    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 hood for enclosing a radiator and an engine has a hood grille formed in a front surface of the hood. The hood grille includes a front wall, and right and left side walls extending from opposite sides of the front wall. The front wall defines intake openings for drawing in air for the radiator. The right and left side walls include bent portions bent substantially at right angles to the front wall. Opposite end regions thereof are secured to the right and left side walls by fixing devices. Hood grille netting extends over an entire area of the intake openings and covers at least parts of the right and left side walls. The opposite end regions of the hood grille netting are bent to correspond to the bent portions. The hood grille netting is secured to the hood grille by bolts and spacers to define spaces between the hood grille netting and the right and left side walls. These spaces communicate with the intake openings.

    摘要: A four wheel drive vehicle with dirigible front wheels, comprising a main propelling drive transmission, and a front wheel drive transmission connected to the main transmission. The front wheel drive transmission is switchable between a first four wheel drive mode in which the front wheels and the rear wheels are driven at a substantially equal peripheral speed and a second four wheel drive mode in which the front wheels are driven at a higher peripheral speed than the rear wheels. The front wheel drive transmission includes a piston operable by a hydraulic control system including a control valve mechanically interlocked to a steering section of the vehicle for switching the front wheel drive transmission from the first drive mode to the second drive mode. The piston, which normally is biased toward a position for the first drive mode, is movable against the biasing force to a position for the second drive mode when the front wheels are steered to an angle exceeding a predetermined angle.

    摘要: A speed control system for a working vehicle having a stepless transmission with a speed control shaft disposed on one side thereof and shiftable between a driving region and a neutral position. This speed control system includes a shift lever disposed on one side of a driver's section for setting a traveling speed of the tractor, while the speed control shaft of the stepless transmission is disposed on the other side of the driver's section. The shift lever is operatively connected to the speed control shaft through a link mechanism. The link mechanism includes a neutralizing mechanism in an intermediate position thereof adjacent the shift lever for returning the speed control shaft to the neutral position.

    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.
