AI Technical Summary
Existing refrigerant circuits in vehicles and heat pumps require numerous actuators, connecting pipes, hoses, and seals, leading to inefficiencies in manufacturing, space utilization, and increased power consumption, with a higher risk of leakage and failure.
A valve block integrating multiple refrigerant valves and a mechanical camshaft for joint control, reducing the need for electromagnets and allowing simultaneous operation of multiple valves, with a modular design that includes a control unit and electric motor for precise angle control of the camshaft.
This design enhances efficiency by reducing manufacturing costs, component count, and power consumption while improving space utilization and reducing leakage risks, particularly in battery electric vehicles.
