Abstract
A stable flow regulator assembly includes a body having an aperture that received a tube. The assembly also includes a worm gear that extends through, and is rotationally movable relative to, the body. A worm wheel is rotationally positioned within the body and is pivotably moved within the body by engagement with the worm gear. The worm wheel also includes a slot, configured to align with the aperture, through which a tube may be extended, and as the worm wheel is moved within the body, the slot and the aperture are moved out of and into alignment to compress and release compression upon the tube.
Claims20
A stable flow regulator comprising:
- a body comprising an entry opening, an exit opening, and an inner surface forming a compression portion;
- a rack linearly movable within the body and comprising teeth;
- and
- a worm gear comprising a gear thread and configured to be rotationally positioned through the body such that the gear thread engage against the teeth of the rack, wherein rotation of the worm gear translates to linear movement of the rack within the body toward the compression portion or away from the compression portion.
A stable flow regulator comprising:
- a body comprising a first side and a second side, where the first side and the second side are configured to be coupled together to form a gear mount, a pressing surface of the body, and any of a rack track or a rack channel;
- a rack positioned between the first side and the second side of the body, the rack comprising the other of the rack track or the rack channel such that the rack is linearly movable, relative to the body;
- and
- a worm gear rotationally positioned in the gear mount and comprising a gear thread, wherein rotation of the worm gear engages the gear teeth against teeth of the rack to move the rack linearly.
A stable flow regulator assembly comprising:
- a stable flow regulator comprising:
- a body comprising an entry opening, an exit opening, and an inner surface forming a compression portion;
- a rack linearly movable within the body and comprising teeth and compression surface;
- and
- a worm gear comprising a gear thread and configured to be rotationally positioned through the body such that the gear thread engage against the teeth of the rack, wherein rotation of the worm gear translates to linear movement of the rack within the body toward the compression portion or away from the compression portion;
- and
- a tube positioned through any of the entry opening and the exit opening, and extending along the compression portion of the body, wherein the tube is between the compression surface of the rack and a complementary compression surface of the body;
- wherein rotation of the worm gear in a first direction causes the rack to move toward from the compression portion such that the tubing is compressed between the compression surface of the rack and a complementary compression surface of the body.
