    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.
