Rotary valve with interconnecting stator and rotor channels
The patent US12038091B2 describes a rotary valve designed to facilitate fluid communication through a unique configuration of stator and rotor members. The stator member features a planar face with multiple stator channels, while the rotor member, also with a planar face, contains a rotor channel. The rotor is rotatable about a defined axis, allowing the rotor channel to interconnect two stator channels in a conducting position. Notably, at least one stator channel includes a transverse section that opens into the stator face, and the rotor channel is designed to elongate the inner surface of the stator channel when in the conducting position. The rotor channel is characterized as a groove that is fully open towards the rotor face, with its bottom inclined to match the angle of the stator channel, ensuring a seamless fluid flow.
Further claims detail specific configurations of the rotary valve, including the shape of the rotor channel, which may have a U-shaped cross-section, and the orientation of its bottom at various interconnection ends. The design allows for radial or tangential extension of the rotor channel relative to the rotation axis. Additional features include a parallel stator channel that runs alongside the rotation axis, with sections that connect to the rotor channel and a connection port. The patent also describes a circular groove surrounding the stator face, which has an inclined surface that aligns with the transverse channel section. This innovative design aims to enhance the efficiency and functionality of fluid control in various applications.
