Abstract: A linear motor-actuated flow control valve includes: a casing having an inlet port and an outlet port; a moving-coil linear motor disposed within said casing, said linear motor including a hollow, ferromagnetic core which delimits the interior of said casing into valve chambers and which has a valve hole or holes for communicating said inlet and outlet ports with each other, a bobbin slidably disposed on said core for controlling the opening degree of the valve hole(s), an electromagnetic coil wound on said bobbin, a permanent magnet so arranged that the magnetic flux produced thereby extends axially of said electromagnetic coil, and a magnetic body for forming a magnetic circuit, in cooperation with said core, for the flux produced by said permanent magnet; and spring for biasing said bobbin so that said bobbin is retained at a predetermined position by said spring means when said electromagnetic coil is in the de-energized state, whereby said valve hole(s) is/are held open or closed to a predetermined degre

Abstract: A hydraulic fluid reservoir for automobile including a plurality of fluid chambers separated by a partition, the fluid chambers being communicated with hydraulic systems in the automobile respectively, and a baffle plate between the upper end of the partition and an inlet at the upper portion of a reservoir body to define openings of the respective fluid chambers at predetermined ratios which define the flow rates of fluid into respective fluid chambers.

Abstract: A hydraulic fluid reservoir for automobile including a partition wall within a reservoir casing defining a float chamber and extending from the bottom of the reservoir casing, a float which is movable in said float chamber so as to cause a switch to close or open at a predetermined float level, a communication opening communicating the float chamber with the outside chamber of the partition wall at the lower portion thereof and a fluid reflection cover disposed on the float chamber, malfunction of the level detector is avoided.

Abstract: A linear motor-actuated flow control valve includes spring means for biasing a bobbin controlling valve hole opening degree in mutually opposing directions, to hold the bobbin at a middle opened position when an electromagnetic coil wound on the bobbin is deenergized. The bobbin is driven against spring means force in any opposing directions to increase or decrease the opening degree by applying a positive or negative energizing current to the coil.
