Title: Masashi Yanagawa: Innovator in Fluid Dynamics and Vehicle Technology
Introduction
Masashi Yanagawa is a notable inventor based in Kasugai, Japan. He has made significant contributions to the fields of fluid dynamics and vehicle technology, holding a total of 5 patents. His innovative designs have the potential to enhance various applications in these industries.
Latest Patents
One of Yanagawa's latest patents is an electric pump. This electric pump features a transmission unit that transmits the rotational drive of a motor unit, a pump unit, and a rotary valve unit. The pump unit is designed to expand and contract a pump chamber, allowing it to draw in fluid from an inlet and discharge it from an outlet. The rotary valve unit includes a valve body that is rotated by the drive force from the transmission unit. It also has a valve cover with a valve-side inlet for drawing in fluid and multiple fluid outlets for discharging the fluid externally. The rotary valve unit is capable of switching the fluid outlets in accordance with the rotational drive of the valve body, which is intermittently driven by a mechanism that converts continuous drive into intermittent drive.
Another significant invention by Yanagawa is a vehicle seat that incorporates a bladder as an actuator. This vehicle seat includes a pump that supplies air to the bladder, a switch to operate the pump, and a switching valve in the air supply/discharge passage. The switching valve connects the air supply/discharge passage to the pump's discharge port when air is supplied to the bladder and to the exhaust port when air is discharged. The switching valve is integrated into the switch, allowing it to supply and discharge air to and from the bladder based on the switch's operation.
