Latest Patents

One of Kawachi's latest patents is an apparatus for calculating the torque of a variable capacity compressor. This innovative apparatus includes a sensor that detects both internal and external states of an air conditioner. It features an OFF-torque calculator that calculates and stores a steady-state torque just before a clutch is turned off. Additionally, a start torque calculator computes the start torque after the clutch is engaged. The steady-state full-stroke calculator estimates the full-stroke torque based on the compressor's state after the clutch is turned on. Furthermore, a determiner provides the maximum torque value calculated by the other components when the elapsed time after the clutch engagement is less than a predetermined threshold.

Another significant patent involves a compressor design that includes a gas extraction passage within the drive shaft. This design allows for effective gas-liquid separation, ensuring that oil accompanied by blow-by gas is efficiently returned to the crank chamber. This innovative structure minimizes the escape of oil from the suction chamber, enhancing the compressor's overall performance.
