A drive cam is rotated about a camshaft member upon application a drive torque of a drive source to the drive cam. A transmission device converts rotational motion of the drive cam into linear reciprocating motion and transmits the converted linear reciprocating motion to a control shaft member. The control shaft member is connected to a controlled subject and is linearly reciprocated together with the transmission device in an axial direction. A reverse input cutoff clutch transmits the drive torque, which is received from the drive source, to the drive cam. The reverse input cutoff clutch non-rotatably locks an output shaft of the drive source in response to a reverser input torque transmitted from the controlled subject through the drive cam.

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 mechanismof the present invention is provided with a capengaged with a caseand having a drain hole, a drain member (a drain plug) detachably mounted to the cap from an outer side thereof and closing the drain hole, a valve memberprovided in an inner side of the cap and closing the drain hole, and an elastic means (a spring) 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 jiginserted to the drain hole.

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.

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 drainpipehas 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.

An oil pump for an internal combustion engine is provided with an intake port and a discharge port, each formed in a pump housing. The oil pump has a power pump serving as a first main pump and an electric pump serving as a second auxiliary pump, both of which may be contained in a same pump housing. The power pump is rotated by a driving force of a crankshaft, and the electric pump is rotated by the driving force of an electric motor. This makes it possible to reduce the maximum capacity of the power pump serving as the main pump. In a vehicle operating range where the oil discharging pressure generated by the power pump becomes insufficient, the electric pump serving as the auxiliary pump is operated together with the power pump such that appropriate oil discharging pressure or appropriate oil discharging quantity can be achieved. The electric pump may also be allowed to operate for a period of time after shutting off of the engine.

A protector for holding a filter medium thereon is made of resin and composed of a plurality of pillar members. The pillar members are disposed in parallel with each other in a longitudinal direction thereof and forming a circular shape with intervals respectively between adjacent two pillar members. Accordingly, the protector can be easily manufactured by molding and can be easily scrapped after its use. The protector further has a positioning member for positioning the protector in a case. Accordingly, a number of parts in a filter device can be reduced, resulting in a decrease in man-hours for assembling the parts.

Protector for holding filter medium

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.

Method of manufacturing a filter having longitudinal channels by molding

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.

An air purifier has discharge electrodes which generate a corona emission. These discharge electrodes are disposed within a flow passage provided in the air purifier along with a blower. Also included in the air purifier is a filter which scavenges contaminant particles in the air charged by the discharge electrodes. A control unit detects a discharge current of the discharge electrodes to control a rotational speed of the blower in accordance with the detected emission current.

Air purifier

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.
