Latest Patents

Kenjirou Hara holds a patent for a spool valve device, which includes a housing with channels and a spool that moves to change channel connection statuses. The device features an electric actuator that consists of an electric motor and a linear-motion conversion mechanism. The motor rotates an output shaft by torque corresponding to a drive current supplied to it. The mechanism converts the rotational output shaft movement into straight movement, applying thrust to the spool to change its position. Additionally, the device includes a biasing member that applies a force to the spool against the actuator thrust, an angle detector for detecting the motor output shaft's angular position, and a driving portion that controls the motor based on a position command input. An abnormality determining portion calculates the spool position and determines the presence of any operational abnormalities.
