  • Publication number: 20210304937
    Abstract: A controller for a linear solenoid valve is configured to: calculate an average value of an exciting current within a period including a natural number multiple of the dither cycle as an average current value; execute a feedback control on a control value of the pulse width modulation signal such that a target value of the exciting current and the average current value match; and calculate a dither correction amount by multiplying a ratio between the control value of the pulse width modulation signal obtained by the feedback control and the average current value by a dither current value that is a current value corresponding to the dither correction amount and calculating the dither correction amount such that an increase in the exciting current due to the dither correction amount is canceled out by a decrease in the exciting current due to the dither correction amount within one dither cycle.

  • Patent number: 6638036
    Abstract: A ventilating device capable of being easily assembled and disassembled, wherein, after setting a blower for exhaust and a blower for air supply on an electric motor (55), the electric motor is installed in an exhaust flow path (122) of a silencer box (100). The inside of the silencer box (100) is divided by partitions into the exhaust flow paths (122, 123) and air supply flow paths (132, 134) and sound absorbing material is installed on the wall surfaces of the air flow paths (122, 123, 132 and 134). Each blower aligns with each of the air flow paths when an air blow device is inserted, and an opening into which the air blow device is inserted is covered by a cover (150). The blowers can be assembled and disassembled from the side and the air blow devices can be inserted from the upper side.
