions out of phase from the magnetic pole pieces by 90.degree.. The pair of auxiliary magnetic poles (70) are opposed to portions of the multi-pole magnet (71) having a reverse polarity to that of portions of the multi-pole magnet (71) opposite to the main magnetic poles (66).

摘要： A rotary channel-selector valve is provided, which includes: a valve-seat plate covering one end of a cylindrical valve housing and provided with low and high pressure ports and two switching ports all connecting the inside and the outside of the valve; and a main valve element accommodated in the valve housing and provided with low and high pressure connecting grooves on one end surface thereof, wherein one (or the other) of the switching ports communicates with the low pressure port through the low pressure connecting groove and simultaneously the other (or one) thereof communicates with the high pressure port through the high pressure connecting groove at a first (or second) channel-switching position of the main valve element. A bulkhead is provided on a bottom surface of the high pressure connecting groove and both end portions of the high pressure connecting groove open to an inner surface of the valve housing through respective high pressure fluid jetting grooves so as to hold stable the main valve element at the first or second channel-switching position. Flow of high pressure fluid jetting to the high pressure connecting groove is then disturbed by the bulkhead, difference in power between flow of the high pressure fluid jetting from the both end portions of the high pressure connecting groove to the periphery of the main valve element through the respective high pressure fluid jetting grooves arises and brings about rotating force to the main valve element, and thus the main valve element being in rotation can surely get to a due channel-switching position.

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.
