Latest Patents

One of Sugizono's notable inventions is a **Variable Delivery Compressor**. This advanced device features multiple compression chambers and reciprocatory compression pistons, designed specifically for air-conditioning circuits in vehicles. The compressor includes a suction chamber that communicates with the compression chambers via suction valves, some of which can be deformed by a valve pressing mechanism, enabling the refrigerant's compression to be adapted according to demand. This mechanism involves an axially movable spool that is actuated by a control unit responsive to cooling load variations.

Another innovative design by Sugizono is the **Variable Delivery Refrigerant Compressor of Double-Acting Swash Plate**. This invention incorporates a delivery control valve arrangement that allows for automatic variation in the compressor's delivery capacity. It achieves this by alternately placing the compressor's compression chambers under 'loaded' and 'unloaded' conditions, based on real-time cooling load requirements. The system utilizes valve means to establish fluid communication passages, enabling selective application of pressure and efficient actuation based on pressure differentials.

Career Highlights

Sugizono's career has been closely linked with **Kabushiki Kaisha Toyoda Jidoshokki Seisakusho**, a leading company in the field of automotive components.
