Latest Patents
Kuroshima's latest patents include two groundbreaking designs for scroll compressors. The first patent describes a scroll compressor with valved ports for each compression chamber. This design features two groups of communication ports formed in the end plate of a stationary scroll member. Each group includes multiple communication ports, and a lead valve is associated with each group. This valve operates based on pressure differentials, effectively preventing over-compression in the compression chamber.
The second patent outlines a scroll compressor with closed compression spaces that have valves to reduce loading torque upon starting. This design includes an orbiting scroll and a fixed scroll, each with a spiral wrap. The closed spaces defined by these wraps are moved toward the center of the scrolls, allowing for efficient compression of the fluid. The innovative use of valves facilitates communication between spaces, reducing the loading torque during startup.
