Abstract: A device for providing a signal warning of a clogging of a dust filter. A pair of air flow speed sensors A and B are arranged downstream of two sections of a dust filter 1 arranged in an air duct 1, and the outputs of the sensors A and B are connected to a comparator 6 having an output connected to a warning device 7. An obstacle 3 is arranged upstream or downstream of one section of the filter 1. When the filter is new, the speed of the air flow detected by the sensor B without an obstacle is higher than that detected by the sensor A located downstream of the obstacle, but the speed of clogging at the section without an obstacle is much higher than that at the section located downstream of the obstacle, and thus, after continuous use, the air speed detected by the sensor B becomes equal to that detected by the sensor A. The values of the detected speeds are compared to determine a degree of clogging of the filter, and to issue a warning signal when needed.

Abstract: A drain structure for a fluid filter includes a cap internally forming a drain hole. The cap receives a valve member urged by an urging means in a direction, in which the valve member blocks the drain hole. Normally, the drain hole is blocked with a drain member. When fluid is drained from the drain hole, the drain member is removed from the drain hole, and a drain tool is inserted into the drain hole, so that the drain tool displaces the valve member in a direction, in which the drain hole is unblocked. The drain tool has a hooking portion that can hook to a hooked portion provided to the cap by axially rotating the drain tool inserted into the drain hole of the cap. Thus, the drain tool can be connected with the cap while the hooking portion is supported by the hooked portion.

Abstract: An oil filter has a drain hole, which is internally blocked with a valve member. When oil remaining in the oil filter is drained, a drainpipe is inserted into the drain hole, so that the valve member is displaced and remaining oil is drained from the drain hole. This valve member has an annular recession to steadily support an upper end of the inserted drainpipe. Therefore, gripping force of the drainpipe is enhanced without decreasing draining performance. The drainpipe and the oil filter are connected with each other via a seal member that is provided to the oil filter. The drainpipe 80 has a removing means that holds at least a part of the seal member to pick the seal member off the oil filter, when the inserted drainpipe is detached from the drain hole. Thus, the seal member can be removed simultaneously with the drainpipe from the oil filter.

Abstract translation: 油过滤器具有排水孔，其内部被阀构件封闭。 当油滤清器中残留的油被排出时，将排水管插入到排水孔中，使得阀构件移位，剩余的油从排水孔排出。 该阀构件具有环形凹部以稳定地支撑插入的排水管的上端。 因此，排水管的夹持力增强而不降低排水性能。 排水管和油过滤器通过设置在油过滤器上的密封构件相互连接。 排水管80具有除去装置，当从插入孔分离插入的排水管时，保持至少一部分密封构件以将密封构件从油过滤器上取出。 因此，密封构件可以与排油管同时从油过滤器去除。

Abstract: A slurry of suspended formation fiber and binder fiber is brought to pass through a suction unit to form a molded member. Longitudinally extending channel portions are formed on both inner and outer peripheral surfaces of the molded member, and a wall portion is formed to close one end of the channel portions of the inner peripheral surface. Further, opposite surfaces of the channel portion at the other end of the molded member are closed by pressing from outside and bonded by binder resin which is impregnated into the molded member.

Abstract: A filter element for use in an oil filter is composed of main fibers of at least 5 .mu.m diameter and micro fibers of less than 5 .mu.m diameter. The micro fibers are filled in a density of 0.005 to 0.02 g/cm.sup.3. A slurry including the fibers is drawn into a suction unit through suction openings to form a molded body. The filter element is given a density gradient such that the micro fibers are denser in the inner periphery than in the outer periphery. Following the drawing step, the molded body together with the inner mold is removed for subsequent dehydration and heating. During those processes the inner mold is kept located within the molded body.

Abstract: The invention provides a drain mechanism of a fluid filter in which a heated fluid is not splashed on a worker at a time of discharging the fluid such as a time of exchanging an element, and can inhibit dusts or the like from being mixed from an external portion at a time of normal use. A drain mechanism 7 of the present invention is provided with a cap 3 engaged with a case 2 and having a drain hole 15, a drain member (a drain plug 20) detachably mounted to the cap from an outer side thereof and closing the drain hole, a valve member 25 provided in an inner side of the cap and closing the drain hole, and an elastic means (a spring 11) for energizing the valve member in a direction of closing the drain hole. In a state in which the drain member is detached from the cap, a residual fluid within a housing is discharged by a tubular draining jig 30 inserted to the drain hole.
