Title: Tsutomu Matsuo: Innovator in Hydraulic Drive Technology
Introduction
Tsutomu Matsuo is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of hydraulic drive technology, holding a total of 11 patents. His innovative designs have advanced the functionality and efficiency of industrial vehicles.
Latest Patents
One of Matsuo's latest patents is a hydraulic drive device for industrial vehicles. This device includes a variable displacement pump, a displacement control valve, a power steering cylinder, a power steering valve, a loading cylinder, a loading valve, a hydraulic oil passage, and a pilot line. The displacement control valve is designed to control the variable displacement pump, increasing its displacement when the differential pressure between the discharge pressure of hydraulic oil and the pilot pressure is below a predetermined set pressure. Additionally, the spool of the loading valve features a groove that creates a communication passage between the hydraulic oil passage and the pilot line when the loading valve is in a neutral position.
Another notable invention is a variable displacement pump that operates by moving a piston in response to the inclination angle of a swash plate. This pump includes a control piston that adjusts the inclination angle between a maximal and minimal discharge capacity. The design ensures that when the inclination angle is intermediate, the contact point between the piston and the pressed portion is strategically located to optimize performance.
