Multi-stream rotary fluid distribution system

A rotary fluid distribution apparatus comprising:

• a first head having a wall extending around an interior volume thereof, said wall having a first orifice formed through said wall so as to open to said interior volume and a second orifice formed through said wall so as to open to said interior volume, said first head having a first flowpath and a second flowpath communicating with said interior volume thereof;
• a rotor extending through said interior volume;
• a first separation plate positioned within said first head, said first separation plate having an opening formed therethrough, said first separation plate defining a first fluid section and a second fluid section within said head;
• a second separation plate positioned within said first head in spaced relation to said first separation plate, said second separation plate having a first opening and a second opening formed therein;
• a tunneling channel extending across said second fluid section and in communication between said opening of said first separation plate and in communication with said second opening of said second separation plate, said tunneling channel being movable relative to a rotation of said rotor;
• a purge section positioned in said first head and on a side of said second separation plate opposite said first fluid section, said purge section having at least one hole opening on a side thereof opposite said second separation plate.

• a rotor extending through said interior volume;
• a first separation plate positioned within said first head, said first separation plate having an opening formed therethrough, said first separation plate defining a first fluid section and a second fluid section within said head;
• a second separation plate positioned within said first head in spaced relation to said first separation plate, said second separation plate having a first opening and a second opening formed therein;
• a tunneling channel extending across said second fluid section and in communication between said opening of said first separation plate and in communication with said second opening of said second separation plate, said tunneling channel being movable relative to a rotation of said rotor;
• a center body positioned at an end of said first head, said center body communicating with said first flowpath and said second flowpath, said rotor having a portion extending through said center body, said rotor being rotatable independently of said center body.

A rotary fluid distribution apparatus comprising:

• a head having a wall extending around an interior volume thereof, said head having fixed fluid inlets and fixed fluid outlets;
• a rotor extending through said interior volume, said rotor having an end surface adjacent said fixed fluid inlets and said fixed fluid outlets, said rotor comprising:
• a plurality of fluid sections in a stacked configuration, a first fluid section of said plurality of fluid sections formed adjacent said end surface of said rotor, a second fluid section of said plurality of fluid sections formed adjacent said first fluid section opposite said end plate, a third fluid section of said plurality of fluid sections formed adjacent said second fluid section opposite said first fluid section;
• a plurality of tunneling channels formed within said rotor, a first tunneling channel of said plurality of tunneling channels opening at a first end through said end surface to one of said fixed fluid inlets and said fixed fluid outlets and opening at a second end to said first fluid section of said plurality of fluid sections, a second tunneling channel of said plurality of tunneling channels opening at a first end through said end surface to another of said fixed fluid inlets and said fixed fluid outlets and opening at a second end to said second fluid section, a third tunneling channel of said plurality of tunneling channels opening at a first end through said end surface to yet another of said fixed fluid inlets and said fixed fluid outlets and opening at a second end to said third fluid section.
