Title: Toshiaki Otani: Innovator in Hydraulic Systems
Introduction
Toshiaki Otani is a notable inventor based in Sakai, Japan. He has made significant contributions to the field of hydraulic systems, holding a total of 3 patents. His work focuses on improving the efficiency and functionality of hydraulic systems in work machines.
Latest Patents
One of his latest patents is a hydraulic system for work machines. This system includes a first switch valve and a first return circuit. The first switch valve can be switched between a confluent position and an isolation position. In the confluent position, the first operation fluid tube connects to a second operation fluid tube, while the first transmission fluid tube connects to a second transmission fluid tube. Conversely, in the isolation position, the first operation fluid tube is disconnected from the second operation fluid tube.
Another significant patent is for a working machine equipped with a variable displacement hydraulic pump. This innovation allows the working machine to change the maximum value of the absorption torque of the hydraulic pump to a higher value when in a specified state. This addresses issues that arise when the operation lever is used in an intermediate position, which can cause the machine body to swing and affect operability. The system automatically switches to a higher maximum absorption torque setting when full operation is detected.
