  • Patent number: 11028864
    Abstract: A control loop for a double-acting pneumatic actuator is configured to generate two control signals, one for each of the two pneumatic chambers for the purpose of controlling the actuator position in view of operating constraints on the chamber pressures or the stiffness of the actuator. A numerical indicator of the stiffness may be computed in a variety of ways, for example, as the average of the two chamber pressures. In one embodiment a numerical indicator of stiffness is treated as an output of the system along with the position of the actuator. A multi-input multi-output control loop with position and pressure feedback may be used to simultaneously control the position and the stiffness of the actuator.

  • Patent number: 10584803
    Abstract: A solenoid valve includes: a cylindrical spool that has an annular groove in an outer surface and moves along an axial direction under a driving force generated by a current being applied to a solenoid part; a cylindrical sleeve that has a through-hole capable of communicating with the annular groove and houses the spool; and an urging member that urges the spool by an urging force acting in a direction opposite from a direction in which the driving force is generated. When no current is applied to the solenoid part, a part of the through-hole communicates with the annular groove. When a current is applied to the solenoid part, an area of communication between the through-hole and the annular groove increases as the spool moves under the driving force acting against the urging force.

  • Patent number: 10533677
    Abstract: In a linear solenoid valve, a coil wound on a bobbin is disposed radially outside a first core and a second core of that configure a part of a core segment, and a cover portion is formed by filling the outer periphery of the coil with a resin material so that the coil and the core segment are integrally molded together. The first core includes a small diameter portion having an outside diameter r2 smaller than an outside diameter r1 of an outer tubular portion that is part of the second core and that is opposed to the coil, and a large diameter portion that has an outside diameter r3 larger than that of the small diameter portion. A space between the small diameter portion and the bobbin makes it less likely that the first core is pressed radially inward via the bobbin during formation of the cover portion.
