  • ACTUATOR CONTROL DEVICE
    Publication number: 20220271700
    Abstract: An actuator control device supplies electrical power to a plurality of actuators via a plurality of controller units consecutively disposed and connected in one direction. A power supply unit or an input/output and power supply unit is interposed between each arbitrary number of controller units from within the plurality of controller units. In a case that the power supply unit is interposed, the power supply unit supplies electrical power to the block connected on a downstream side in a connecting direction. In a case that the input/output and power supply unit is interposed, the input/output and power supply unit performs input and output of signals to and from an exterior and the block that is connected on the downstream side in the connecting direction, while also supplying electrical power to the block.

  • Gas cylinder
    Patent number: 11421716
    Abstract: A gas cylinder includes supply passages for supplying, to an accommodation chamber, a part of gas supplied to a second port. When the pressure in a first pressure chamber is equal to or lower than a prescribed pressure, a valve element closes a discharge flow passage by the biasing force of a spring member and the pressure in the accommodation chamber. When the pressure in the first pressure chamber exceeds the prescribed pressure, the valve element is moved by the pressure in the first pressure chamber, against the biasing force and the pressure in the accommodation chamber, to thereby open the discharge flow passage.

  • ELECTROMAGNETIC VALVE
    Publication number: 20220260175
    Abstract: An electromagnetic operation part of an electromagnetic valve includes a bobbin, a fixed iron core, a movable iron core, a return spring, a magnetic cover, and a magnetic plate. A coil is would around the bobbin. The fixed iron core and the movable iron core are housed in a bobbin hole extending through the bobbin. The return spring places the movable iron core back into an initial position. The magnetic cover covers the electromagnetic operation part. The magnetic plate provides magnetic coupling between the magnetic cover and the movable iron core. The fixed iron core has a spring housing hole extending within and through the fixed iron core. The return spring is housed in the spring housing hole. A proximal end of the return spring is in contact with the magnetic cover, and a distal end of the return spring is in contact with the movable iron core.

  • Fluid control valve
    Patent number: 11408537
    Abstract: In a fluid control valve, a cylinder chamber includes a first pilot chamber extending from a piston in one of sliding directions. An opening of a first pilot port allowing supply and discharge of fluid is formed in the inner wall of the first pilot chamber. The fluid is accommodated in the first pilot chamber when the piston is in a valve open position, and discharged via the opening when the piston is displaced toward a valve closed position. At least one of the piston and a valve body includes a throttle portion forming, between the piston and the valve body, a throttle path having a cross-sectional area smaller than the area of the opening, after the piston starts being displaced from the valve open position toward the valve closed position.

  • Gate valve
    Patent number: 11402024
    Abstract: A gate valve includes a valve plate and a valve rod that are detachably connected along a rod axis by screwing a connecting screw in a screw hole formed at an end of a valve rod through a screw insertion hole formed in the valve plate. The valve plate includes a contact portion that is in contact with the connecting screw. When the connecting screw is loosened to detach the valve plate from the valve rod, the valve plate is displaced along the rod axis together with the connecting screw via the contact portion to move to a valve-plate detaching position at which the connecting screw comes completely out of the screw hole of the valve rod. Accordingly, the valve plate can be detached from the valve rod easily and reliably even if the valve rod is tightly inserted in the valve plate mounting hole.
